13th-15th century. Fine quality for light work, perhaps saddle making. Furniture was nearly all oak pegged at the time and a claw hammer would not be used. Iron, 4” height, forged with banded base conical socket. Slightly curved hexagonal section neck and broadly flared claw. The junctions of the socket with the neck and claw, each with a high raised molding, a decorative feature requiring significant additional effort and skill by the smith who made it.
