 And basically what we did with that, we put a sharp belly on the blade for added cutting power. And we did a radical change of the grip to blade angle. So with the hand in a normal locked wrist position, that gets much more flesh and bone and body mass behind it, whether it's a thrust or a slash. Don't cut yourself, Dave. I'll try to leave my appendages, you know, where they're at. So how did that come about?
