Abstract: A skate blade sharpening tool that has a cylindrical sharpening stone that is positioned directly over the blade and adjusting the slot width in the sharpener using thumb screws to match the blade width. When tightening the thumb screws, the two halves of the tool handle will decrease the slot width onto the blade. This pressure on the blade will force the through shaft and cylindrical stone to be centered over the blade. The sharpening stone will remove metal to match the shape of the stone each time the sharpener is moved back and forth along the blade. The sharpening stone has gears on each end of the stone that match the gears inside the two-piece body. As the tool is moved along the skate blade, the sharpening stone will incrementally rotate within the body when the direction is changed in the reciprocating motion by the user's back and forth movement. The sharpener also has a deburring stone mounted to the black of the handheld sharpener.

The battery pack includes a battery pack housing and battery cells provided in the battery pack housing.

Abstract: A utility blade includes a first blade retention feature positioned on a proximal edge of a tang of the utility blade. The proximal edge is angularly offset from a longitudinal axis of the utility blade. The first blade retention feature is associated with an engagement axis parallel to the longitudinal axis of the utility blade. The utility blade is configured to translate along the engagement axis to cause the first blade retention feature to engage with a first blade engagement component of a blade holder. The utility blade further includes a second blade retention feature positioned on a second edge of the tang of the utility blade. The second blade retention feature is positioned along the longitudinal axis of the utility blade and between the first blade retention feature and a distal tip of a cutting portion of the utility blade.

Abstract: 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.
