Alpine Tips
Load transfer: The stirrup hoist
Do you have a big load that you need to move a short distance? Here's one crafty way to do it: the stirrup hoist. This may not be the most efficient method, but it's quick and simple.
Premium Members can read the entire article here:
This is part of a series of articles that cover methods to move a large load a short distance, typically to unweight an anchor. Here are two other related posts.
Load transfer: the 2:1 redirected haul
Load transfer: the alpine block and tackle
In some unusual climbing situations, you may need to lift a very large load a very small distance.
Maybe on a big wall, where you rigged your bags old school style (sheesh, use a docking cord, will ya!?) and you need to lift them a tiny bit to unclip the carabiner.
Maybe in a rescue scenario, when you have an unconscious person hanging off of a loaded anchor, and you need to lift them just enough to unclip them.
In either case, it's often better to use your bodyweight to try to do the lifting rather than your muscles. Work smart, not hard!
Don't make a habit out of this. It's almost always better to use some sort of releasable knot or hitch to anchor your load when you can. But for those cases when you didn't do that for some reason, the stirrup hoist might come in handy!
Here's a way to set that up, called the stirrup hoist.
This is not the most efficient method, but it's pretty fast and uses minimal gear, so it's a good one to have in the toolbox.
You might want to try this first and see if it solves your problem, before you try more elaborate systems, such as the alpine block and tackle, or the 2:1 redirected haul.
Clip a long sling onto the load. Slippery Dyneema would be a good choice, to minimize friction.
Pass the sling through a carabiner on the anchor, and let the sling hang down below the anchor. If you happen to have a pulley, run the sling through that to minimize friction. (In the photo below, I’m not using a pulley.)
Step into this “stirrup”. Your body weight, along with lifting the load with your arms, should hopefully be enough to move it up a bit to solve your problem.
To give a little extra boost, you might try bouncing on the sling ,which will apply more force to the load than your static body weight.

The "Swiss cheese" model of risk mitigation
The “Swiss cheese” model is a metaphor for how risk can be reduced through overlapping and redundant safety systems.
Premium Members can read the entire article here:
The Swiss Cheese model is a metaphor used in safety science. It illustrates how accidents typically occur due to multiple, overlapping failures rather than a single cause.
Each "slice" of cheese represents a layer of defense (such as safety measures or procedures) within a system.
Each “hole” in the cheese symbolizes a potential weakness or failure.
If a hole in one slice of cheese is covered by a solid part of the next slice, you have a partial problem but is not (yet) a catastrophe.
Even if a slice of cheese is only 5% holes, there’s still a small chance that two holes could align, and that's when you could have a serious problem.
How does the Swiss Cheese model apply to climbing?

Keep it quiet for the tie in knot
Whatever conversation you're having, take a break when you or anyone else is tying into the rope.
This is a simple suggestion, but potentially a very important one: Avoid talking to someone when you, or they, are tying into the rope.
When anyone is tying what is potentially the most important knot of your/their life, it's best to give it your undivided attention.
Think of it as the equivalent of packing a parachute. If your friend was packing a parachute, you would hopefully not be distracting them with any sort of chatter, and hopefully they would do the same for you.
What's in my pack: big wall gear by Brent Barghahn
Pro climber Brent Barghahn has some impressive free climbing ascents of El Capitan, and definitely knows a thing or two about what to bring on a big wall. Here's a link to his checklist from a helpful blog article he wrote.

