The Secret Factory That Forged Irons for Titleist, Callaway and Nike — And Never Signed One

Tiger Woods' Titleist 681T irons sold at auction for $5.1 million. But the heads were tooled up at a forge most golfers have never heard of: Endo Manufacturing in Tsubame, Japan. For over 50 years, Endo has reportedly forged irons for Titleist, Callaway, Nike, Ben Hogan, Bridgestone, Mizuno and Srixon, without its name on a single club. We follow the story from a sewing machine parts shop in 1947 to the 6-gram forging standard, the EPON golf brand, Hideki Matsuyama's Masters win, and the day Srixon finally said the name out loud. Who really makes your forged irons? And why did the best forge in golf choose to stay invisible?
