From the manufacturer
A winged mallet design with a “hatched out” center section. Patented.
Twenty years ago Guerin Rife designed putters with closely spaced grooves running across the face allowing a putter to roll the ball smoothly at impact. Despite initial resistance, many major golf manufacturers using alternate versions of Guerin’s original groove technology now use this idea.
While closely spaced grooves create a superior roll they also soften the impact. Simply stated, less contact surface means less hit. In tests, a ball hit in the center of a non-grooved putter travelled 25 feet. That same putter with grooves with just a quarter of the contact surface only reached 23.5 feet.
Sweet Face Technology
Hitting a straight putt isn’t easy. On a 15 footer, a ball hit just half an inch off-center will travel about 6” off line and 5% shorter. That slight miss-hit is a missed putt!
Introducing Evnroll®. Precise patent pending face milling imparts progressively more energy transfer on off-center hits to roll the ball a consistent distance with every stroke.
This unique milling pattern also gears the ball back to the center. So you can roll your putts the same distance to the same spot. Sweet.
Eliminate Miss Hits
The result is that the ball rolls virtually the same distance from center and off-center hits, meaning that Evnroll putters deliver unprecedented accuracy. That’s why it’s called “Sweet Face Technology.”
