I use his kerambit for training, and sometimes I carry it too. There are no kerambits sharper than his. Very slim, very low profile, it's almost perfect. The thing that kinda worries me is the blade thickness. It's very thin, and while it's scary sharp, I'm worried that it would break in a SD situation. And also, the handle is considered small. I have small hands so it's perfect for me. Not for those who have big hands.
