Box Cutter

Abstract

When the trapezoidal operating part with rounded corners that appears at the top in the front view is lowered, the blade can be projected from the bottom (each figure with the blade projecting, reference cross-sectional view BB). In this state, it can make shallow cuts (for example, blade protruding 2 mm) as shown on the right side of reference figure 1, which shows the state of use, or it can make deep cuts (for example, blade protruding 7 mm) as shown on the left side of the same figure. Also, if it is placed against the outer surface (ridge) of a corner of a cardboard box or used milk carton, as shown in reference figure 2, which shows the state of use, it can easily cut that part and make an incision.
