Fullers are required for many aspects of blacksmithing and toolmaking and have many different uses. They are often used to isolate or spread material in different directions and they are a necessary tool in the making of a rounding hammer. The 1.5” fuller has a 1.5” radius and is roughly 5/8” wide. The 3” fuller has a 3” radius and is roughly 1.5” wide. Both of these fullers are used in many operations for toolmaking as well as general forging. Both sizes of bottom fuller have a 1” hardy shank.
