Abstract
A knife has a fixed blade, a plastic base fixed to the tang of the blade, and a rugged rubber grip fixed to the plastic base. A visible portion of the plastic base extends along a back of the knife and also forms a hilt and forwardly swept guard. A visible portion of the rubber forms a grip along the bottom and sides of the handle, and also a thumb rest along the top of the handle at the guard. The handle is formed by injection molding the plastic to the tang of the blade, and thereafter injection molding the rubber to the plastic. The plastic base has features thereon for ensuring that the rubber is strongly fixed to the plastic. The base and the grip are made of strong, tough, damage-resistant materials.
