This famous Lirakis tool could be the best all-around knife we've ever found. The knife blade is extra heavy duty with a shackle key built right in. Stainless blade takes and holds a good edge. Rosewood handle has a solid brass bolster, and the knife tip is designed to work as a functional screwdriver tip. Lanyard included for one-handed access, and the sheath is made of rot-proof nylon webbing.
