It will only open if it is held in a certain way, then you push down on the blade and it releases, has to
be help tip down if I remember right. I have a mint one (like alot of guys here) and I think I paid $6-8
for it on eBay last spring. They are really neat little knives, for $10 - and the blade is full on this one,
they were just built with a blabe that looks too short for the frame, must have something to do with
the trick opening mechanism.
