number of lines per inch indicate the quality of the work. Too-fine checkering, however,
defeats the purpose of the work altogether.

(Fe3O4), the black oxide of iron, which occupies the same volume as metallic iron. Bluing is most commonly used by gun manufacturers, gunsmiths and gun
owners to improve the cosmetic appearance of, and provide a measure of corrosion resistance to, their firearms.
Damage that is unintended or incidental to the intended outcome.
