-3 PREFERRED EMBODIMENT OF THE INVENTION

A powered apparatus having a reciprocating motion is typically used with a saw blade and referred to as a reciprocating saw. The saw blade is formed with a fitting portion that is adapted to releasably engage the apparatus. Reciprocating saws are used to cut a range of materials, including wood, metal, plastic.

This technology incorporates a feature improving the versatility of a reciprocating tool and opens up new industries for the tool to be used and a greater variety of tradesmen. Reciprocating saws are used by carpenters, builders, and other users to cut wood, metal, plastic, and other types of materials and structures. The technology allows for rapid filing of metal and wood. In use, a user couples a reciprocating saw blade file to the receiver of the reciprocating saw. The user may operate the reciprocating saw to cause the saw blade to be reciprocated or moved in a back and forth motion and file a range of materials to shape.

By forming a suitable fitting portion at the proximal end of a file tool or rasp tool, can be releasably engaged to the apparatus providing reciprocating motion of the tool.

A novel means is provided for securing a file tool to the attachment mechanism of a reciprocating saw apparatus. This innovation enables rapid filing of metal, wood and other materials. In use, a user couples a reciprocating file tool to apparatus to enable reciprocating motion of the tool.

The tool may be formed with different profiles to suit different uses. For example, files can be flat, round, half-round, triangular or rectangular. The 'tooth' configuration can provide any one of a coarse cut, a bastard cut, a single cut, a double cut, etc. A rasp tool can be provided with an arrangement of round cupped teeth. It is to be appreciated that this disclosure may relate to all known file and rasp types. In general, a file or rasp tool comprises a body of hardened steel having a proximal end having a standard universal reciprocating saw attachment to releasably engage an attachment mechanism of the apparatus. The attachment mechanism is configured to restrict ejection of the tool.

-4Referring to FIG. 1 and FIG. 2A through FIG. 2D, an embodiment attachment tool 100 can have a substantially rectangular cross-sectional profile 101 (as best shown in FIG. 2D).

By way of example, the attachment tools 100 includes an elongate body 110 having a first side 111 and a second side 112 that extends in the direction of a transverse axis 113. The body is narrow along the transverse axis, with the first side 111 opposite the second side 112 (as best shown in FIG. 2B). In this embodiment, the first side and second side are substantially planar and parallel, joining at a top edge 114 and a bottom edge 115. By way of example, the top edge and bottom edge are convergent such that the body tapers towards the distal end 116.

In an embodiment the first side and second side are adapted to form an abrasive surface to form a file or rasp.

The body has a proximal end 120 adapted to form a fitting portion 121 that attaches to the powered apparatus for allowing reciprocating motion of the tool.

The fitting portion 120 is substantially planar, having a rectilinear section 121 and a protruding section 122 that extends parallel to the longitudinal axis of the tool. It will be appreciated that the fitting portion is sized to releasably engage the powered apparatus.

In an embodiment, the file or rasp portion transitions to the fitting portion via a splay transition 123. By way of example, the splay transition may have an angle between 22.5 degrees and 45 degrees. The fitting portion has a thickness of about 1.2mm-1.8mm, preferably about 1.6mm. A locking hole 124 has a diameter of about 3.5mm, and is located about 15mm from the termination (or proximal end) of the splay transition 123. A top sized (or locating) edge 125 and bottom sized (or locating) edge 126 extends for about 4mm in the transverse direction. The length of the file portion can vary between different tools, but is typically about 150mm in length.

In this embodiment attachment tool 100, the fitting protrusion portion 122 has parallel horizontal edges (127,128), which are parallel to a longitudinal axis of the tool, and extend different lengths. The protrusion portion edge 127 terminates in substantially vertical (or

-5 perpendicular) rectilinear section edge 129, which is perpendicular to the longitudinal axis of the tool.

Referring to FIG. 3 and FIG. 4A through FIG. 4D, an embodiment attachment tool 200 has a cross-sectional profile 201 having a flat first side 211 and a rounded or curved second side 212 (as best shown in FIG. 4D).

By way of example, the attachment tools 200 includes an elongate body 210 having a first side 211 and a second side 212, which extends in the direction of a transverse axis 213. The body is half rounded along the transverse axis, with the first side 211 opposite the second side 212 that is curved or arcuate (as best shown in FIG. 2B). In this embodiment, the first side and second side join at a top edge (or ridge) 214 and a bottom edge (or ridge) 215. By way of example, the top edge and bottom edge are convergent such that the body tapers towards the distal end 216.
