The preferred choice of a multi tool and/or a knife may depend on how task oriented a person is. I carry a small multi-tool (Leatherman Squirt P4) on my keychain in the left pocket and and a Microtech OTF at the ready for all sorts of tasks for my strong hand. The Microtech is a one-handed operation 3'5" blade knife and I use it as a utility knife all the time. I don't use the blade on my Leatherman very often, but I do use the pliers and file quit often.
