There would be a bit of interest I reckon in a Bussekin Competition Cutting knife...I checked out the sport and thought it quite interesting...SR101 done by Dan with a Res C grip would be perfect. I bet there are a few guys here who could do quite well at that! Flat grind SR101 10 inch blade tapering to 22thou at the edge and hardened to 61 Rc which would need to be convexed but thin...sell them on the basis they are specific for the sport and not for the "Cinder Block" stuff...and I think a few Dogs/Hogs/Rats might give this a go...hell I would if I was in the US....infact I might even come over to try this if the holiday fund allows! Doing one of the recognised courses would be an interesting time regardless!
