i recently switched from the Gerber Multi-tool to the Leatherman Wave. I really like it. You can access the knife and saw blades without having to open it up, all the small tools lock in to place. and the tool has gentle lines, so it is comfortable to use in your hand. It has a small bit driver with a "flipable" phillips/stright screwdriver. they do sell accessory packs with replacement bits for different sizes/shapes of drivers.

I personally like the pliers. I do tend to use them, and in a pinch could make a very nice defensive weapon. Sure you could stab them, but what if you want to detain them? How about a nice pinch of ear with the pliers? They wouldn't be going anywhere.
