More Info on Callaway X Series JAWS Wedges

From Golf Magazine (ClubTest, April 2010)
We tested: 52° loft/12° bounce, 56°/16°, 58°/13°, 60°/13° with True Temper Dynamic Gold steel shaft

Company line: "We design ‘Mack Daddy' grooves at the maximum conforming depth and width for shot-stopping spin and control so you can take aim from any lie. The ‘C-Grind' sole has relief in the heel, (Callaway X Series JAWS Chrome Wedge)toe and trailing edge. The sole contour allows you to lay open the face while keeping the leading edge low."

Our Testers say:
PROS: Among the leading wedges tested; good shots slam on the brakes; very

performer; dependable control from any lie; (Callaway X Series Jaws Vintage Wedge)offers real playability; shines around the green, balls spin and stop on halfwedge shots; repeatable flight; most applaud the blend of traditional and high-tech look.

CONS: A minority could use more distance forgiveness; a few panelists prefer a more straightforward visual package.

From Sports Illustrated Golf+ Equipment Issue (February 8, 2010)
• Designed by Roger Cleveland, Callaway's chief designer.
• Mack Daddy grooves generate maximum spin and control around the green.
• C-Grind sole improves turf interaction and provides versatility for shotmaking.
• Forged carbon-steel construction produces soft feel with amazing feedback.

The new JAWS wedges, like their predecessor X Forged wedges, come standard with a C grind along the sole. This means that some of the bounce (the flange that dips below the level of the leading edge) in the heel and toe areas has been removed to create a C-shape along the bottom of the club. This process makes it easier to open the face and use the clubs effectively from tight lies.

From Golf Magazine (January 2010)
Famed wedge designer Roger Cleveland used the firm's X Prototype irons to inspire the shape and styling for X Series Jaws wedges. The heads are forged from soft 1020 carbon steel and feature big, aggressive "Mack Daddy" (MD) grooves for added spin. Its "C-Grind" sole contour allows you to lay it open while keeping the leading edge low. Available in chrome (pictured) or dark vintage finish.

From The Shop Blog (September 2009)
Like previous X Forged wedges, the JAWS models will feature Phil Mickelson-inspired Mac Daddy grooves, which Cleveland says are as large and sharp as USGA rules allow.

"The capacity of the grooves, the width, is the max," Cleveland said. That helps to wick away moisture and debris, which should help the groove edges bite into the ball more effectively for increased spin.

Callaway X Forged JAWS GroovesProfessional golfers and elite amateurs who attempt to qualify for events like the U.S. Open will not be allowed to use wedges with Mac Daddy or other high-spin groove patterns starting on Jan. 1, 2010. Weekend players, however, can use wedges like the Callaway X Series JAWS until 2024, even during rounds played for handicap purposes.
