Here is an amazing documentary from the 1970's, called "Ben Hogan-Pursuit of Excellence." It shows in great detail behind the scenes of how the Ben Hogan Company revolutionized the golf club, shaft, grip, and golf ball industry. Their Quality Control program was second to none. It was the meld of Mr. Hogan's vision and efforts to make the best golf equipment available at the time. Perfection! | Ben Hogan
