From BudK. It was advertised in the American Rifleman. Since it was there, i figured it wasn't cheap chinese stuff although it is made in China. Sort of a contradiction but it's well made. It arrived a couple of weeks ago. It's licensed by the Marines. I compared it to the one from WW2 and it's just a little different. They don't do a thing for me since they seem a little old fashion. If I want a heavy duty knife, I usually go with Cold Steel.
Anyway. If you want a heavy duty knife licensed by the Marines and it looks a little better than the one I have from a guy who fought during WW2 and saw action in the Pacific, BudK has them for 19.95.
