Here is a scenario for you. You are in deep in the forest without the proper tools, and all you have on you is the Commando Wire Saw. You are in better shape then you might think. It is small enough to fit in your pocket and strong enough to cut wood, plastic, bone, metal and most things you may encounter.
Carried on the person or in a survival kit, wire saws can be a very precise tool if used correctly, they can cut objects that normal saws are too thick for as well
