The Definition of Checkering
A regular pattern of fine grooves cut into
the surface of a stock to aid in gripping a gun. Originally done for utility only,
checkering has become an art form in itself; craftsmen adorning the borders with ribbons,
fleur-de-lys, floral carving, etc. The amount of coverage, the precise regularity, and the
number of lines per inch indicate the quality of the work. Too-fine checkering, however,
defeats the purpose of the work altogether.
