Each Hand Forged® Ball Mark is made using Mild Steel in Portland, Oregon, USA by a second-generation blacksmith. Designed by SEAMUS GOLF and inspired by the mesh dimple golf ball popular during the 1920s, this mark carries forward the same aesthetic as those who striped it in the back in the day. Each coin is heated to approximately 2200 degrees in a white-hot fire. The red-hot metal is then shaped on an anvil like soft clay, using only the most ancient tools of the craft: hammers, chisels, punches, and the hand of the blacksmith. Each ball mark is then sanded, buffed, and tumbled individually, and the results are completely different and unique between each ball marker. Choose to add your own custom stamp at no charge for an even more personal ball mark. Dimensions: Ball Marks measure 1.5 inches in diameter. Includes Free Custom Stamping Complimentary personalization hand stamped by one of our in-house artisans is included on all of our Hand Forged® items.
