A bowstring which is attached to a recurve or other long bow providing a section having an abrasive circular margin used to cut wood or other substance in an emergency replacing the bowstring of the bow utilized for shooting an arrow.

A foldable bow saw movable between a functional saw condition and a folded packable condition includes a handle arm, a top bar, a short arm, a saw blade, and a lever arm, all pivotally connected one to the other with an end of the handle arm and an end of the lever arm forming free, unconnected ends of the assembly. The free end of the handle arm includes a connecting fulcrum surface adapted to removably mate with a fulcrum surface receiver in the lever arm. Rotation of the lever arm in a locking direction about the fulcrum surface moves the pivotal connection of the lever arm to the saw blade to a tensioned functional saw condition. Rotation of the lever arm in an unlocking direction allows the fulcrum surface to be removed from the fulcrum surface receiver and the assembly to be folded to the packable condition.
