The present invention address the problem of providing a handsaw with which it is possible to dramatically reduce cutting chip clogging, to reduce the pitch between cutting edges in order to increase the surface area of the cutting surfaces of cutting edges known as "Uwame" (third facets), and to obtain a low cutting resistance and excellent sharpness. The handsaw has a plurality of saw teeth arranged along the lateral edges 21 in the longitudinal direction of a saw body 20, wherein the saw teeth comprise a combination of crosscut teeth X having a triangular prism shape or a trapezoidal prism shape and rip teeth Y having a parallelogram prism shape, and wherein the respective prism teeth constituting the crosscut teeth X and the rip teeth Y are configured such that a rising angle θ, relative to an edge surface 21a, of the lateral edges 21 in the longitudinal direction of the saw body 20 is the same for at least adjacent prism teeth, thereby configuring a gap S between the respective adjacent prism teeth to be constant in the rising direction of the teeth.
The present invention addresses the problem of proving a handsaw configured so that clogging with chips is dramatically eliminated, the teeth can be densely arranged without widening the pitch of the tooth tips, the top cut surface of each of the teeth, which is called a "top edge", can have a large area, a reduction in the cutting performance caused by the clogging of chips can be sufficiently prevented, and the cutting performance of the handsaw is significantly improved. A handsaw is formed by arranging saw teeth at a longitudinal side edge (21) of the saw blade (20). The saw teeth are formed as prism-shaped teeth (30) which are configured in such a manner that at least adjacent prism-shaped teeth rise at the same angle (θ) from the edge surface (21a) of the longitudinal side edge (21) of the saw blade (20) to cause the gap (S) between the adjacent prism-shaped teeth to be constant in the direction in which the teeth rise.
