Since it was first released in late 2017, the Mizuno S18 Wedge has not only received the highest rating of Gold in the 2018 Golf Digest Hot list, but has also become one of the most popular wedges of 2018. If you’re an avid golfer, the Mizuno brand is one you’re surely familiar with.


For years, golfers across the globe have associated the name with a “player’s club.” While the brand has made concerted technological and design efforts in recent years to accommodate the higher handicapper , their appeal still largely lies with low handicap players. For this type of player, getting to the next level often comes down to a shot or two per round and those shots are most often inside of 125 yards. As a result, having fine-tuned well-designed wedges is of the utmost importance. The new Mizuno S18 wedges, which replace the previous S5 model are certainly no exception. With cutting edge design features, a forged (instead of cast) head, and a variety of lofts, the low- to mid-handicap player will certainly have plenty of options to customize the perfect wedge for their game with the S18.

Key Features

Unlike most wedges made by other manufacturers, the Mizuno S18 wedge is forged instead of cast which enhances feel and precision around the green.

The S18 wedge features grooves which are wider and deeper than other grooves on the market allowing for cleaner contact and increased spin on full and short shots for greater control.

Variable center of gravity heights strategically placed right behind the point of contact on the face allow for more consistent trajectory and distance control.

Design and Technology

The Mizuno S18 wedge is designed for the low- to mid-handicap player in in mind who is looking for exacting precision and control inside of 125 yards. This new 2018 model features a forged head, wider and deeper grooves, variable centers of gravity and an improved grind design that allow a player to optimize the wedge arrangement that is truly best for them.

The use of Grain Flowed Forged 1025 Boron Steel in the forging process allows for increased feel and control off of the face. This forged steel has enabled Mizuno to increase the width and depth of Quad Cut grooves for maximization of spin and control without sacrificing the lifespan of grooves commonly found in other forged clubs.

The incorporation of variable centers of gravity depending on loft has set the S18 wedge apart from other wedges on the market. By placing the center of gravity lower on the face on lower lofted wedges with a straighter face, and higher on more lofted wedges with a flatter face, Mizuno has optimized the impact point in wedges of all lofts for more consistent ball flight and distance control on both full shots from the fairway and around the green.


Compared to the previous S5 wedge, the S18 features increased toe and heel grind which allows a player to either open or close the face depending on the shot without losing the full effect of the bounce on the bottom of the club. The result is more consistent contact, trajectory, and distance control.

PROS

  • Variable loft and bounce options allow for customization of perfect wedge makeup
  • Forged clubhead provides players optimal feel and control
  • Wide and deep grooves and variable center of gravity allow for consistent contact and distance

CONS

  • Design features are for advanced players and may not be suitable for higher handicaps
  • Price is comparatively higher than other wedges on the market

Our Experience

The Mizuno S18 wedge immediately impressed us with its aesthetic appeal. It features a larger, rounder profile compared to typical teardrop-shaped wedges, which might make it appear bigger to some golfers. The wedge is available in two finishes: white satin and gun metal, both of which provide a sleek, professional look.


In terms of feel, the S18 wedge lives up to Mizuno’s reputation for exceptional forged clubs. When struck well, the wedge delivers a soft, crisp, and responsive feel that is characteristic of Mizuno’s forged offerings. Even on off-center hits, the feel remains consistent, though discerning players will notice a slight difference.


The performance of the Mizuno S18 wedge is where it truly shines. The club features a thoughtfully designed progression in its grooves, with wider and deeper grooves in higher lofts to better handle dirt and moisture, ensuring consistent spin and contact. This design is particularly beneficial for skilled players who require precise control over their shots.


Each loft in the S18 series has been optimized with specific tweaks to the sole, center of gravity (CG), and head shape, ensuring that each club performs best for its intended use. For instance, the higher lofted wedges have a higher CG to maintain spin consistency on shots hit higher on the face, a common occurrence with more extreme lofts.
