C-Groove
There is no substitute
Harold Swash
Inventor of C-Groove Technology

Harold Swash, inventor of the C-Groove putter, has more than 40 years experience in the golf industry as a teacher, club designer and inventor of putting aids and golf clubs. He has assisted many top professional and amateur golfers with his innovative putting training techniques, including Paul Azinger, Darren Clarke, Ian Woosnam, Costantino Rocca, Bernhard Langer, and Nick Faldo.

Swash has experimented with, and exercised the use of, mechanical and geometric principles and has applied them to the art of putting. His putting philosophy is one aimed at achieving a pure strike while controlling tension.

Swash is responsible for many of the "firsts" in golf:

  • He was the first to introduce Face-Balanced putters

  • The first to apply Electronic Flex Meter Unit to shaft development

  • The first to create the triple and quadruple bent putter shafts to achieve face-balancing.

  • Today, Swash provides golfers with putting "Teach Ins," where he instructs golfers how to improve their putting action, and he can be seen frequently at U.S. PGA events helping professionals improve their game.
