In reading knife reviews from users at various sites (like Amazon, etc) there will be an occasional complaint about a folding knife opening unintentionally in the users pocket, and resulting in some injury.
So far, that has never happened to me, but I do wonder about the safety of some of my flipper knives and assisted knives.
Ever had a bad experience with a folder in your pocket?
I had a Kershaw blur tanto serrated that opened in my front jeans pocket. Those blur assisted only need a soft nudge to get it to open I must admit. There was some other stuff in there which have set it off and its pointy tip tore out part of the pocket and my thigh too. Nothing serious but it did bled somewhat. I stayed away from it and have since sold it off. I am extra careful not to mix stuff with any folder that I edc. Its even better if the folder has a sheath.
