A pneumatic valve assembly with a trigger for switching the pneumatic valve assembly between two or more valve operation modes is disclosed herein. The valve operational modes are determined by selection of fluid conduits by a trigger valve assembly of the pneumatic valve assembly which interconnects fluid conduits to a main valve, pilot valves and a pneumatic cylinder of a fluid powered pole saw and wherein a piston located in the pneumatic cylinder is mechanically coupled to a cutting blade of the pole saw and the trigger is operatively coupled to the trigger valve assembly, wherein the pneumatic valve assembly is axially aligned with pneumatic cylinder.

A scissors attachment can also be attached to the reciprocating tool for cutting one or more sheets of material. The scissors attachment includes an extension bar and first and second blades pivotally attached. A tool chuck coupling connects one of the blades to the reciprocating tool chuck of the reciprocating tool. A bar slot can be integrally defined on the tool or defined on the neck mount assembly for receiving and securing in place the extension bar. A method of stabilizing a cutting instrument is also provided. Additionally, a method of cutting material is provided.

A reciprocating saw adaptor is provided. The adapter includes an insert blade and a base body. The insert blade includes a first end opposite a second end. The first end is sized to fit within and releasably retain to a reciprocating saw insert region. The base body includes a first end opposite a second end. The first end of the base body is fixed to the second end of the insert blade. The base body includes an opening formed on the second end leading into a threaded internal portion forming a female threaded receiver. The threaded female receiver mates with a threaded male portion of a coping saw.

An ice cutting apparatus is structured to have at least: a two-hand gripping handle; a motor in drive communication with a circular drive gear; the circular drive gear; a reciprocating geared lever configured to be driven by the circular drive gear; and a serrated blade engaged with the reciprocating geared lever, the serrated blade configured to reciprocate as the circular drive gear rotates.

A reciprocating saw blade for use with a reciprocating saw, the saw blade including a body including a first substantially planar surface and a second substantially planar surface opposite the first surface, an attachment portion for coupling the saw blade to the reciprocating saw, a cutting edge including a plurality of cutting teeth, and a rib element including a pair of outermost rib members. One of the outermost rib members is proximate the cutting edge and the other of the outermost rib members is proximate a back edge of the blade opposite the cutting edge. Each outermost rib member includes a first portion and a second portion. The first portions of each of the ribs are substantially parallel to one another.

A tool that cuts a hole for a single or double electric gang switch box. By having four blades, all cutting at the same time and in the shape of the switch box, a more accurate and appropriately placed hole may be provided. The hole saw may be configured with two centering drills so the tool is guided into the cut. An eccentric drive mechanism converts a rotary drive into reciprocating movement of perpendicularly opposed pairs of blades to cut a rectangular opening.

An angle adjustable saw includes a handle including a first cover body and a second cover body. One of two ends of the handle includes an opening. A space is formed in the handle and communicates with the opening, the first pivot hole and the adjustment hole. A blade includes a clamping portion inserted into the space of the handle through the opening, and being pivotably relative to the handle by a control assembly. Multiple protrusions are formed on a distal end of the clamping portion. Multiple recesses are formed between the protrusions. The control assembly includes an elastic button and a limiting component respectively connected to the first and second cover bodies of the handle. The limiting component has a block and is movable by pushing the elastic button to engage the block with one of the recesses of the clamping portion to set the blade at an angle.
