a rare and now anachronistic tool for making wood pegs in the form of a handplane modified with ridges in its sole and blade, in order to gouge uniformly spaced, v-shaped slots out of the surface of wood
Two passes were taken over the end grain of each block with the plane, at right angles. This created a uniform grid of four-sided points. Rows of these points could then be split away into sheets from the pointed side, and the sheets then split into pegs.
