no-back / Ruler

no-back

The edge of the ruler is beveled so that there is a certain distance between
the edge of the ruler and the surface the ruler is resting on .All you need to
do is to press the edge if you want to pick a ruler up because it will tilt right
after pressure is applied. This makes picking up ruler much easier,particuarly
for people with limited mobility in their fingers and hands and for children,
who still lack the fine motor skills.
The structure designed for a ruler easily taken from a desk, as well as different graduations carved on the both sides of it, can satisfy demands of
left-handed and right-handed persons.
