Abstract: A hand-operated cutting tool for cutting walling materials such as paneling and drywall. The tool has a base with a smooth, flat bottom, similar to a planing tool. Its handle is curved, attaching at at least one end of the base, and extends over the base. A cutting blade is centrally located on the base, and held in place by a blade clamp. The blade clamp is pivotably attached to the base such that the tip of the blade extends through an opening formed for that purpose in the bottom of the base, and the tip is extended and retracted by the pivoting motion of the clamp. The clamp also has attached thereto a lever arm to facilitate the pivoting. The lever arm is biased against an upstanding member which is manufactured such that the lever arm, and thus the blade tip, can assume different positions. The upstanding member has a continuous groove formed therein which winds about the member from top to bottom such that it appears as several grooves which they may correspond to several positions of the lever arm.

Abstract: A light to moderate duty work-holding clamp which also can be used as a gear or wheel puller. The body of the clamp is formed of two C-shaped plates, aligned and spaced apart by 2 blocks, one attached to each end of the C-shape. A large clamping screw is threaded through each block. The blocks are mounted to the plates in a pivotable manner, so that the two clamping screws can be pivoted through 360 degrees freely. One end of each of these two clamping screws has a bearing face for bearing the pressure to be applied by the screws. These bearing faces can be snapped on and off the ends of the screws. The other end of each of these two screws terminates in a hook-shaped portion, which can provide the gear pulling function if used in combination with a third clamping screw. This third clamping screw is threaded through a third block which is attached slidably between the C-shaped plates. This block can slide to any point along the C-shape between the first two blocks, turning as it moves along.
