Claims5
A hand saw comprising
- a straight, hollow, tubular handle, one end of the handle being collapsed to form two closely spaced parallel walls with a slot cut through the handle at adjacent edges of said walls and aligned with the space between the walls,
- threads provided on the other end of the handle to enable a handle extension to be secured thereto,
- a straight band saw-type blade with teeth along one edge, narrower than the parallel walls so that the blade is fully confined by the handle to the very end of the handle at the collapsed end, said blade also having one end disposed between the closely spaced parallel walls and with the teeth of the saw facing the slot, said blade being axially aligned with the handle so as to form an extension thereof,
- and a pair of set screws mounted in one of the parallel walls and bearing against one side of the blade to releasably retain the blade on the handle.

A hand saw comprising
- a handle having a straight, hollow, tubular body circular in cross section, one end of said tubular body being collapsed to form two parallel walls with a slot between them very slightly wider than the thickness of a blade to be carried by the handle,
- a slit in the body aligned with one edge of the slot to provide access to the slot from one side thereof, said slot also being open at said one end of the handle and said handle being suitable for storing blades inside its tubular body,
- threads provided on the other end of the handle to enable a handle extension to be secured thereto,
- a straight band saw-type blade with teeth inclined toward the handle along one edge and having a portion of the blade disposed in the slot with the teeth of the blade facing in the direction of the slit, said blade being axially aligned with the handle and with a portion of the blade extending into the circular portion of the handle and the working end of the blade also extending out of the handle through the open end,
- the height of the slot being greater than the height of the blade and the slot being closed at the top to prevent the hand of the user from engaging the blade when the handle is gripped at that end and force is applied on the handle in the direction of the teeth of the blade,
- and a pair of set screws in the body extending through one of the walls to bear against the blade to hold it in any selected position in the slot of the handle.
