Scale rule ~ ultra rigid

This rule has six different, very clear, markings, all metric, to enable easy scaling and measuring. It can also act as an excellent straight edge, although the upper edge can dig into the fingers. We provide a cure for this by shipping with a plastic binding rib. This obscures two of the scales, but you are able to select which ones, since it is easy to remove and change.

The scales start a little distance from the ends. The ends are cut square, but they are not suitable for using as end-markers.
