A reciprocating saw blade assembly that includes a drive blade and one or more side blades positionally coupled to the drive blade is disclosed. The drive blade may include a tang on a first end of the drive blade configured to removably couple to a reciprocating saw tool. A cutting edge may extend at least partially between the first end and a second end. The one or more side blades each may include a first end proximate and offset from the first end of the drive blade such that the tang of the drive blade is exposed, and a cutting edge that is at least partially between the first end and the second end of each side blade. The drive blade and the one or more side blades may be positionally coupled with at least two rivets extending through the drive blade and the one or more side blades.

A handsaw contains a blade and a handle, in which a cavity is made for inserting a marking pencil into it for the purpose of operative use thereof while in operation. The said cavity is provided with a bushing of resilient material to fix the pencil inside wherein the outlet opening of the bushing is smaller than its inlet opening. The presence of such a bushing of resilient material, tightly enclosing the body of the pencil allows the pencil to fix in the handle. In addition, it prevents the falling the shortened pencil inside the said cavity in the handle of the handsaw. It allows the pencil to use until it reaches the least possible length.

A saw 10 has a handle 11 and a blade 12 projecting from the handle. The blade 12 has an edge 14 along which a plurality of saw teeth 15 project. The saw 10 further includes a flexible and retractable saw guard 20 which is connected to the saw 10 and which is retractable from a guard position in which the saw guard 20 overlies the saw teeth 14 and a retracted position in which the saw teeth 14 are exposed.

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 pole saw, including a cutting assembly and a support assembly. The cutting assembly includes a serrated cutter and a sheath rotatably connected thereto. The sheath is provided with a groove for accommodating the serrated cutter. The serrated cutter can rotate with respect to the sheath to move into or out of the groove to be sheathed or exposed. The sheath is detachably arranged on the support assembly.

A utility knife assembly includes a case having a slot in which two blades are received. A resilient plate is secured in the slot and includes two resilient fingers to push the blades out from the slot. A switch unit is connected to the case and selectively activates either one of the two blades to be pivoted out from the slot.
