I'm pretty good at sticking Ka-Bars, bayonets, and machetes. I never found a throwing knife that I liked. They are all too light and too short. I have broken eveything from Ka-Bars to a Gerber Mark II by throwing them. I have a Cold Steel thrower that isn't too bad, but I can stick a machete easier. Maybe its because I use the blade hold, I don't know. The knife has to turn 180 deg from my release to the target. Somehow I can sense that better with a big knife.
It hits harder, too.
