When I was 12 or 13 years old, I bought a Buck 112 and used to snap/ flick that thing open all the time. This beat the heck out of the pivot pin and the blade got all sloppy and loose after a year or two. My dad wouldn't let me mail it in to get it fixed, but he did help me put a new pin in the pivot, he was a machinist back then. I also used to pinch the blade and do the handle drop opening technique, until the knife got away from me one day and I got a nasty cut. In the end, it's just a tool, use it however it pleases you.
Eventually I grew up, and realized that if I needed a one handed knife, carry a one handed opener designed as such.
