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.
C-Groove
Technology Innovates Golf Industry With News Patented Putter
Design
In 1995, Harold Swash, known world-wide as Europe’s premier
putting coach, developed an innovative theory that would eventually
result in the United States Golf Association (USGA) and the
Royal & Ancient Golf Club (R&A) stating that the C-Groove
putter conforms to the rules of golf. |

with golf professionals on both the European & U.S. Tours,
Swash learned that when they make a perfect stroke the best
putters started the golf ball rolling almost as soon as they
struck it, while at other times, they actually started the
ball by skidding it for as much as 24 inches before actual
roll began. And while to the naked eye this discrepancy was
nearly indiscernible, Swash understood that this knowledge
was critical to discovering the secret to good putting. |

About
Yes! Golf
C-Groove technology is the invention of world-renowned putting
guru, Harold Swash, who has coached some of the top professional
players in the world, including members of the European
Ryder Cup team.
All
C-Groove putters have grooves etched at 20-degree angles
into the putter face to promote more dwell time. The grooves
create an immediate pure forward roll, thus increasing the
chance of the ball staying on line to the hole. C-Groove
putters produce up to a 600% purer roll than leading brands.
All
C-Groove putters conform with USGA and Royal and Ancient
Golf Club specifications. YES! Golf, the company that manufactures
C-Groove putters, is located in Denver, Colorado.

| Armed
with his belief that "the key to more accurate putting
is to achieve rolling motion immediately upon striking the
ball,” Swash began a quest to develop a putter that would
allow more players to putt like the best professionals when
they make a perfect stroke. An inventor with engineering expertise,
he used his technological experience to analyze what materials
and designs would work best, and he factored in expert advice
from his many students including Paul Azinger, Darren Clarke,
Lee Westwood, Bernhard Langer, Nick Faldo, Ian Woosnam and
Sandy Lyle. |

| Eventually,
Swash concluded that concentric grooves machined into the
metal face of a putter at 20-degree angles would create more
“dwell time” for a golf ball. That is, when the
crown of the grooves struck a golf ball, that ball would be
held onto the face a millisecond longer than ever possible
with a smooth-faced putter. And that additional “dwell
time” and bite would result in immediate and pure forward
roll of the ball. With immediate and pure forward roll, a
ball has a much better chance of staying on line to the hole.
Swash
took his concentric-groove concept to a golf equipment manufacturer
in Houston, Texas, in 1996. The company further developed,
then patented the design, calling it the “C-Groove.”
Initial C-Groove models produced included the CG 100 blade,
PG 100 mallet and four face-balanced blade models. All C-Groove
putters were designed to conform with USGA and Royal and
Ancient Golf Club specifications. With the exception of
the CG 100 Traditional Blade, all were face-balanced to
help promote a more consistent putting stroke.
After
the C-Groove putters were introduced, independent testing
of the putters was performed with a computer-controlled
robot that could analyze ball roll from impact through high-speed
photography at up to 10,000 frames per second.
"These
tests proved conclusively that a golf ball immediately begins
a forward roll when struck by a C-Groove putter." Everything
that Harold Swash had stated was proven correct.
The
C-Groove putter was then tested against several best-selling
brands at 20 feet. The results of these comparisons showed
the C-Groove produced a purer roll 600% faster than the
Ping Anser, 500% faster than the Titleist Bullseye, 450%
faster than the Wilson 8802, and 60% faster than the Odyssey
R-2, making it the most consistent putter on the market.
In
1997, Francis M. Ricci, a former financial consultant to
the company, became President and Chief Executive Officer.
A long-term plan for the marketing of C-Groove putters was
developed. As part of that plan, the production of all other
golf equipment was discontinued and all of the company’s
resources were concentrated behind the C-Groove product
line. The company relocated to Denver, Colorado in May 1999.
In
continuing to create putters that increase the performance
of the golf ball on the putting green and ultimately lower
the player's score, two new models have been introduced
for 2000. Both the new Center Shaft model and the Insert
model feature the patented C-Groove face invented by Harold
Swash.
In
2001, the C-Groove putter is being discovered by golfers
all over the world. Many amateurs are experiencing fewer
putts with C-Groove technology. The putters are currently
being played by professional golfers including on the LPGA,
European, Canadian and LPGA Futures Tour.
