How to Tie a Frost Knot to Start an Etrier or Join Webbing - ITS Knot of the Week HD

[@simonforget280]

Frost bites or Frost knots are simple, efficient and secure but almost unknown by the vast majority of people. I haven't been able to confirm if they retain these qualities when used with rope or cordage, as opposed of webbing. For your information, your pronunciation of "Etrier" is fairly right, way better than other non-native French speaking folks that aren't able to deal with the second syllable (e-tri-er). More accurately, the first "e" have an acute on it, making it "é". French people that have learned English as a second language (as myself) tend to omit any accentuated characters when writing in English since computers setup for English folks aren't able to deal nicely with these most of the time. This is at least one good justification to use Unicode now on. :-) Keep on your good work.

Simon the frost knot doesn't work well with non flat material. I am a certified rope rescue technician instructor and we teach the frost knot slightly different using only one section of webbing tied folded in thirds with frost knots at both ends and then use those to attach a basket litter to a bridle for vertical lifting of victims.

how much tag end do you want to leave in the middle of the frost knot exposed?

Is there any advantage to tying a frost knot instead of just a water knot? As max pointed out it looks like the frost knot uses more webbing. I am am part of a local low/high angle rope rescue team with my local fire dept. and would be interested in using this knot as pointed out below by max.

Not many people know, but there's a concept of courtesy rigging which is used to extend webbing on rappel starts where the rappel start is far from the anchor. In those instances rope pull is an issue. The reason you'd want frost knot is simply because, you end up creating a loop where a carabiner can be clipped into to extend the webbing.

At least in the areas I climb, webbing is most commonly used as rappel anchors around trees, and the standard / best practice (at least locally) is two leave two rappel rings or quick links to pass the rope through (sometimes ice climbers or people bailing will omit the rap rings and just pass the rope against webbing- probably fine for single use, but obviously this would be terrible and unsafe for repeated use). The water knot makes it very simple to put rap rings inside the loop. I don't know if it's even possible to do that with a frost knot, but if so it would be much more complicated. Installing quick links would be fine of course, but rap rings are much cheaper and lighter, so many climbers carry those in their bail kit. With the water knot it's also very easy to replace worn-out webbing or cord on existing tree anchors. For example if you're leaving one good piece of cord or webbing and cutting off the rest of the tat, you can easily leave the existing loop, pass the fresh webbing through the rap rings or quick links, and match the length of the existing loop by adjusting your water knot.

We make hasty harness and diaper harness with these webbing

Why not tie a water knot and save some webbing?

If you are making an etrier/ladder, the frost knot creates a small loop that can be cliped with a carabiner to anchor the ladder. The water knot could join the webbing at both ends but not make a small loop that can be anchored.
