Thanks for the input guys, i really appreciate it.
I'd like to hear from anybody that uses a blade even if it's just to prune backyard foilage.
Also, i will post pictures when the prototypes get more finalized.
I lean towards 01, D2, or 1095 tool steels just because i've had good success hardening them. I personally like REAL hard blades and since i've bent more then broken under test conditions. They also take a good and durable edge. Plus, they are reasonably priced and my goal is to price them out at an affordable level. I might even make the grip with a ParaCord wrap and make Micarta an option.
I'm looking at a 5-6" blade, 1/4" thick with more then one type grind for different purposes.
