I recently had the opposite experience. I tried to take the handle off my Becker with a Leatherman Squirt knockoff (Cabelas brand). The screwdriver twisted like a corkscrew before slipping off the screw head entirely. I got the real Squirt out and it came right off. I'd say go ahead and use a knockoff if you want but make sure you test it first to make sure it holds up, because obviously some are better than others.
