Option 3 : Barrette file 

Explanation:

Files are hardened steel tools for cutting, removing or smoothing metal. The shape of a file is specified by its cross-section.

Barrette files are tapered in width and thickness, which allows them to access small spaces. Only the flat side is cut, and the other sides are all safe for doing flat work. They are used for special use on dovetail guides, finishing work of internal gear teeth.

Mill saw files: Mill saw files are usually flat and have square or rounded edges. These are used for sharpening teeth of wood-working saws and are available in a single cut.

Crossing file: This file is used in the place of a half-round file. Each side of the file has different curves. It is also known as the "fish back" file.

Riffler files are used for die-sinking, engraving, and in silversmith’s work. They are made in different shapes and sizes and are made with standard cuts of teeth.
