I made a weapon out of 8mm (5/16's" TVP), which isn't on the market yet. I'll attach a photo. I used a class 2 splice. I use it on Tachyon on a regular basis.
I had this cord 'break tested' with an eye splice in each end. It broke at 33.28 kN (7,481 lbs).
Is this the one you showed us before, that broke in the eye? How is this possible when the cord in the eye carries only half the tension? Very strange...
