Hacksaw with handle tensioning mechanism

A hacksaw comprising:

• a blade support frame;
• a handle operably coupled to the blade support frame at a first end of the blade support frame;
• a multi-function fixed blade engagement assembly disposed at a second end of the blade support frame, the multi-function fixed blade engagement assembly including 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;
• and
• a second blade engagement assembly operably coupled to the handle and to a second end of the blade.

A hacksaw comprising:

• a blade support frame;
• a handle operably coupled to the blade support frame at a first end of the blade support frame;
• a fixed blade engagement assembly disposed at a second end of the blade support frame;
• and
• a movable blade engagement assembly operably coupled to the handle and to a second end of the blade,
• wherein tension on the blade is adjustable by adjustment at the movable blade engagement assembly and corresponding linear movement of the movable blade engagement assembly,
• wherein the movable blade engagement assembly comprises a rotatable member operably coupled to a tensioning rod, and
• wherein the rotatable member is disposed at a distal end of the handle and is disposed in a cavity formed in the handle and is surrounded on at least four sides by a portion of the handle to interface with the tensioning rod to change tension applied to the blade via rotation of the rotatable member.