Brent Barghahn, professional climber and humble bad-ass, knows a thing or two about big walls. He has some very impressive free ascents on El Capitan, such as El Corazon, El Nino, and Golden Gate.
He’s also an innovator of climbing gear, much of it for lead rope solo and top rope solo. Check out his company, Avant Climbing.
You can read some detailed stories of his climbing adventures on his blog.
One of his blog posts is a collection of general big wall tips.
The big wall tips are excellent. Many of them you'll find on the Alpinsavvy big wall section, such as:
using a tagline, among others.
In addition to the expert tips is Brent’s schweeeeet gear checklist. Attention to detail is crucial on a big wall, and a solid checklist like this will help you bring most everything you need.
(Yes, it's mostly focused on free climbing, which is beyond the skill level for most of us plodders, but it's still very useful for aid climbing.)
Alpinesavvy Premium Members get a direct link to the gear checklist. If you're not a Premium Member, you'll have to go to Brent’s blog at the link above and click through and find it yourself. My Premium Member article also has a link to a longform video with an interview with Brent and discussion of top rope solo and lead rope solo techniques.
Head scratcher: can you solve this rappel problem?
Think you're good at solving climbing problems on the fly? See if you can figure out this one!
Premium Members can read the entire article here:
This noggin-scratcher was solved in real life by Albin Thunander. Albin is a Swedish IFMGA Guide Candidate, and he shared with me the details of how he dealt with this. You can usually find him in the mountains around Chamonix. Connect with Albin on Instagram: @albinthunander.
I first heard of this trick from @tiffany_hensley, thanks Tiffany!
Think you're good at solving climbing problems on the fly? See if you can figure out this one!
Here's the scenario:
You're at the top of a 100 meter cliff.
There are only two anchors: one at the top and one at 50 meters.
You have one 80 meter rope.
There's no way of making other anchors and you can't walk down.
All you have is basic gear, like a harness, belay device, prusik cord and a couple of slings and carabiners. You don't have a Beal escaper, a tagline, or 25 meters of shoelaces or any other fancy gear.
How do you get safely to the ground?
There's no trick answer; no parachute, bouncing, rope stretching etc. It's actually doable and relatively low-risk, without any death techniques using self-releasing knots or taped-open-carabiner-fifi-hook Ninja trickery.
Treat this as more of a math problem, and not a climbing skills problem.

Answer:
Measure 25 meters of rope. Cut it. (If you don't have a knife, you can cut it on a sharp rock, or run a sling back-and-forth through the rope for a few seconds.)
Tie a bight knot at both ends. Clip one end of the 25 meter rope to the top anchor.
Toss the other end of the 25 meter section of rope. (This effectively makes a new “anchor” 25 meters below the top.)
Rap down this 25 meter single strand with the rest of the rope.

How to safely shorten your tether
Need to shorten your connection to the anchor when using a tether? It's common to unclip and reclip your locking carabiner, but this can increase the chances of clipping it incorrectly. Here's a simple and more secure method.
Premium Members can read the entire article here:
At a busy anchor, especially when you have some distractions, it's quite easy to clip your rappel tether / PAS incorrectly.
I’ve done this myself, and fortunately realized my mistake very soon after, yikes!
The main cause of this problem is often when changing the length of your tether.
A common way to do this is to completely unclip the carabiner from one loop, and then clip it into another.
When you do this, you introduce the chance of clipping it wrong.
Here are two recent accidents where this seemed to be a direct cause. (Both of these reports are from the American Alpine Club’s website called The Prescription, which offers a monthly blog and archive of North American climbing accidents.)
Here's the analysis of one accident from the American Alpine Club:
Laycock’s accident was eerily similar to another recent incident, suffered by a climber in Arizona. Both fallen climbers had tied overhand knots in a 120cm length loop of 20mm sewn webbing to create adjustment pockets for a home-made PAS. This is a common practice. In both cases, it appears that the tether was not clipped correctly with the carabiner, but instead the knot caught in the bottom, non-gated end of the tether carabiner.
Wow, that photo is scary! You can see that clipped like this the knot MAY jam into the carabiner temporarily, even under light bodyweight. This could easily fool you that you are properly connected, when in fact you're absolutely not!
Here's a simple way to pretty much eliminate this problem: keep a locking carabiner as your primary connection to the anchor, always on the end of your tether. To shorten your tether, don't move that carabiner at all. Instead add a second one and use that to adjust the length of your connection.

Accidents in North American Climbing 2023, from the American Alpine Club
Reading about climbing accidents is NOT fun. However, it’s an important way to learn, and hopefully reduce risk and avoid future accidents.
Starting in 1948, the American Alpine Club (AAC) has published an annual summary of reported climbing related accidents in the US and Canada, titled “Accidents in North American Climbing” AAC members get this for free.
(The AAC also publish a monthly accident report “sampler” on their website, called “The Prescription”. This is free, offers an archive of recent accident reports, and is a good representation of what you’ll find in the complete publication.)
I was curious: what other countries publish a similar report?
I made a post asking about this on my Instagram. Many helpful people offered info and links about accident reports from different countries.

