Provided is a handsaw with good cutting performance that ensures a smooth cutting operation and can apply sufficient incising pressure of the saw blade on an object to be cut at any position from the near side to the tip side of the toothed section. The saw teeth 30 of the handsaw each have a vertical cutting edged flush lateral face 31 that rises alternately in flush with one surface and an opposite surface of the saw plate and has a front vertical cutting edge VE1 and a rear vertical cutting edge VE2. Each saw tooth 30 also has an obliquely cut end face 40 at its tip end. The saw teeth are configured such that an incident angle α of the front vertical cutting edge VE1 of each saw tooth 30 with respect to a tooth point line L of the saw increases gradually from an onward stroke beginning side 21a to an onward stroke end side 21b of the toothed section 21.
A handsaw having in a toothed section a plurality of saw teeth rising from an edge surface in a longitudinal direction of a saw plate, each saw tooth having a vertical cutting edged flush lateral face that rises alternately in flush with one surface and an opposite surface of the saw plate, each vertical cutting edged flush lateral face having a front lateral edge located in front in an onward direction of the saw serving as a front vertical cutting edge and a rear lateral edge located at rear in the saw onward direction serving as a rear vertical cutting edge, each saw tooth having at a tip end an obliquely cut end face obtained by obliquely truncating the tip end, wherein the saw teeth are configured such that an incident angle of the front vertical cutting edge of each saw tooth with respect to a tooth point line of the saw increases gradually from an onward stroke beginning side to an onward stroke end side of the toothed section.
