My only incident was with a ZT 0350. This is a spring assisted flipper, so it is begging to cause trouble. I stuck my hand in my right pocket and was thinking, "ow, what the heck is hurting me". :eek: It was tip up, and (here is the key factor) over to the left side of my right pocket. Now if you carry a tip up knife sort of parked against the right edge of your right pocket (all due apologies to you lefties), then the likelihood of this sort of thing drops significantly. And if your knife isn't spring assisted with a marginal detent, you are better off yet again.
It is a liner lock, which sorts of gives the excuse to wedge this story in here, but to be perfectly honest that really has little or nothing to do with it.
But this could never happen with a Spyderco knife, just one of those evil ZT jobs.

Don't ask me what got me to buy a spring assisted flipper, it was sort of an impulse buy at a local shop, but that is another topic altogether.
Nonetheless, there is a lesson in all of this, namely if you carry a tip up knife, park it in your pocket so the blade is against the side of the pocket. If you carry IWB, via con Dios.
