I've got a Gerber suspension that I use for work, not bad at all for £25, and I'm not too arsed if I lose it at that price. I broke the pliers on it a couple of years ago, and Gerber sent me a new one out without question!
Still got one of the original leatherman tools I bought in Bosnia circa 1995 that comes out with me as it hasn't got a lock blade.
Lock knives are a big no-no in the UK, don't get caught carrying it!
