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. |
