Thanks everyone for your help, and just to say the prying isn't anything serious, just like prying open a can or something minor. Thanks!
Flathead from an SAK then, maybe. If you need a tin opener, it's there, too! It's why I carry one.
Granted, a tough folder will cut through and open an average aluminium tin or pry open a tin of paint easy enough, again, I see no point in worrying these when there is perhaps a more appropriate tool. All that wear accrues. If not in the blade edge, then the blade steel structure itself, the pivot, the lock.
