AY Honors/Woodworking Tools/Chisel
From Pathfinder Wiki
A chisel is best used with a mallet. Chisels can be used for removing great quantities of wood. They can cut across the grain or slice along its length. Chisels are sharpened much the same way as knives, but the angle is a bit steeper, ranging from 20° to 35°. Often they are sharpened at two angles, such as 25° for most of the length of the blade, and 35° near the edge. This allows the blade to be resharpened by only honing a small portion near the cutting edge.
