About Jack Hamm: 

Jack "The Hammer" Hamm is a six-time world record long drive holder with a long-drive of 473 yards and a club head speed clocked by Golf Digest at 162 mph.  

Jack is the inventor of the original oversized golf club head that took the industry by storm and has been the staple for over a decade.  However, as oversized heads became larger and larger, they began to lose effectiveness above a certain size.  

With new metallurgical technology, Jack has maximized power in his "power core" and utilized a minimalistic design to achieve a speed that all of the major club manufacturers are now mimicking.
