HANDSAW
20220097251 · 2022-03-31 ·

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.

PORTABLE SAW WITH CIRCULAR BLADE
20210187638 · 2021-06-24 ·

A single-hand operable portable hand-held saw, including a handle portion with a motor. The motor is operably connected to one or more drive gears positioned on an interior side of a protective cover. One or more idle gears are positioned on an interior side of the protective cover. The idle gears and the drive gears are operatively coupled with and rotatably engaged with an annular saw blade. A throat opening in the protective cover is positioned adjacent a stop guide for stabilizing the saw against a material during cutting operations.

Handsaw
10414063 · 2019-09-17 · ·

A handsaw is provided with which chip clogging can be reduced significantly, the pitch of the tooth points can be made fine, the cut end face, called top edge, of each tooth can be increased in area, and moreover, cutting resistance is kept small and good cutting performance is ensured. The handsaw has a plurality of saw teeth arranged on a longitudinal edge (21) of a saw blade (20). The saw teeth are configured as a combination of crosscutting teeth (X) of triangular or trapezoidal prism shape and ripping teeth (Y) of parallelogram-based prism shape. The prism-shaped teeth constituting the crosscutting teeth (X) and the ripping teeth (Y) are configured such that at least adjacent prism-shaped teeth rise at a same rising angle () from an edge surface (21a) of the longitudinal edge (21) of the saw blade (20), to cause a space (S) between the adjacent prism-shaped teeth to be constant in a rising direction in which the teeth rise.

A handsaw with which chip clogging is eliminated significantly, the pitch of the tooth points kept fine rather than coarse, a large area secured for the cut end face, degradation in cutting caused by the chip clogging prevented sufficiently. The handsaw has a plurality of saw teeth arranged on a longitudinal edge (21) of the saw blade (20). The saw teeth are formed as prism-shaped teeth (30) each having a shape of a prism, which are configured such that at least adjacent prism-shaped teeth (30) rise at a same rising angle from the edge surface (21a) of the longitudinal edge (21) of the saw blade (20), to cause the space (S) between the adjacent prism-shaped teeth to be constant in the rising direction.
