A blade clamp with first and second gripping members configured to hold a cutting blade, a lever connected to the clamp by a connection member, and a head that receives the connection member that extends through an aperture of the head. The connection member can move along a first axis through the aperture of the head and move the clamp along the first axis based on a position of the lever. The first and the second gripping members of the clamp can clamp the cutting blade along a second axis orthogonal to the first axis based on a position of the clamp along the first axis. The lever can include an eccentric cam surface that engages a cam follower. The eccentric cam surface can cause the clamp to provide a clamping force and tension to the cutting blade.

Method and apparatus for a scroll saw having a base along with an upright hollow frame with a work table attached to the lower frame used to support a workpiece to be cut. The scroll saw includes upper and lower pivotable arms driven by a motor with a saw blade between the pivotable arms. A rotatable member is included in the upright frame member for rotating an upper frame assembly in a horizontal plane. The front portion of the work table can be removed from the scroll saw to access the saw blade and the work table can be automatically leveled. Also the saw blade travels in a true vertical motion and it remains centered during operation to prevent it from creeping forward during operation.

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.

A joint made from a lightweight, thin metal connector plate with one or more through holes or cutouts, containing multiple sharp edges. The sharp edges, within the through hole or cutout, upset and engage the outer layers of a stick or sticks, or similarly essentially cylindrical and irregular members, when inserted into the connector plate and a force subsequently applied, by rotating or moving the stick or sticks off axis from the plate, to fasten the stick or sticks in place. The connector plate, being lightweight and compact is well suited to survival preparedness and outdoor activities.

This invention relates to a saw blade quick release mechanism for sawing tool and a sawing tool using same, the mechanism comprising a saw blade mount, a rotary cover rotatable on the saw blade mount, a resilient member holding the rotary cover in position, and a positioning component having a positioning member on either of the saw blade mount and the rotary cover and a positioning slot on the other one thereof whereby in case of the rotary cover positioned, the positioning member is at the positioning end of the positioning slot, and the saw blade cannot be disassembled then, while in case of the rotary cover disassembled, the positioning member is at a release end thereof, and the saw blade can be disassembled then.

A hacksaw includes a handle defining a pocket shaped to receive a hacksaw blade without a tang and a reciprocating blade that having a tang and a hole. The hacksaw further includes a support arm extending from the handle and a clamp mechanism coupled to the support arm and configured to hold the hacksaw blade or the reciprocating blade depending on which blade is coupled to the handle.
