Who the S-4 suits
The most forgiving of the Signature Series: forged from a single billet, with a design that helps you launch it and keep it stable.
Curved muscle
A redesigned muscle concentrates mass lower in the head.
Higher, steadier launch
Progressive offset, a wider sole and a deeper centre of gravity work together for launch and stability.
One-piece forged
Forged from 1025E mild carbon steel using Grain Flow Forged HD for feel and feedback.
Best for
Accomplished golfers who want forged feel with extra confidence through the set.

Questions
S-4 or JPX 925 Forged?
Both are forged and forgiving. The S-4 is a one-piece muscle cavity with a players’ look; the 925 Forged has a thinner, faster face for more distance. Tell me your priorities in the form and I’ll advise.
Do I need a fitting first?
No. Most golfers can order a well-matched club from their measurements and what they play now. If you’d like a full fitting, you can book one with me in East Kilbride.
Are these genuine Mizuno clubs?
Yes. I order directly from Mizuno through my dealer account, and your club is built to your spec by Mizuno.
How long does it take?
Build times vary through the year, so I confirm the current timescale on your quote before you commit.
