TSS... I get what you're saying about getting cut but you have a lot more control with a pad or something... When I started I used a pair of old welding gloves then as I got more confident I started using just a leather pad... You could build one of those contraptions in the TBB III with the copper pipe or get some "no cut" (Kevlar) gloves that the police use.
Based on kelvar rope, broken glass, and chainsaws, I am going to say I don't trust any fiber for preventing cuts.
I do trust leather though, I use a small piece as a cutting pad.
But I totally agree with you about leather pad. Time will help me. I need to take a vid of my knapping so you guys realize how I am doing this.
