Could you all just google "gravity knife"? Does any of the knives shown in the google result look any similar like a spyderco military or paramilitary? -No!!! A gravity knife is a complete different type of knife than a one hand folder. I can't believe that people still think they can change the type of knife by loosening or tightening the pivot. Tight pivot=legal, loose pivot= bad gravity knife WTF??? Come on...
Actually some states consider a knife that will not hold closed on its own a "gravity knife". For example, in my state of Ca, if you shave off the ball detent on a liner lock you have now created a gravity knife. Yes, it sucks, but that is how they play.
