Ruler-Cutter is a combination of ruler and Stanly knife. It allows for the simultaneous measuring and cutting straight lines.
It is difficult to cut straight lines on paper, corrugated cardboard, etc. We need a long ruler, a blade, and great strength from both hands. Ruler-Cutter is a measuring ruler with a central slit through which a button passes. The blade is stored safely in the button. So, it can be used as a ruler only.
It is easy to use. Simply press the button to make the blade pop out. Pull the button backwards until you reach the desired length, exerting strength as you do. The material will be cut neatly and precisely.
