For fabricating snare triggers. My favorite, if I only had one knife/tool, is my Swiss Army Fieldmaster. The only glitch is not having needle nose pillars and a wire bender (Leatherman/Gerber). I've picked up several (damaged packaging) <$20. What I like about it is it's lighter than a multi-tool and less expensive. Between the saw, awl and dual blades I can fashion 90% of the known triggers for snare-traps. Total MacGyver camping.
