Right, so I'm in Switzerland for the summer and I've been given a Swiss Army Knife as a gift. The knife in question is this one: http://www.victorinox.com/product/1/100/1004/1107/0.9023 The large blade is about 3 1/8 inches long with the cutting blade maybe about 3. I know in the UK you are allowed to a pocket knife with a blade of less than 4 inches. The issue is that the blade locks open to prevent it from closing on your fingers while in use. I've had a search around the interwebs and there seems to be some disagreement about the method of locking. Some say that since it's a positive lock (i.e. keeps it open rather than preventing it from opening) it's legal. The argument was that if the blade can't be flicked out or fall out with gravity then it wasn't a locking blade. Although that seems questionable to me. Question 1: What is your take on this? I know there are some bit-techians that are also police officers in the UK so I'd be particularly interested on what they say. When I get back to the UK I don't intend on carrying it everywhere I go, probably to Uni (handy to cut and strip wires, screw things in/out etc) and camping trips etc. It's not like I'm going carry it around when I go out to a bar or anything. The other question I have is this: The locking mechanism is basically a little plastic slide which prevents the blade from closing. If I were to remove dremel this plastic slide (therefore removing the locking ability) I would assume it would then fall back onto the right side of the law?
