evry time a knife has come open in my pocket its either a funky design (ie spyderco khalsa which is tip down FWIW) or the detent was bad, i EDC tip ups and have for probably 10 yrs now and other than the reasons stated above never ever a problem, i mostly carry emerson or strider now, occasionally a spyderco Ti ATR, and all stay closed just fine.
i dont like tip down myself, i have a lot of very nice tip down knives which never see any use (ie crawford ti kasper and perfigo, MT SOCOM elite w/a brend grind blade, ralph maxx X2) because i simply dont like the tip down carry.
gravity is the reason knives have detents to hold 'em closed.
