A handy dandy multi tool - Leatherman OHT Multi-Tool - One-Handed Opening, 16 Tools in One

In my line of work I need to use something like a multi tool a few times a day. So far the OHT has performed well, especially in terms of one handed manipulation. The pliers and tools are all easily accessible and lock into place firmly and the spring loaded jaws can be a lifesaver. The extended shank on the Phillips head is fantastic although the other drivers are of a noticibly shorter length. The blades come reasonably sharp The tip of the knife is very thin, although I haven't been able to break it yet. Overall, it does everything I need it to.
