The main concept of CUTTING RULER is the combination of a ruler and a boxcutter.
People make mistakes when they cut something with a boxcutter.
Usually they cut their fingers working with a boxcutter.
They also cut papers in the wrong direction.
To solve these problems, I suggest CUTTING RULER.
CUTTING RULER is very safe because there is no danger of cutting one's finger.
And it is accurate.
The blade goes in a straight line, so users don't make any mistakes and do the job accurately.
It is also convenient.
The paper is cut without any boxcutter.
