Saw wrest made out of a solid piece of steel with round cutouts evenly spaced along one side of the outer edge. The cutouts are varying sizes and widths in order to allow the user to sharpen different sizes of blades. Below the cutouts the tool narrows to have a thin handle with an angled point at the bottom.
The simplest type is a saw wrest which is nothing more than a piece of steel with slots cut into the edge. The slots are of various thickness for different thickness blades. Setting a saw means bending alternate teeth outwards to either side, making the cut wider than the blade, so that the latter does not jam.