How to rappel on marginal anchors
Someday, you'll find yourself at a rappel anchor that is Less Than Ideal. Here are some tips to hopefully get you and your partner down in one piece.
Premium Members can read the entire article here:
image credit: Silas Rossi, @silasrossi
At some point in your alpine climbing, you’ll be forced to use a rappel anchor that’s as sketchy as Donald Trump’s tax returns. Here are some ways to hopefully get you and your partner down in one piece.
Improve the anchor. Is it a strand or two of sun crusted, rock rodent chewed ancient webbing? Get out your cordelette or a sling(s) and leave those behind. Old, weathered webbing can be as weak as 3-ish kN! (See some test results below.) Yes, people have died from this type of anchor failure, don't be the next one. You do have a knife, right?
Remove the garbage. If the anchor looks like the rat’s nest in the above photo, do everybody a favor: cut away the worst parts and leave only the best two or three bits of cord.
Are you arriving at a dodgy anchor from a rappel? Stay on rappel and bounce test the anchor. While secure on the rappel ropes, clip your tether into the masterpoint, and give it a few good bounces. A good bounce on a static tether puts about 3x your body weight onto the anchor. If it holds, good. If it doesn't, you're still backed up on your rappel rope.
Backup the anchor if it all possible with other gear. Send the first and heaviest person down first so the backup can do its job if the primary anchor fails. (Obviously this rule was made by heavy people.) If the anchor holds for the big person, it's likely gonna hold for everybody else, and the last person can remove the backup. If the last person is still sketched, they have the right to leave behind ANY gear they want as a backup. Yep, including that $90 cam, your life is worth it. See video at bottom of page for an example.
Bounce test. Ideally, when you’re backed up to something solid, load the rope and give it a solid bounce. Be sure that the backup is unweighted and doesn’t take any load during this test. As mentioned above, a decent bounce is about 3x your bodyweight, way more force than actually rappelling.
Rappel slowly and smoothly, not like some Special Forces cowboy. Try to keep as much weight on your feet as you can.
If the anchor is truly marginal, the first person down can place gear and clip one strand of the rope to it. If the top anchor fails, this might save the day.

Snow anchors with Black Diamond and Mark Smiley
Black Diamond recently collaborated with IFMGA Guide Mark Smiley to test the strength of different snow anchor configurations. Some of the results were pretty surprising!
This is a great article on the Black Diamond website about recent snow anchor testing by IFMGA Guide Mark Smiley and the Black Diamond team.
They did a superb job on it, so I'm gonna send you to the link and have you read it there.
The focus is on rappel anchors, but the results are applicable to crevasse rescue anchors as well.
Even better, Mark gives access to a free sample lesson on T slot / deadman anchors from his online class, The Ultimate Guide To Modern Alpinism, as a link from the BD article, so check it out.
Here’s a table summarizing some of the results.
Takeaways:
Bounce test your anchor before using. If you give it a really good jump, you should test the anchor with about three times your body weight.
Rappel as smoothly as possible.
Buried Snickers bar, not so good. Buried Tyvek envelope, #ProbablySuperGoodEnough.
And a buried 2x4? Stronger then you think! Next time you need an snow anchor, might want to look around for a tree branch.

The frugal climber’s stick clip
Do you enjoy ankle breaking ground fall potential with the crux just before the first bolt? (Smith Rock Oregon, I'm looking at you!) Cool, neither do I. Enter the frugal climber’s stick clip. All you need is a stick, some tape, and a rock.
Premium Members can read the entire article here:
If your personal ethics allow it (and mine definitely do), stick clips are great.
Sure, those super long extendable fiberglass poles with some fancy carabiner-grabber-thingie on the end work sweeeet, especially for really high bolts.
However, for the frugal climber, there's the time-honored dirtbag method.
All you need is some a small rock and a stick. Tape or a rubber band are nice, but optional.
Left photo: tape method. This is my preference, it's a bit more reliable. Tip, tape the middle part of the carabiner as shown here, keeps it more stable. A sturdy rubber band or two works pretty much the same way. (Note that depending on the quality of your tape, this might leave some sticky stuff on your carabiner, which is not so great.)
Right photo: forked stick method. This is a bit more finicky, and you usually have to pull some downward tension on the rope to keep the top carabiner from flopping around. (Yes, in the photo it’s hard to see a stick there, but trust me, there is. =^)

