The cornering tool, Fig. 124, is a simple device for rounding sharp corners. A cutter at each end cuts both ways so that it can be used with the grain without changing the position of the work. The depth of the cut is fixed.

2. BORING TOOLS.
Some boring tools, like awls, force the material apart, and some, like augers, remove material.
The brad-awl, Fig. 125, is wedge-shaped, and hence care needs to be taken in using it to keep the edge across the grain so as to avoid splitting the wood, especially thin wood. The size is indicated by the length of the blade when new,—a stupid method. The awl is useful for making small holes in soft wood, and it can readily be sharpened by grinding.
