Microtech Triangle Wrench

This is a hand tool for the triangular security bits used on some Microtech OTF knives. Depending on the material you use, it may not survive more than one use since there's not much room to work with in the 5mm recess the screw sits in. Fortunately, the walls of the recess will help hold the tool together while using it.

These screws are only meant to be finger-tight to begin with, so this is not a screwdriver "bit". This is the entire tool.