Can (or should) you resling cams yourself?
The webbing on your cam slings has a lifespan of about 10 years. What do you do then? Ideally, send it to the manufacturer for replacement, but that's not always possible. Here are some DIY options, and a list of all known places you can get replacement cam slings.
Premium Members can read the entire article here:
image: HowNOT2, https://www.youtube.com/watch?v=M19taMAZHp4
The generally accepted maximum lifespan of soft goods like nylon, Dyneema, and yes, slings on your cams, is around 10 years. If you use them heavily, it could be a lot less than that.
Reslinging a cam is not a money-making venture by the manufacturer or pretty much anybody else. Also, a manufacturer will almost always only resling their own cams.
If you live in the US, and a few places in Europe, getting this done by the factory is a possibility. But, if you’re outside this area (or if you live in Europe, and have cams made by Black Diamond) sending them directly to the manufacturer for sling replacement is probably not be cost effective.
So, what about replacing those cam slings yourself?
Here are some break test results of various DIY cam sling replacement options tested my friend Ryan Jenks, the mad scientist gear-breaking founder of HowNOT2.
(Disclaimer, these were tested on a limited number, your mileage may vary, if you want to be certain it's done right, then send ‘em back to the factory.)
Summary:
A 30 cm Dyneema sling doubled with a basket hitch is probably going to be your best bet. Be sure and clip both strands! Broke at 17.2 kN.
A 30 cm Dyneema sling tied in a double bowline on a bight also works. Broke between 10 and 13 kN, based on sling width. (Interestingly, the 8 mm sling tested stronger than the 11 mm sling.)
Avoid a girth hitch! Broke at 9 kN, and will probably mess up your cam. (Interestingly, it broke at 9-ish kN both on the slow pull and in the drop tower.)
Or, if you want to skip it entirely, cut off the sling and clip a short quick draw to it, good to go.
Cam reslinging companies
This information is current as of 2024. Of course, policies can change, so check before you mail anything.
If you know anyone who reslings cams who is not on this list, please email me so I can add them, thanks!

De-cluster your anchor with the ”revolving door”
Sometimes at a busy anchor, you may have a rope on top of another one, and those two ropes need to trade places. Here's an elegant way to do this: the "revolving door" technique.
Premium members can read the complete article here:
At a busy anchor (maybe with several people, or a big wall) it's very common to have one rope/cord/sling under another one.
For whatever reason, sometimes those ropes need to “trade places”, as in, the top rope needs to be on the bottom, or vice versa. How can you (easily) do this?
You might be tempted to try the “anchor limbo” by physically shimmying underneath the rope, or maybe even untying completely to move the rope above or below the other one. I’ve done both, and they both suck.
But there’s a much simpler (and elegant) method: the “revolving door”.
It's deceptively simple, and to my eye, looked like a bit of a magic trick the first few times I did it. Once you learn it, you might laugh at how easy it is!
To do this, you need two things: 1) the rope that you need to move above or below needs to be clipped to a carabiner, and 2) the rope needs to NOT have a giant load on it.
Brief description: say you have a rope on the top, and it needs to be on the bottom/under of what we’ll call the “fixed” rope.
Go to the carabiner that's clipped to the fixed rope. The gate on this carabiner needs to be facing up.
Open the carabiner.
Clip the “top” rope into the carabiner.
Here's the key move: Spin (aka “revolve”) the carabiner 180°.
Now, the gate on the carabiner should be facing down. Open the carabiner, and unclip the bottom rope.
Schweeeet! The “top” rope is now UNDER the fixed rope! Give yourself a high five for being so clever. =^)
You probably will want to revolve the carabiner back again to its original position, with the gate up. If it was a locker, relock it.
Like I said, kind of magical! Definitely a #CraftyRopeTrick!

