Abstract
A spear for hunting frogs, the spear being made from a straight length of drill rod, which extends from one end of an elongated wooden handle, the protruding portion of the drill rod having its outward end flattened on both sides and tapered towards a barbed point, the point being heat treated and oil hardened so that the point will remain sharp even though being subjected to striking against rock and the like while hunting frogs out of doors.
