Safe to Cut / ruler

Safe to Cut
Safe to Cut

When cutting paper with a box cutter and ruler, users may hurt their fingers with the blade. Sometimes the material being cut slips and cause the sharp blade to cut user’s fingers.
“Safe to Cut” is a ruler designed to protect the fingers of users, especially children. The V-shaped form of “Safe to Cut” not only allows the user to press the ruler steadily, but also protects the user’s fingers behind the “slope” structure.
