Ruler for easy cut / Ruller design

Ruler for easy cut

Easier and more accurate cutting
There is a problem that comes from the cutter knife when it is used with a ruler in a wrong way.
This ruler for cutting has a distinguishable difference from the original ones in that it has a furrow made of iron which allows the user to draw or cut a straight line.
