Great thread topic. I’m looking forward to your results.
I want my folding knives to work well as defensive tools. For me, this means:
1. Symmetric or reverse angled grip. Must be ergonomic in tip up edge in, and tip down edge in grips.
2. Blade shapes that work for thrusting and cutting, especially in the Pikal applications.
3. Good grip texture that isn’t slippery when wet.
4. Ambidextrous clip placement (R/L carry, tip up).
5. Rapid and consistent deployment. Stud, flipper, wave are all good.
6. Rugged blade that won’t be ruined by a drop on to a hard surface.
