Description
The Stanley No. 50 Plane iron honing guide fixes into the slot of the blade and allows to quickly set the bevel to either 25 or 30 degrees and the brass roller helps you maintain the correct angle whilst sharpening on the stone. Not too easy to come by outside England. Stanley Patent no. 605333. Brass will probably clean up a bit, but we haven’t tried.
Not the best example we’ve seen, but all there.
