This sprue includes 24 hammers. There are three handle lengths (15", 18" and 21"); each handle length has two each of four head styles. The four head styles are Ball Peen, Double Head, Straight Pane and Cross Pane forms, which are typical forms found in most smithies. The hammers are freestyle forms based on drawings from a Victorian-era English catalogue, but are similar to those produced all around the world from at least the medieval period through the 1950's.
