Abstract
This product is a punching tool with a metal plate blade and a stick, designed to create handle holes (shaped like the letter C rotated 90 degrees to the left) in cardboard boxes and other boxes that do not originally have them. When using this tool, turn the stopper screw on the stick upwards, grip the stick, determine the position of the desired hole on the upper side of the cardboard box, place the tip of the safety cover against it, and slowly push the main body inwards towards the inside of the cardboard box. Push until the sharp blade of the V-shaped cutter hits the stopper screw against the end panel of the safety cover. This will create a smooth and clean cut. When you pull the stick back, the extended spring will compress, returning the safety cover to its original position and covering the blade of the V-shaped cutter again, thus safely creating handle holes in cardboard boxes.
