The Jaws MD4 is the 2018 wedge where Callaway stopped being polite about grooves. Roger Cleveland designed a groove pattern so sharp the company named the whole line after a shark's mouth. On this Tour Grind, forged from soft carbon steel, those grooves are the point. You get a clean, compact head shape that better players tend to trust, paired with the most aggressive spin technology Callaway had put on a wedge to that date.
The Tour Grind is the shotmaker's option in the MD4 family. Heel and toe relief lets you open the face for a flop or lay it back for a bump-and-run without the leading edge sitting up off the turf. It sits best on firm to medium turf and rewards a player who likes to manipulate the face rather than swing every wedge the same way. With lofts running from 48 all the way to 64 degrees, you can build a matched set of these or slot one in as a dedicated lob wedge.
This is not a game-improvement wedge, and it does not pretend to be one. There is no oversized cavity, no heavy perimeter weighting to bail you out on thin strikes. What you get is feedback, spin, and a shape that looks right behind the ball at address. If you have the hands to use it, the Tour Grind gives you room to be creative around the greens.

About the Callaway Jaws MD4
The story here is the groove work. Callaway cut the main grooves to a sharp wall angle to grab the ball on full shots, then added a second set of micro-grooves milled between them, angled across the face. Callaway called this groove-in-groove, and the idea is simple: partial shots and open-face shots only catch a few main grooves, so the extra texture in between adds friction exactly where you need it. The higher lofts get the most aggressive spec because those are the wedges you open up and hit with a glancing blow. Forged construction gives the Tour Grind a softer, more connected feel at impact than a cast head, which matters most on the touch shots inside 60 yards where you are trying to feel the ball come off the face. The grind itself pulls material off the heel and toe so the sole rides through the turf on open-face shots instead of bouncing. Sole grind aside, the head sits compact and clean behind the ball, with a thin topline and minimal offset that suits a player who wants to see a traditional wedge shape.
Who Should Play the Callaway Jaws MD4?
- ✓Better ball-strikers who open and close the face around the greens and want a sole that works on firm to medium turf.
- ✓Players building a matched wedge set who want tour-level groove spin from the gap wedge down through the sand and lob wedges.
- ✓Anyone chasing a specialty high-loft option, since the 60, 62, and 64 degree heads give you a dedicated flop and short-side club.
Frequently Asked Questions
What is the Tour Grind and who should play it?
The Tour Grind has heel and toe relief that lets you open the face and slide the sole under the ball without the leading edge lifting. It suits players with decent hands who like to hit flops, spinners, and bump-and-runs rather than one stock wedge shot. It performs best on firm to medium turf. If you play soft, fluffy conditions or tend to hit steeply and dig, a wider sole grind will be more forgiving.
Does the Jaws MD4 spin more than the older Mack Daddy wedges?
Yes, that was the whole point of the JAWS grooves. Callaway sharpened the groove walls and added milled micro-grooves between the main grooves, so partial and open-face shots get extra friction where the ball only touches a few full grooves. In practice you get more grab on the greenside shots where spin usually falls off. Fresh grooves and a dry, clean face still matter, so keep them brushed.
What lofts should I carry in the Jaws MD4 Tour Grind?
Match your wedges to the gap below your set. A common setup is a 50 or 52 as the gap wedge, a 56 for the sand and stock full swings, and a 58 or 60 as the lob. The 48 works if your pitching wedge is stronger than 45 degrees. The 62 and 64 are specialist clubs for players who want maximum height on short-side shots and know how to deliver loft, so leave those for the higher handicaps to avoid.
Is the Jaws MD4 forged, and does it feel soft?
This Tour Grind is forged, which gives it a softer, more muted feel at impact than a cast head. You notice it most on the delicate shots inside 60 yards where you are trying to feel the ball release off the face. It will not turn a thin strike into a good one, but the feedback is honest, so you learn quickly where you caught it on the face.
Is a 64-degree wedge worth carrying?
For most golfers, no. A 64 launches high and lands soft, but it also loses distance fast and punishes a slightly fat or thin strike more than a 58 or 60. If you have a reliable short game, play firm greens, and face a lot of short-sided shots with little room to work with, it earns a spot. If you are not already comfortable hitting flops, a 60 will do almost everything you need with more margin for error.
