Here is an alternative to a thin metal ruler for back-beveling plane irons. I use a piece of narrow brass angle stock that’s roughly 1/8 in. across and 0.014 in. thick, which creates a nice, shallow bevel. Available online and at hobby shops, the brass is easily cut to the length of your stone, and hooks nicely over the edge. I use one hand to control the projection of the plane blade and hold it against the brass angle, and the other to hold down the tip.
