Hockey sticks or other tubular shafts have historically been cut using a hack saw with the shaft resting on the lip of a garbage can resulting in slow and inaccurate cuts. A new device for cutting a shaft comprises a holder for receiving the shaft, and an arm rotatably mounted at an end of the holder. The holder includes an internal passage, sized to receive the shaft, which extends outwardly through an opening at the end of the internal passage. A set of jaws are mounted on the rotating arm, each jaw includes a saw blade extending across the opening perpendicular to the shaft. The jaws are spring biased together at a first end for engaging the shaft, whereby relative rotation of the arm and the holder results in the saw blades sawing the end of the shaft off with high precision. Each jaw may include a lever arm extending from a second end thereof configured to receive an application of a user force to overcome the spring bias force to enable the set of jaws to be separated for mounting the shaft therebetween.

Embodiments of this disclosure provide a system and method for cutting composite materials. The system includes a material supporting surface, an oscillating saw suspended from a rotatable head on an arm, a two-axis gimbal coupled to the rotatable head for adjusting a cutting angle of the oscillating saw, and a material clamp for clasping the composite material to prevent the composite material from slipping while being cut with the oscillating saw. An automated embodiment of the system further includes a controller for instructing the oscillating saw to cut the composite material by guiding the saw via coordinated movement of the rotatable head, the arm, and the gimbal. A method of cutting a woven composite material includes feeding the material on a support surface, providing an oscillating saw blade on a guiding mechanism, and cutting the material by moving the saw blade in a direction based on the guiding mechanism.

Ring cutting jigs are disclosed that include a base; and a sliding brace. The base may include a platform and a pair of arms. A saw guide slot may be positioned within the base. Channels may be included within the base such that the sliding brace may move parallel to the channels with the assistance of pins that ride in those channels. The cooperation of the base and the sliding brace may act to secure a coil between the base and the sliding brace such that the coil may be cut into jump rings.

A saw system capable of cutting through a workpiece in one stroke is provided. The saw system includes a base, a turntable mounted on the base for rotation about a vertical axis, a support structure defining a cutting axis and fixedly attached to the turntable, and an elongated blade including a cutting edge. The turntable has a substantially planar support surface for supporting a workpiece. The support structure includes a pair of parallel sliding members having proximal and distal ends. The saw system further includes a handle assembly coupled with a bearing member, which is mechanically engaged with the sliding members, and an elongated blade fixedly attached to the bearing member. The elongated blade includes a serrated cutting edge that is acutely angled relative to the support surface.

A system for trimming fins on a downhole tool is disclosed. The system includes a jig that mounts to the shaft of the tool. A linear aperture is formed in the jig and has a closed end, an open end, and is sized to axially receive a single fin of the tool. A channel is located on an underside of the jig beneath the aperture. The channel has an inner radius of curvature. The inner radius of curvature is substantially similar to an outer radius of curvature of the shaft. The channel can form a friction lock on the exterior of the shaft and be removably attached to the shaft without fasteners. The channel is arcuate and has a selected arcuate span.
