You know, of course, that the 400-600 breaking strength Zing It is overkill for the purpose. But, you'll never need to replace it, tough as it is.
I'm not supposed to be able to, but because I didn't know better, I just opened up with a darning needle some supposed spectra / dyneema (tm) hollow braid throw line of 1.25mm diameter, undeterred when I encountered a core of straight strands of the same material. The needle slid along side of those strands. So, unlike AaronAlso, I was able to make up a bunch of knot-free spliced loops for Prusiks.
Once I got the hang of it, I made a few dozen, using just a few $ of material. They grip just fine.
But when all is said and done, ITW makes some terrific nylon plastic bits for this purpose that only require one hand to operate, not two. If they're designed for military use, they're not likely soon to fail.
Last winter the fingers of at least one painfully cold and wet hand would rather have been in a warm and dry pocket than working nice tight, wet, and cold prusiks on tarp line and tie-outs in a snowstorm.
