Our sharpening ruler includes a small "hook" on one end so that it catches on the sharpening stone to help the ruler not slide around.
The most innovative technique in plane sharpening over the last 35 years is the "ruler trick" by David Charlesworth. Traditionally, a sharp cutting edge is achieved by honing the back of your plane blade

Love it!
Works a treat and now lives at the end of my bench on my sharpening station.

A breeze to use.
Much more stable than using a ruler. You can concentrate on the task rather than trying to keep the straight edge in place.
