I think this is the best of the bunch of small pocket knives you can carry. The sissors cut most anything from paper to fingernails to small wires quite well and the knife blade can be kept very sharp. The fingernail file is not too useful except as a small screwdriver. The removable tweezers and pick work well also. It comes with a small key ring which barely can hold one key, but you really need a small chain to keep it with several keys.
