The stick is a two-part process. First you go in, then down. I had to cut through boar hair which is pretty much like heavy, muddy, industrial carpet.
Still, when I set out to make...I originally intended to use 3/16" stock. I'm glad I didn't though...really, with a double hollow grind, top and bottom...it's a cuttin' sonuvagun. I also left enough thickness at the edge to give it a nice wide convex edge. And, as with everything, I made sure it passed the 2x4 test. :thumbup:
Thanks!
