If you've ever used a Prussic on Amsteel, you've probably noticed that they slip... a lot. Heck, if you've actually tried to tie a Prussic using Amsteel, you almost certainly know that it doesn't grip at all, and just slides up and down like a hilarious miniature zipline.
Well, about a year ago I came up with a hitch (whose closest known hitch with a name would have to be the "Magnus Hitch") that grips flawlessly on virtually all "slippery cord" types.
Better still, you can tie it in-line on a single length of cord (unlike a Prussic which requires a separate length of cordage).
It's not just useful on "slippery cord" either, and I use this on all of my guy lines. If you place the adjustable loop this hitch produces on one end of the guy line, then you have a finite adjustment to 50% of the length of the cord itself. If you're attaching both ends of the line inside a fully-opened loop, then you can adjust it down to less than an inch between the two anchor points.
Basically: you can use it however you want.
I've uploaded this video showing how to tie it (deliberately using Amsteel to demonstrate that it does actually grip onto itself perfectly):
Just want to be 100% clear that I'm not sharing this to gain subscribers or view count (there's no point, I don't get paid for any of those pointless numbers anyway).
Another thing to add that wasn't mentioned in the video: Instead of doing the final "lock-off knot" as shown in the video, you can take the excess on the working end and tie two half-hitches on the outside of the loop, which adds even more grip. Be careful, though, because you might just add so much grip that you can no longer adjust the line!
Hope you find it as useful as I have.
All the best,
Simon
