Nail File for Many Uses

Need a small, precise file to use on a variety of materials? A nail file coated with synthetic sapphires is ideal. The ones I am currently using came from the cosmetics aisle of a local supermarket; dollar stores, Walmart, etc., will probably have similar.

These files will work on metal, ceramic, and glass, as well as softer materials; they'll work on anything that's softer than sapphire. Best of all, they're inexpensive; they're not fancy brand names, and they cost $0.99 each-- 99 cents! Imagine using them to deburr, round off edges, sharpen dull things or dull sharp things, improve the fit of parts, etc etc-- scores of uses. Enough said.
