I offer two versions of fullering tools - one for use with an anvil hardy hole and one for use with a vise. Included with either are two die sets - fuller & butcher. The hardy hole version can be made with hardy shank sizes from 3/4" to 1&1/4" (~19mm to 32mm). Please specify hardy shank size, in either fractional inches or millimeters. The vise version can be used with any vise, preferable leg/post style. The dies are made from 1050 medium carbon steel and are properly heat treated. The throat opening for each is approximately 1&3/4". My fullering tools are relatively small but can be invaluable for blacksmithing.
