These fuller's are a slim, stream line design. If it is a narrow fuller you want, you can have it! If you want a wider one, just lean the fuller your last pass through. You can make it any width you want.

Fuller's are made using S7 Tool Steel. They are slightly softer on the striking end, and design to mushroom there. It is up to the user of the tool to learn how to properly maintain the tool in a safe, working condition. The cutting end of the tool is hardened for maximum wear. The handle is made of mild steel.
