The Skew Chisel, shown in Fig. 10, is used in finishing straight outlined work, such as the cylinder and cone, and for making convex curves and beads. It is bevelled from both sides to the cutting edge, which, instead of being at a right angle to the side of the tool, as in the carpenter's chisel, is "skewed" slightly. This gives better command of the cutting edge, because of a better position of the handle. The edge ought to be straight and the bevel flat, as by these is regulated the depth of the cut. The size is determined by the width of the blade. The larger sizes ought to have proportionally long handles.

The smaller sizes of chisels having straight edges are sometimes ground in such manner that the edges are at right angles with the sides, to avoid the necessity for reversing them when in use. The Round-nose Chisel, shown in Fig. 11, is usually made by grinding the edge of a carpenter's chisel to the elliptical form of the gouge. This tool is used in cutting recesses where the use of the gouge would be dangerous. Skilful turners frequently use the gouge for nearly all the work for which this tool is commonly used.
