What are you going to saw? None of these tools is going to lay in a cord of wood for a winter camp. The small saws on multi tools are very good at making precise notches for deadfalls or for lashing paracord to poles when you want a little more finess. the wire saw's strength is in it's compactness and manipulation. If you had to disarticulate a large game animal, they are good for getting into cartilagenous tissue and awkward cuts requiring flexibility.
