I find myself in need of common little tools while "in the field" from time to time, and was wondering if anyone could recommend a high-quality, compact, keychain-size multitool. I have a leatherman type tool, but it's too bulky to keep on me all the time, plus the 4" lock blade on it makes security/police anxious (technically it's legal to carry this in my community, but they don't seem to care about that). I most often have to screw/unscrew stuff (phillips and flathead), open thick cardboard boxes, pry small things apart/open, open bottles/cans. I don't want to get something made of cheap, soft metal that'll wear away quickly.
Any recommendations?
