That looks similar to a Beal Jammy. My question is the Beal Jammy Heat resistant? If I tried that knot with a Jammy on a DRT am I gonna burn thru it? The smaller diameter makes me a little more skeptical. Web site says it has a heat resistant jacket. But not sure what that means.
It’s the middle length Jammy, about 20”, I took the plastic cover off for some reason. It has a Kevlar core, heat resistant, and nylon cover, not heat resistant, they offer a version of cord, not loop, with a dyneema core, with a break strength of 18kN. The Kevlar cord has a break strength of 15kN.
The first Knut H was a double eye hitch, top in picture below. The bottom one is tied with the end of the rope, next one up shows the same tying, but with the Jammy, next one is like the last, but uses the second eye to become a double eye hitch, called the Enzyme, discovered by someone else.
