Update (6/8): Our friends at Sports Marketing Surveys sent along some in-hand photos of the new Jaws wedge from the Scottish Open. For the first time, we can see the wedge has full-face grooves and is stamped with “Full Toe” on the hosel, leading us to not-so-expertly suspect this might be called the “Callaway Jaws Full Toe.”

Callaway introduced the most recent iteration of its Mack Daddy line in September of 2019 with Jaws MD5 wedges. So, you don’t have to be the savviest of GolfWRX forum members to deduce we’re due for another generation of Callaway wedges soon.

I mention all of this as a preamble to ask the question: Is this design we spotted in the bag of Chase Seiffert at the Rocket Mortgage Classic the next Callaway Jaws wedge? (and might we be sold bold as to christen it the “MD6”?)

The answer according to Callaway? Not exactly.

The official word from the Carlsbad-based company, “This is a prototype wedge. We’re constantly testing prototype products with our staff pros out on tour.”

In other words, maybe it is, maybe it isn’t, but they aren’t saying.

Regardless of whether this is the “MD6”, it is a new wedge design with a different channel in the rear of the club. Given the trend toward moving mass around in wedges, we can assume this is done in order to optimize weight placement to enhance launch and offer a measure of forgiveness. There certainly looks to be more mass high in the toe of the wedge.

Enhanced grooves were a big part of the MD5 story (generating lower launch, higher spin than with the Mack Daddy 4). Indeed, Callaway marketed the Jaws grooves as “the most aggressive grooves in golf.” It stands to reason that, if this is the MD5’s successor, there will be improved groove technology here as well — but that’s difficult to determine from a spy shot of the cavity of the club and no comment from the manufacturer!

We’ll keep an eye on Callaway staffers’ bags in the tournaments ahead and will certainly let you know when we have more information.

In the meantime, speculate away! What do you think about this design? Does this have the look of a wide release to you or is this a more limited prototype? Let us know in the comments.
