Callaway claims that the new wedges created by master wedge maker Roger Cleveland have the most aggressive grooves in the game
Callaway has announced the release of the new JAWS MD5 wedges, designed by master wedge maker Roger Cleveland and promising a new level of grip and spin from all types of lies.
For Cleveland and his Callaway Research and Development team, it was all about the grooves. The word that the company uses to define their approach and the new grooves is "aggressive".
The grooves in the JAWS MD5 wedges are more V-shaped and have a tighter edge radius, which allow the face to "grab" the cover of the ball -- this is what promotes greater spin for greater control around the greens and on approach shots.
But it's not just the grooves, it's also what Callaway calls "microgrooves", which protrude from the face between the grooves. Combine those with soft feel from the 8620 carbon steel construction and Callaway feels that they have maximized their ability to spin the ball.
And testing seems to back this up, showing 500 rpm more spin on a 40-yard pitch shot (with the launch angle decreased by 1 degree).
The JAWS MD5 wedges have over 20 combinations of loft and sole grind, so that players can find the look and feel suited to their preferences. They will be available in stores on September 20 at a price of $159.99 each.
Customization Options
Loft options: 46, 48, 50, 52, 54, 56, 58, 60 and 64 degrees
Finish options: Platinium Chrome, or Tour Grey
Shaft options: True Temper Tour Issue 115 (steel), or Project X Catalyst 80 (graphite)
Grind options: C, X, S, High W, and Low W (see below for descriptions courtesy of Golfweek)
C – A moderately wide sole with relief in the heel and toe areas.
X – A high-bounce version of the C-Grind for players who have a steeper angle of attack into the ball.
S – A standard, straight and versatile sole for players who rarely open the club face.
High W – A wide-soled option with extra bounce.
Low W – Popular on the PGA Tour, this grind has a narrow heel so players can open the face. Ideal for play on tight lies.