Load transfer - The 2:1 redirected haul
Do you have a big load that you need to move a short distance? Here's one crafty way to do it: the big waller's trick of the "far end haul". aka 2:1 redirected haul. (I learned this from big wall expert Mark Hudon, thanks Mark!)
Premium Members can read the entire article here:
This is part of a series of articles that cover methods to move a large load a short distance, typically to unweight an anchor. Here are two other related posts.
Load transfer: the stirrup hoist
Load transfer: the alpine block and tackle
I learned this trick from big wall expert Mark Hudon, thanks Mark!
You may find yourself in a climbing situation where you need to transfer a BIG load from one anchor point to another.
Beginner big wall climbers, you know what I'm talking about; you clipped the haul bag in the wrong spot and it needs to get moved, whoops! (I’m an expert on this particular mistake; I probably did it five times on my first wall . . .)
Maybe a rescue situation (which you’re hopefully never in) where you need to lift the weight of your uncooperative partner off of the anchor to continue rappelling.
How can you do this the SMART way?
Brute force powerlifting is probably not going to cut it. It's much smarter to use a little mechanical advantage to make this happen. Work smart, not hard!
Here's one method: a redirected 2:1 haul with a progress capture pulley. In the big wall world this is known as the “far end haul”; here's an article on that.
The steps here might appear complicated when you see them the first time, but as soon as you give it a try you'll learn how easy it is.
Look through the step-by-step photos below and then watch a how-to video at the bottom.
You have a big load on the right anchor, and you need to move it to the left anchor. How do you do this the smart way?
Here’s a step-by-step sequence, with a tutorial video at the bottom.
Clip some cord or rope to the anchor.
Clip your progress capture pulley such as a Petzl Traxion, onto the rope is shown. (Remember to clip it “teeth to tail”, so the “teeth” on the device point to the “tail” side that you’re going to pull.)
Clip the Traxion onto the load.
Add a redirect to the anchor. A pulley is good here if you have it. In this example, I’m using the excellent Petzl Rollclip.
(In this example I clipped the redirect on to the anchor on the right. It also works fine if you clip it to the anchor on the left.)
Now you're ready to pull.
Put the rope or cord through a Grigri or a Munter hitch on your harness.
Pull DOWN with your body weight.
As you do this, you’re raising the load with a 2:1 mechanical advantage, and the Traxion pulley captures your progress. Nice!
With the high-efficiency Traxion on the load and the Rollclip/pulley on the redirect, your loss of pulling force due to friction is minimized.

Rope anchors: the Alex Honnold anchor
Here's a fast and simple method to build an anchor using the rope, typically on two good bolts. (Alex says it's his favorite, so that's what I'm calling it. =^)
Premium members can read the complete article here:
Did you realize halfway up the pitch that you left your long anchor sling with your partner down below? Whoops! Better have a Plan B.
Here’s one of several options: use the rope.
Did Alex invent this anchor style? No, climbers have been using this for decades. But, Alex said in an interview that this is his favorite style of anchor for roped multipitch climbing, so that's what I'm calling it. =^)
(Note: one of Alex's regular partners told me that Alex typically belays with a Grigri and not a plaquette style device like shown in the photo, but the basic anchor set up is still the same.)
This anchor is a fine choice when you have a pair of decent bolts.
Note that the belayer is not on the equalized portion of the anchor. They’re clipped directly to one bolt, and indirectly attached to both. The belayer has redundancy, but not equalization.
With properly placed bolts that can each hold well over 20 kN, this shouldn’t be a problem.
This is one of LOTS of ways to make an anchor with the rope. Here are a few more.
Benefits of building an anchor with the rope:
Typically uses the minimal amount of gear. No need for extra slings, cords, or untying slings with knots when you’re done.
Uses the strong and stretchy rope, which you always have. Strong and stretchy are good things to have in an anchor! (Even if you prefer making anchors with a sling or cord, you might not always have those, and it's good to have some alternatives.)
Downsides to building an anchor with the rope:
It works best if you’re swinging leads on a multipitch climb. If one person is doing all the leading (aka block leading), or if this is the last anchor at the top of a climb and you’re transitioning to rappel, it may be better to craft an anchor from a sling or cordelette so you have both ends of the rope to work with. (Even if you plan on swinging leads, your partner might decide they don't want to take their turn and you might have to go again, so keep that in mind.)
Rope anchors can make many self-rescue techniques more challenging, because the end of the rope is a component of the anchor. Yes the belayer can can simply untie and they're out of the system, but then they may have a harder time using the rope for anything useful.
If the next (or previous) pitch is a real rope stretcher and you might need every bit of it, this may not be the best choice. (Rare, but it can happen.)
When the leader pulls up the rope on the second, the rope pull comes tight first onto the anchor and not directly onto the second climber. This can create a few meters of potentially unwanted slack when the second breaks down the anchor. The second can clip to one bolt or piece of solid gear with a tether before they remove the anchor, as a possible solution.

