Reverse ruler / Product design

Reverse ruler

When use a regular ruler to draw a line, we need to locate the start and end position and inertial effects will make drawing process hard to be controlled. The reverse ruler, however, reverses the scale, thus only need to fix position in the beginning. Now, drawing line becomes very convenient.
