on the subject of crowbars again: how big does one need to be to be much use. can you prise open a locked door with the little ones. and i know people sneer at the super tough knives as 'sharpened pry bars' well are they? if i try breaking a chain with one am i going to end up with a razor sharp knife half in the face?
i keep thinking of the people on 911 who were stopped getting to the roof by a lock and the cleaner who got a bunch of people out by cutting through an interior door with his squeegee. in an urban environment it's going to have to be something pretty dramatic to be a disaster scenario; so rubble, jammed doors, or prising yourself out of a lift or vehicle don't sound that unlikely. is there some other solution than prying?
