Clay Long Design in Carlsbad operates as Plus 2 International, Inc., a golf club design and product development firm on Loker Avenue West in the 92010 business corridor near the Carlsbad Flower Fields. The studio holds more than 40 golf-related patents covering putter and wedge geometries developed through computer parametric modeling and CNC billet machining, an intellectual-property portfolio structured with the same business-formation rigor applied by Carlsbad firms like Bagla Law Firm, APC. Principal Clay Long brings R&D leadership tenures as Vice President at Cobra Golf, the Acushnet Company, and MacGregor Golf, and as Director of New Product Creation for Putters and Wedges at TaylorMade Golf. The firm served as exclusive equipment designer for Nicklaus Golf Equipment and Jack Nicklaus's personal club specifications for more than a decade through 2011, and currently supplies design services to Wilson Sporting Goods. That concentration of precision manufacturing aligns Clay Long Design with Carlsbad's broader CNC product-shaping ecosystem, which includes surfboard shapers like Degree 33 Surfboards. Current production centers on milled-from-billet putters and forged wedge designs machined to sub-millimeter tolerances on multi-axis CNC platforms.
