Callaway Mack Daddy 5 – Bite With Jaws

The Callaway Mack Daddy 5 will put 500 more revolutions on your wedge shots for a quicker stop and more accuracy says

chief wedge club designer Roger Cleveland. Because of the innovative groove design, by Roger Cleveland, the resurgence of the Jaws name is truly justified.

A tighter edge radius was the biggest problem to solve. Top Machine shops around the world balked at what was being asked of them. What Dave Neville, Callaway’s senior director, brand management was looking for was basically a no radius on the edge of the grooves.

This was a huge step up from the Mack Daddy 4 that had a 5-degree groove wall angles on lofts from 54 to 60 degrees. The wall angles on Mack Daddy 5 is a razor-sharp 37 degrees, which allowed Callaway to generate 11 percent more spin (500 Rpm) with a lower, more controlled launch angle — especially on shots from 30-40 yards.

How Grooves Were Produced

According to Cleveland, it takes roughly 9 minutes to machine just the grooves on the new wedge — not including the groove-in-groove — with a cutter that makes it through 15 heads before it must be replaced. To make the initial batch of MD5 Jaws wedges, Callaway went through roughly 50,000 cutters to ensure each set of grooves had the necessary bite. It’s without question the tightest tolerances ever achieved by Callaway.

Just like the MD4 the lower lofted MD5 wedges (52 degrees and below) will have a less aggressive 20D groove for controlled spin on full shots. A Micro-Positive surface texture pattern was also milled into the flat parts of the face to increase the contact points between the cover and grooves.

The three raised “microridges” expand the length of the hitting area by grabbing the ball’s cover at 84 different contact points to generate more spin on a variety of shots.

Cleveland changed the shape of the 46-, 48- and 50-degree offerings, reducing the head size (heel-toe) which blends their look with an iron set. The sand and lob wedge options in the lineup will have a more traditional Mack Daddy profile.

Sole Design

The leading edge was straightened on the pitching wedge and gets progressively tighter going into the higher lofted offerings to allow the wedge to produce clean contact on tight lies for more control.

A new low-bounce W-Grind gives Mack Daddy 5 a fifth grind option. Designed after the custom grind that Cleveland was already making for players on Tour, the low-bounce W-Grind (58 and 60 degrees) has less bounce (8 degrees) with a narrower heel and tighter front-to-back radius for increased versatility around the green.

“This wedge will give you a bit more forgiveness than the C-Grind,” Cleveland said. “It’s certainly for the better player, which is why so many players are Tour are using it at the moment.”

The high-bounce W-Grind (12 degrees) comes in six lofts (50, 52, 54, 56, 58 and 60 degrees) with a wider sole at the center and toe and moderate heel relief. The wedge is ideal for open face shots; it also helps golfers from digging too much into the turf through the addition of effective bounce.

The C-Grind (54, 56, 58 and 60 degrees) has been updated with a reduced bounce angle, wider middle section of the sole and increased heel relief to boost versatility.

The S-Grind (46-60 degrees) — also known as the standard grind — has slight camber, moderate heel relief and a straight leading edge. It’s a very conventional wedge that performs well in all conditions.

Lastly, the X-Grind (58 and 60 degrees) features a narrow, high-bounce crescent sole. With the low point near the front of the sole, it’s a preferred option for players who have a moderate-to-steep attack angles on medium-to-soft course conditions.

Bottom Line

The Jaw grooves really does deliver that one hop and stop spin on the greens. You will find the spin levels will be very consistent when hitting across a variety of shots and lies. Not only will you be getting good spin on full shots but also on half pitch shots.
