FULLERING
(1.) In farriery: to cut a groove into the ground side of barstock before it is turned. This may be done to provide traction for the shoe and a seat for the nail heads. Fullering allows crease nail pullers to be used to remove nails one at the time. (2.) In blacksmithing: to spread metal by forcing a wedge or semicircular edged tool into it. (3.) Wrongly used as a synonym for creasing. (4.) As used in AFA Certification and competition: A two phase process in which the stock must be worked prior to the groove being cut so that the web is the same width before and after fullering.
