=== Finishing ===
[[File:Australian blacksmith.jpg|thumb|A blacksmith at work]]

Depending on the intended use of the piece, a blacksmith may finish it in a number of ways:

* A simple jig (a tool) that the smith might only use a few times in the shop may get the minimum of finishing—a rap on the anvil to break off scale and a brushing with a wire brush.
* Files bring a piece to final shape, removing burrs and sharp edges, and smoothing the surface.
* [[Heat treatment]] and [[case-hardening]] achieve the desired hardness.
* The wire brush—as a hand tool or power tool—can further smooth, brighten, and polish surfaces.
* Grinding stones, abrasive paper, and emery wheels can further shape, smooth, and polish the surface.

A range of treatments and finishes can inhibit oxidation and enhance or change the appearance of the piece. An experienced smith selects the finish based on the metal and on the intended use of the item. Finishes include (among others): paint, varnish, [[Bluing (steel)|bluing]], [[Bluing (steel)|browning]], oil, and wax.
