A two-position, quick-change hacksaw consists of a back member, handle structure adjacent a rearward end portion of the back member, and a swing arm adjacent the forward end. The free end of the swing arm and the forward end portion of the back member have coplanar blade-engaging elements thereon which serve to engage the forward end of the blade and which are commonly disposed on an arc that circumscribes a third coplanar blade-engaging element disposed on a coupling block of a tensioning mechanism for mounting the rearward end of the blade. Two coplanar sets of transversely paired engagement elements enable mounting of the blade both in a plane parallel to a medial plane of the frame and also in a plane disposed at a substantial angle thereto. In one configuration, with the swing arm in its inoperative position, the saw is adapted for cutting within a relatively confined space; with the swing arm in its operative position the saw is configured for cutting within a relatively unconfined space.

A low profile hacksaw comprising an elongated blade having a cutting edge. A rigid I-beam frame member has a forward end portion and a maximum height portion. Preferably, the maximum height portion is located at the rear end of the frame member, but it may be located intermediate the forward and rearward ends. The frame member has an arcuate portion which extends substantially the entire length between the forward end and maximum height portions and which curves downwardly and forwardly towards the forward end portion to provide the hacksaw with a low profile. A manually engageable handle is provided for manual grasping to enable performance of a cutting operation wherein the cutting edge of the tensioned blade is engaged with a work piece and moved forwardly and rearwardly to cut through the work piece. A releasable blade tensioning device provides a second blade mounting structure on which the other longitudinal end portion of the blade is removably mounted. The blade tensioning device is constructed and arranged to affect relative movement between the first and second blade mounting structures to tension the blade in the longitudinal direction thereof and thereby apply a rearwardly directed force to the forward end portion of the frame member. As a result, the rearwardly directed load applied to the forward end portion creates a bending moment which is distributed throughout and resisted by the frame member as a result of its curvature and I-beam configuration.

A hand saw scabbard seats the saw blade of the hand saw with the handle at one end abutting its open end. The elongated molded scabbard has a generally rectangular cross section formed by spaced face walls and relatively short side walls extending therebetween and an end wall at one end thereof. The other end of the housing is open to provide the entrance into the cavity which is dimensioned to seat the saw blade. The inner surface of at least one of the face walls has integrally formed bosses thereon which bear upon the surface of the saw blade seated in the cavity to frictionally retain it.
