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.

A knife attachment device, for slicing a fruit or vegetable into a long strip, includes a body, first and second arms, and first and second bottom plates. The first arm and the first bottom plate are attached to each other on one end and separated and open toward the other end at or around the body such that the first arm and the first bottom plate are elastically open to receive a knife blade therein. When the knife blade is inserted, the cutting edge of the knife blade should face the attached end of the first arm and the first bottom plate. The first and second bottom plates slide on a flat surface such that the cutting edge of the knife blade slices produce and the sliced produce comes out of a space between the knife blade and the flat surface in a long strip.
