We have to repeat moving a ruler and adjusting it to the original path again, when drawing a pen or knife with a rule because it has a limited length. But the Consistent-motion Ruler is clever and innovative that can lengthen correctly and infinitely only with a simple way, even though it has a size common to other school supplies in a pencil case. It is designed to move the part of the ruler where a thumb touches along the side of it, by separating the parts meeting a thumb and a middle finger that are mainly used for pressing and fixing the ruler. Therefore, you can move the ruler easily, moving the other side of it, after pressing and fixing one side with fingers.
