Abstract: A hacksaw may include a blade support frame, a handle operably coupled to the blade support frame at a first end of the blade support frame, a movable blade engagement assembly and a multi-function fixed blade engagement assembly. The multi-function fixed blade engagement assembly may be disposed at a second end of the blade support frame. The multi-function fixed blade engagement assembly may include a first clamping structure to affix a first end of a blade to the hacksaw via an engagement pin and a second clamping structure to affix a portion of the blade spaced apart from the first end to the hacksaw via a clamping or pinching force exerted on the portion of the blade. The movable blade engagement assembly may be operably coupled to the handle and to a second end of the blade. Tension on the blade may be adjustable by adjustment of the movable blade engagement assembly.

Abstract: A hacksaw blade may include a first end having a first mounting orifice, a second end having a second mounting orifice, a first side face extending from the first end to the second end, and a second side face, opposite the first side face and extending from the first end to the second end. The blade may further include a top edge extending from the first end to the second end between the first and second side faces, a cutting edge disposed opposite the top edge and including cutting teeth disposed thereon, and a tension focusing slot disposed between the first end and the second end, and spaced apart from each of the top edge and the cutting edge. The slot may be formed by material removal from at least the first side face.
