The new Mizuno ES21 Graphite wedge. Wow, this is a rare thing from Mizuno. Looks can be (purposely) deceiving. Thatﾒs the premise behind the Mizuno ES21 wedge. Mizuno believes the ES21 is far more versatile and suited more to a specific type of shot on the course, you want to get out of deep gunk and nasty bunkers then this is great, its all to do with the centre of gravity. The result is the ES 21 wedge. Mizuno bills it as an industry-first, extreme-Centre of Gravity forged wedge. The ES stands for ﾓEnhanced Spinﾔ its a higher sweet spot so its going to maximise spin all across the face, not just in one area, it will give you immense bite on the hard greens when executed correctly.
The Mizuno ES21 graphite wedge builds off the MP-20 HMB iron framework. Itﾒs a hollow-body, Grain Flow Forged construction. Specifically, a boron-infused 1025 grain-flow forged face and neck is welded to a 431 stainless steel body. This frees up a good bit of weight that is repositioned high and toward the toe. More weight leads to more mass and compared to the current T20 wedge, the ES 21 does have a noticeably higher toe. Itﾒs not in the visual territory of others but you wonﾒt mistake it for a traditional design.
The tech story centers around CG (center of gravity) location, spin and shoving wedge design in a new and bold direction. Chiefly, this allows Mizuno to place the CG exactly in the geometric center of the club. Not close to center or more toward the middle of the clubface. This is bang in the middle. Ironically, this is where most golfers likely assume the sweet spot is supposed to be. Hosels are heavy and traditional wedges donﾒt exhibit much perimeter weighting. As a result, the CG location tends to sit marginally toward the heel. When the sweet spot lives towards that hosel, better players nailing the center of the face sacrifice performance as a result.
So this corrects that. A club with more weight toward the heel wants to close as it moves through impact. This is great for helping golfers mitigate a slice or enhance a draw. But a more central sweet spot results in less head deflection on off-center strikes which allows the ball to stay on the face longer, resulting in a better chance at maximising spin. It also should help golfers keep the face open when hitting chips and pitches from deep rough.
According to Mizuno, a higher vertical CG produces better spin characteristics on off-center strikes. This translates as more spin when you hit one below the center of gravity (thin) and less spin loss when you catch it a little high on the face. It doesnﾒt mean golfers can hit it all over the face and get fantastic results. Itﾒs more that poor shots shouldnﾒt be quite as bad. And thats got to be a good thing.
