Ok, I got two for the mix. I also have a Roach Belly design, but I heard that one didn't go over well last time.
#1 is a camp knife based on the cutlass machete. The blade widens as you move from the ricasso to the tip. This is primarily for extra belly, though it'll help with chopping also. The balance point should be right at the choil.
1/8" or 5/32" O-1 steel, 1.75" tall at widest point
6.5" Blade, 4.5" Handle, 11" OAL
Convex saber grind (could be wider)
#2 is my bushcraft tanto. I call it the Bush-Ido. The handle could be lengthened a bit, cuz I have little hands. The point of balance could also be more neutral, say between the ricasso and first pin.
1/8" O-1 steel, 1.25" tall
5.25" Blade, 4.25" Handle, 9.5" OAL
Convex saber grind
