Those last specs might need some explaining. “Laminated” means layers of wood—often maple--glued together. Most purists in the “wood-wood” era insisted on solid blocks of persimmon. But Hogan manufactured clubs, and he loved to experiment, and he found laminates to be perfectly fine. “Tipped” means that the bottom of the shaft was driven through the club head, for still more stiffness; Ben’s clubs were about as limber as telephone poles. “Bulge and roll” is the side-to-side and up-and-down curvature along a wood’s face, an ingenious late-19th century invention that corrected a bit for mishits. Hogan did without B&R because he didn’t mishit much, and he wanted to know when he did.
