摘要： A cold knife holder capable of pushing and pulling operations, includes a main body forming a chamber and a slot, a handle, a detent member, a first spring and a first steel ball. One side of the main body forms a perforation which communicates with the chamber. The handle includes a sleeve, a connecting rod and a grip rod. Both ends of the connecting rod are respectively connected to the sleeve and the grip rod, and the sleeve is pivotally sleeved on the main body, so that the handle is rotated relative to the main body, and the first or second caulking is connected to the perforation, and the detent member is arranged in the chamber. The first steel ball is pivotally embedded in the perforation, so that the detent member drives the first steel ball to be embedded in the first or second caulking, thereby positioning the handle.

摘要： A box reducer for trimming or reducing the size of a cardboard box is disclosed. The current invention allows an operator to reduce the size of an existing cardboard box after unnecessary material is removed by a knife or a cutter. The current invention improves prior arts in two ways. First, the invention contains a stabilizer which allows itself to travel in a stable way along the top edge of the flaps of the cardboard box while marking a line to be folded to create the cover of the box. Second, instead of using perforation as prior arts do, this invention uses compression to create the line on the flaps of the cardboard box. Then the operator can fold along the line to create the covering flaps, thus, a reduced box.

摘要： A fruit and vegetable peeler and carving tool has a handle with a first side and second side extension extending from the front of the handle. Each side extension has a forward lever which is positionably affixed at a forward vertical plurality of lever affixment position, and a rear lever which is positionably affixed at a rear horizontal plurality of lever affixment position. The forward lever and the rear lever of each side are connected together in parallel with a depth adjustment rod is connected between them. A triangular handle-facing fruit and vegetable peeling and carving blade has a convex upper surface and a concave lower surface. By drawing the fruit and vegetable peeler and carving tool into a fruit or vegetable, the triangular handle-facing fruit and vegetable peeling and carving blade cuts into the fruit or vegetable to a depth controlled by the position of the depth adjustment rod.

摘要： A package opener includes a body having a first half and a second half. One or more blade cartridges are sandwiched between the first half and the second half, the blade cartridges including one or more blades, and for each of the one or more blades, a blade shroud which protects against accidental injury from the blade. The blade shrouds are constructed of a resilient material allowing the blade tip to cut into a material while the sides of the blade remain covered. The blade shroud can include substantially identical guard portions disposed along opposing lateral sides of the blades.

摘要： A self-propelled cutter has a gear assembly to provide both downward and forward force on a material to be cut. A gear assembly includes a drive input gear that engages with a transfer gear and propulsion gear engaged with the transfer gear by a lever arm. The drive gear and transfer gear are coupled and fixed to the cutter body but the propulsion gear rotates about the transfer gear via the lever arm. This gear assembly enables the propulsion gear to move as required to provide both downward and forward force on a material to be cut, such as a cast. A self-propelled cutter may have a drive input that is coupled with a drive input device, such as a crank or an electric motor. A cutter may have a first gear assembly on a first side of the cutter body and a second gear assembly on a second side.

摘要： Line cutters that may be incorporated into other items, such as garments or paddles. A garment that incorporates a line-cutting trim component allows a wearer to easily cut line or cord while fishing or engaging in other activities. The trim component includes a housing with an opening, and a line cutter partially extending into the opening. The trim component can be secured to the garment using a rivet, or sewn onto the garment. In another example, a paddle may incorporate a line cutter as part of a spring clip used to secure together the tubes of a multi-piece paddle.
