Abstract:
1. A hand-held saw, comprising: a unitary single-piece saw frame having a proximal end and a distal end, wherein the unitary single-piece saw frame has a top side, a distal side connected to an end of the top side, and a proximal side connected to another end of the top side; a first saw blade coupling device disposed at the distal end of the saw frame; a second saw blade coupling device disposed at the proximal end of the saw frame, wherein the first saw blade coupling device and the second saw blade coupling device is each adapted to securely couple a saw blade to the saw frame; the saw blade securely coupled to the saw frame at the first saw blade coupling device and the second saw blade coupling device; and a handle coupled to the proximal end of the saw frame, wherein the handle is oriented such that a handle axis defined by a length of the handle is aligned with a cutting axis defined by the first saw blade coupling device and the second saw blade coupling device, wherein the unitary single-piece saw frame consists of only one unitary member, wherein the unitary single-piece saw frame has a plurality of through openings formed therein, wherein the plurality of through openings formed on the unitary single-piece saw frame comprises: a first through opening formed at a corner between the distal side of the saw frame and the top side of the saw frame; a second through opening formed at a corner between the proximal side of the saw frame and the top side of the saw frame; a third through opening at the distal end of the saw frame; a fourth through opening at the proximal end of the saw frame; and a fifth through opening at the top side of the saw frame, and wherein each of the plurality of through openings extends, along an axis perpendicular to the cutting axis, through the thickness of the unitary single-piece saw frame.
