Thos are also good knots to know.  Your post is value added.

I usually use three of these everyday for work. I agree what OP.

I try to remember that kt:mph is roughly 7:8. That’s generally “close enough” for estimation and easy to work with, but if I need a bit more precision 13:15 is closer. I can’t think of a situation where 13:15 isn’t going to be more precise that whatever I’m using to measure speed in the first place.



Hell yes it is.

In this vein - each colored segment on a windsock that is inflated by the wind is equal to three knots:

Instead of thinking of it as a climbing knot, think of it as a positioning knot.

For example, you have a tarp, with a ridge line.  You use this tarp wherever you camp, but sometimes trees or whatever you want to secure it to are different distances away from each other, or relative to the area you want covered with the tarp.  With prusiks secured to two corners of the tarp and wound around the ridge line, you can hang the ridgeline anywhere you want, in any conceivable orientation it's length will allow, then move the tarp exactly where you want it and set tension on it that's independent of the ridgeline's tension.

That's just one use but the most common for me.

I tied one last night, and mentioned to my wife that it was my favorite knot.

A dive into the obscura ...

Traditional climbing in eastern Germany.  

The rock is soft, and the local ethos is to use no modern metal climbing protection, instead, looping horned or handled features or jamming knots into constrictions in cracks.

Growing up, this was the stuff of legend.  Stuff beyond the wall.  Those who practiced the dark art only traveled West by rare government permit.  Mythical.

I met Mr. Uli years ago at the Engineer's School.  I can't say that I used his knot much in the last 30+ years.

Thats pretty cool.

Would need some non compressible ropes, I'm guessing. I could see this working better with old rope.
