Sawyers anvils are a heavy flat block used to tension or “tune” big circular saw blades. The blade sets on a stand where the sawyer can rotate the blade while it is setting flat on the anvil. The Sawyer strikes the blade in a regular pattern to put tension in the metal so that the blade does not flutter or vibrate while turning.
The same system us used to tune cymbals.
