ABSTRACT:
The survival device is useful as a trenching tool, storage container, cooking and eating utensil, shoe horn, spade, hoe, grappling device, spear head, and the like. It includes an elongated hollow, tubular body with a detachable head bearing an elongated shallow dish-shaped blade. The blade is pivotably connected thereto for movement between a resting position along the side of the tubular body, an intermediate lockable position extending laterally 90.degree. from the tubular body and a fully extended lockable position projecting forwardly of the tubular body in line with the length thereof. A locking plate interconnects the blade and head and is pivoted over a cross bar in the head. The locking plate has spaced notches in its periphery engageable with a cross pin to hold the plate and blade in the desired position. A locking ring may also be provided around the head. The tubular body may be split longitudinally and provided with a slip tightening ring so that the tubular body can be releasably secured over the end of a stick to use as a spear or knife. The head can be removed and replaced by a fish filet knife blade. The rear end of the tubular body can be threaded to receive additional storage tubes. The device is light weight, durable and efficient.
