Steele Wire Brush
As you forge your workpieces, you'll invariably have oxides form forge scale. To save yourself hammering forge scale into the workpiece and then ending up with an unsightly finish, we use brushes to clean it off while hot.
The all-time greatest brush for this job is the Butcher Block Brush or farriers brush. It has wide flat spring steel bristles that are very aggressive against the forge scale and will help it rip off the material.
These brushes are 9"x4".
