It is a rough tool that can be used for cross-cutting branches or firewood, up to a log diameter of half the blade length, limited by the height of the frame above the blade. 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 Sandvik, and additional patents by two Swedish immigrants to the US. Modern versions all share those common features.
Traditionally, a bow saw is a woodworking tool used for straight or curved cuts. A bow saw is a type of frame saw. Its thin blade is held in tension by a frame. 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). The blade is kept in tension with a turnbuckle or a twisted cord that runs parallel to the blade between the two cheeks but on the opposite side of the stretcher. If a cord is used, the cord is twisted with a toggle attached to one loop of the cord, adding tension. The toggle hits the stretcher, which keeps the cord from untwisting. A finer version of the saw uses a narrow blade of a or less, with handles that allow the user to hold the saw and turn the blade. In this context it is also known as a turning saw,Wood, Harry Einsley, and James Henry Smith. Prevocational and industrial arts,. Chicago: Atkinson, Mentzer & company, 1919. 9.
