Bow saw

Bow saws are typically available with blades of 320mm, 535mm, 610mm, 750mm or 950mm lengths (14, 21, 24, 30 or 36 inches).

The name 'Swede saw' probably derived from the ovate metal tubular frame version, invented in the 1920s by the Swedish company Sandvikens Jernverk, and additional patents by two Swedish immigrants to the US.

Traditionally, a bow saw is a woodworking tool used for straight or curved cuts.

In English and American vocabulary it denotes a toothed blade suspended between two long narrow handles called "cheeks" that are supported and separated by a thin stretcher in the center of the handles, making a wide H shape (the cheeks form the uprights of the H, the stretcher the crossbar of the H).

[3] The term 'bow saw' has also been applied to a type of chainsaw with a large, circular guide bar.
