Not for making a sandwich, this knife has only one purpose, keeping you safe when the time to talk is over. The T shape of the handle makes this type of knife very very difficult to dislodge from the hand and is a sought after design for this reason. The blade is hand forged from an old file and is sharp on both edges. The handle is a sculpted piece of Minnesota walnut with a brass pin passing through. The tang passes through the handle and is hammered tight to the butt with a steel washer. Tough as nails. The buyer is responsible for following local laws regarding this type of blade and they are prohibited in some places.
