The edge is then carefully draw-filed, i.e., the file, a smooth one, is held (one hand at each end) directly at right angles to the edge of the scraper, Fig.
153, and moved sidewise from end to end of the scraper, until the edge is quite square with the sides.

Then the scraper is laid flat on the oilstone and rubbed, first on one side and then on the other till the sides are bright and smooth along the edge, Fig.154.Then it is set on edge on the stone and rubbed till there are two sharp square corners all along the edge, Fig.155.Then it is put in the vise again and by means of a burnisher, or scraper steel, both of these corners are carefully turned or bent over so as to form a fine burr.

This is done by tipping the scraper steel at a slight angle with the edge and rubbing it firmly along the sharp corner, Fig.

156.
[Illustration: Fig.152.Using a Cabinet-Scraper.] To resharpen the scraper it is not necessary to file it afresh every time, but only to flatten out the edges and turn them again with slightly more bevel.

Instead of using the oilstone an easier, tho less perfect, way to flatten out the burr on the edges is to lay the scraper flat on the bench near the edge.
