Mizuno's S18 wedges replace the S5 and are Mizuno's first wedge named for the year in which they were released.
S18 wedges are forged from Grain Flowed Forged 1025 Boron Steel. This allows Mizuno to strengthen the grooves while maintaining a forged feel.
The S18 also features Quad Cut grooves. Quad cut grooves are wider and deeper to help funnel away dirt and water so the face makes better contact with the ball.
Mizuno also moves the CG as the loft changes to keep it positioned exactly behind the impact point on the face.
S18 wedges come in Chrome or Black IP finish.
