Claim:
1. A foldable bow saw movable between a set up functional saw condition and a taken down folded packable condition, comprising: a handle arm; a top bar; a short arm; a saw blade; and a lever arm, said handle arm, top bar, short arm, saw blade, and lever arm all pivotally connected one to the other as a one piece assembly with an end of the handle arm and an end of the lever arm forming free, unconnected ends of the assembly; a fulcrum surface associated with the free end of the handle arm; and a fulcrum surface receiver adjacent an end of the lever arm which is pivotally connected to the saw blade and adapted to removably receive the fulcrum surface therein during set up and take down of the saw, said lever arm being rotatable about the fulcrum surface when the fulcrum surface is received by the fulcrum surface receiver, and said lever arm having a pivotal connection to the saw blade positioned with respect to the fulcrum surface receiver whereby, dating set up of the saw, when the fulcrum surface is received by the fulcrum surface receiver, 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 conditioned wherein the lever arm is held against the handle arm to hold the saw in set up functional saw condition, and when in set up functional saw condition, rotation of the lever arm in an unlocking direction moves the pivotal connection of the lever arm to the saw blade to an untensioned condition allowing the fulcrum surface to be removed from the fulcrum surface receiver and the assembly to be folded to the packable condition.
