Hacksaw with blade tensioning mechanism

A hacksaw comprising:

• a frame assembly comprising:
• an upper frame member comprising a proximal end and a distal end, the upper frame member defining an axially-elongated cavity therein, the axially elongated cavity configured to store an entirety of a blade therein;
• a first handle fixedly secured to the proximal end of the upper frame member;
• and
• a second handle fixedly secured to the distal end of the upper frame member, the second handle comprising:
• a blade aperture extending through the second handle and in communication with the axially-elongated cavity, the blade aperture configured to receive the blade therethrough and into the axially-elongated cavity;
• a device aperture disposed through a wall of the second handle;
• and
• a device, wherein at least a portion of the device is configured to extend through the device aperture and into the blade aperture;
• wherein in a first blade configuration, the device is configured to retain the blade fully within the axially-extending cavity and prevent the blade from passing through the blade aperture;
• and
• wherein in a second blade configuration, the device is configured to releasably engage and secure the blade with a first end of the blade projecting outwardly from the blade aperture of the second handle and a distal second end of the blade received within the axially-elongated cavity.
