I think there are two very distinct classes of tiny/keychain tools. There are those you get free with company logos and at the checkout counter and then there are the ones like the little leathermans that are decent quality. A good example is the leatherman squirt EL, the wire strippers on that are great compared to most wire strippers from places like radio shack and the big hardware store, I think because the "blades" overlap like scissors instead of just meeting and the fact that they are a better grade of steel.
