Precision Flat Ruler Steel (Straight Edge) by VERITAS
A precision flat ruler is very useful for example for adjusting the machine tables of jointers and for checking the flatness of a plane sole. These solid steel rulers are of high accuracy. Both edges are precision-ground with an accuracy of 0.025 mm over the entire length. It is available in three lengths. The high weight of these steel rulers has the advantage that they remain standing on the edge while making adjustments. The steel is vacuum-hardened to ensure that the usual stresses in the steel that allow bending are minimized. Not stainless!
Note: If you are left-handed, you can quickly convert the saw guide:
1. Unscrew the dark guide handle (2 screws), turn it 180°, and screw it back on from the other side.
2. Unscrew the side stop (2 screws) and simply mount it on the opposite side.

The 12 Inch (305 mm) ruler is a very handy size for checking the flatness of plane soles and sharpening stones.
It is also advantageous wherever a long ruler simply becomes too unwieldy.
The 24 inch (610 mm) ruler is very versatile for setting up machines and checking the flatness of longer hand planes such as jointers.
