An unusual profile to both blade and handle there Jie. A good looking knife though! What is this "gear" thing about? Does it serve some function other than making a clicking noise?
See here for a bit more info on the original navaja. http://en.wikipedia.org/wiki/Navaja
Blade profile looks like a boat. First thing I said when I first saw the prototype, first thing I said when I first picked it up, and it's the first thing I think when I see it now.Sweet knife though, no doubt. Very nice, Jie. If it were like... 2/3rds the size I'd be all over it, but I've also got very small hands.
