Bottom Fuller, 1" shank

Bottom Fuller tool with 1" shank

Anvil tool for blacksmithing, may need some final filing or grinding to fit the anvil. About 1" shank, cast steel tool.

About 50 x 40 x 140 mm in size about 8 mm diameter of fuller. This is quite a narrow fuller, can be ground down for a wider diameter if needed.

The fuller tool is the underside of a peen hammer or rounding hammer when wanting to agressively draw out stock.

Rather than using for instance a straight peen hammer and the flat of the anvil, having a curved fuller underneath is more efficient - drawing the steel out in fewer heats and with less hammering. A flat hammer face is afterwards used to at a high heat flatten out and remove the marks left by the hammer and fullering tool.

The fullering tool is more agressive than using a gently rounded anvil horn but works in a similar way.
