Abstract: A collapsible saw comprising an elongated hollow frame member, a handle pivotally connected to the frame member by an interconnecting member to form an angle with a saw blade connected between the free end portions of the angle, and a lever pivotally attached to the free end portion of the handle including a device for engagement with the saw blade and arranged to hold the saw blade by means of toggle action. When the saw is in the position for use, the handle and the interconnecting member abut the frame member at a distance from the point of attachment for the interconnecting member. The saw thus combines a rigid structure with rapid engagement of the saw blade.
