[Collin Stiers]

I recommend the Leatherman wave, but more generally any Leatherman that accepts the Leatherman bit type, Then you can buy the bit set, and have any type of bit you will generally ever need for robotics in you pocket or on your belt, most people on my robotics team have this knife and we all love it, it has most any tool you will ever need, from screw drivers to wire cutter/strippers, and pliers. Great tool, never had any problems with it
