After many requests for a larger version of my Bushcraft knife, I came up with the BushMaster. 10″ long overall with a 5″ blade and 5″ handle – it is probably the most capable knife I make and that is why it is at the top of every page. I started this knife in 2008 and it has been a consistent seller with amazing feedback. Much care was put into getting the balance *just right*. I use 1/4″ thick material for handles because it is taller top-to-bottom than my bushcraft knife and has a little more palm swell. This knife features a full flat grind with a larger/deeper set of thumbgrooves. Corby pins and a lanyard tube keep the handle on tight and make this a nearly indestructible knife. Feel free to work this knife as hard as you want. Break it? I’ll replace it FREE of charge.

5″ of 3V steel, hardened to 59-60 HRc, 0.22″ thick, Flat grind, Brushed finish on flats, satin-finish on grind, small guard, thumbgrooves, spine rounded at handle front