How strong is a “stabbed” rope?
Plodding along on a glacier climb, you get a little careless and CHUNK, your crampon spike goes straight through the middle of the rope in front of you. Does this dangerously compromise the strength of your rope? I tested it with HowNOT2, here are the results.
Premium members can read the complete article here:
Scenarios for a “stabbed” rope . . .
Top rope ice, climbing, you carelessly swing your tool, and CHUNK, you drive your pick straight into the rope. Whoops!
Walking in a rope team on a glacier. A careless step and you stab the rope with your crampon. Whoops!
If you do either of these, does it completely compromise the strength of your rope?
I've always wondered about this, so I tested it on my latest visit to the gear-breaking mad scientist genius Ryan Jenks from HowNOT2.com.
The rope we tested was a Beal Opera 8.5 mm, common for glacier travel.
Disclaimer, yes, results will probably be different depending on rope diameter, size of the spike, type of sheath used in the rope, etc. We had a small sample size. This is what we got, don't take it as gospel.
Test 1: Crampon stab through the rope?!
Broke at 11.9 kN. It broke in the knot, and NOT in the “stabbed” part of the rope.
That's close to full strength of the rope.

Can you girth hitch a Dyneema sling to a picket?
Can you tie a sling directly to a picket hole? Is it going to be strong enough to catch a fall or use as a anchor in crevasse rescue? I did the testing, and have a broken picket to prove it.
Premium members can read the complete article here:
If you’re trying to shave weight on an alpine climb, you might wonder: is it okay to girth hitch a sling directly to a picket?
(Yeah I know, cool Euro climbers don't use pickets and make an anchor out of a buried pack of Gitanes, but that's a different topic.)
Does this dangerously weaken the sling?
Is the sling gonna get cut on the sharper bend radius of the picket hole?
Should I use the sling full strength (about 22 kN) and clip it with a carabiner like normal?
All good questions! I was curious about them as well. So I took a visit to the gear breaking lab of mad scientist Ryan Jenks, aka Mr. HowNOT2, to find out.
We used older Dyneema slings hitched through the middle hole on an older style MSR Coyote picket.
The girth hitch tested at a bit over 10 kN.
(Yes, with a limited sample size of 1.) For me, that's acceptable for a crevasse rescue anchor, because your picket is going to pull out of the snow before you approach that much force.
Not that you should ever be generating a load like that in a standard crevasse rescue to begin with . . .
But hey, if you want to use the sling full strength at 22+ kN, then clip it to the picket with a carabiner, your choice!
Next we tried a basket hitch. As expected, that was a bit stronger, around 16 kN.
After that, just for fun, we doubled the sling through the hole; a double basket hitch. (Yes, we kept using the same picket for every test, so it might've been weakened after the first two .)
Here's what happened. The sling it was fine. The picket broke 18.4 kN!

The challenge you have in both cases is the gear you're trying to clean is being tensioned by the rope under your bodyweight, and that's usually a pretty big problem.
Here’s a simple way to solve it: an adjustable tether plus an aid climbing fifi hook.
I‘ve used this on the infamously traversing bolt ladder on Monkey Face at Smith Rock Oregon, and it works perfecto.
Be sure your fifi has a “release cord” loop tied into the top hole as we see here. This is key to be able to release this under load.
They usually don't come this way from the store, you have to add it yourself. I'm simply using parachute cord.
Notes . . .
It’s pretty much the same procedure for cleaning quickdraws from a steep sport climbing route, but that's a bit easier than this.
Yes, there are several methods you can use to accomplish this, but after you try this you may not wanna do the others. Give different techniques a try and see which works best for you.
What's sweet about this for aid climbing is that it uses gear that you already have on your harness. Typically you would only use a fifi when leading, but in this case, you remove it from your harness and put it on your tether when needed for cleaning.

Klemheist ver 2.0: stitching IN the knot
A Klemheist is a useful friction hitch / rope grabber, but DANG, have you ever tried to use it to actually go up to fixed rope? Tied in the normal way, that sucker bites down hard and is really difficult to slide! Here’s a clever variation that gives adequate grab on the rope, and is much easier to slide when you need to move up.

Left photo, normal way to tie a Klemheist. Right photo, the modified method which is much easier to slide.
The Klemheist is one of three friction hitches every climber ought to know. (The other two are the prusik and the autoblock, aka French prusik, or Machard.)
Friction hitches are used typically used as a rope grab in a mechanical advantage haul system, and as a tool for emergency rope ascending.
The Klemheist is handy because you can tie it with either cord or a sewn sling, and you can easily adjust the amount of friction by increasing or decreasing the wraps around the rope.
But DANG, have you ever actually tried to climb a rope with a Klemheist, especially one tied with a skinny Dyneema sling? You probably discovered that it bites down very hard on the rope, and is very difficult to slide up after you've loaded it with your body weight.
Here's a clever variation on the Klemheist hitch, where the stitching on a sewn sling is intentionally tied INTO the hitch, as in the photo above on the right.
WTF?! I learned in Knots 101 you should never do this, why would you?
Answer: for ascending a rope.
By including the stitching in the hitch, it allows enough friction for good grabbing on the rope, but also allows the knot to MUCH more easily slide on the rope when you need to move it.
Notes . . .
Works great with a sewn sling, even Dyneema (Don’t use Dyneema for a rappel backup.)
Grabs pretty well in both directions, but still holds best in one.
Easily adjustable with the number of wraps; more wraps for a skinny rope, fewer for thicker ropes or twin strands.
Some people think this is a Hedden hitch, or maybe an FB hitch. To be honest I don't really care about the name. It's more important to know how to tie it and the best applications, so let's not get distracted by lineage and whether I use the exact right term to describe it. Lots of “knot-knerds” like to argue about stuff like this. I’m not one of them.

Load transfer: The alpine block and tackle
With nothing more than a cordelette and two carabiners, the “alpine block and tackle” creates a bit of mechanical advantage that can help you move a large load a short distance.

This is part of a series of articles that cover methods to move a large load a short distance, typically to unweight an anchor. Here are two other related posts.
Load transfer: the 2:1 redirected haul
Load transfer: the stirrup hoist
If you tie your cordelette “bunny ears” style, as I recommend in this Tip, you can use it to make a low-tech block and tackle system. #CraftyRopeTrick for sure!
(History side note: The term “block” comes from the wooden blocks that were originally used on ships to raise heavy sails, and the “tackle” refers to the ropes/rigging running between the blocks.)
Climbers typically think that mechanical advantage systems only come into play in a rescue-type scenario. But there are some other situations where they can come in handy.
When might you want to use an alpine block and tackle?
In general, to move a large load a very short distance.
Maybe you're in some other kind of rescue scenario, and you need to momentarily lift a load off of a carabiner an inch or two to unclip something.
Maybe you're on a big wall climb, you screwed up your rigging somehow, and you need to lift your haul bag a few inches to get it unclipped. (Note, if you use a docking cord to attach your haul bag to the anchor, you should never have this problem.)
You have a strand of rope with a weighted knot, and you need to unweight the rope so you can untie the knot. To do this, put prusik loops above and below the knot, and rig the block and tackle between the two prusiks. See image below.
In the example shown in the video below, you can transfer or share the load in a crevasse rescue off a sketchy initial gear placement to a stronger second placement.

“The Prescription”: accident reports from the AAC
"The Prescription" is a free monthly accident report from the American Alpine Club (AAC). Learn from the choices of others.
Reading about climbing accidents isn’t very enjoyable, but it’s an important part of our education.
The American Alpine Club (AAC) publishes an annual book called “Accidents in North American Climbing”. This is available for purchase, and is free for AAC members.
However, they also publish an accident report every month on their website, called "The Prescription."
From the AAC website: "The Prescription brings you monthly unpublished accident reports, tech tips, links to new online educational resources and much more – all aimed at helping you become a safer climber."
Even better, they keep an archive of the previous monthly reports on the same webpage, so you can scroll down and read a bunch of them.
It's a free resource that can help you reduce your risk and help avoid the near misses and accidents of others, so check it out.
