The Mizuno Pro S-3 irons are a stunning new blade for 2025, combining the heritage of the brand in a top-class performing modern design.
Designed using Mizuno’s historic forging processes, the S-3 model is a shallow cavity-back iron yet boasts the classic look of traditional blades.
Suited to elite level golfers, the S-3s deliver precision, control and shot-shaping capabilities and feature new and improved thin topline, minimal offset and a new Triple Cut Sole design.
The most significant benefits from the Mizuno S-3 irons in the exceptional feel and feedback they offer from the compact blade produced from Grain Flow Forged 1025E mild carbon steel.
They join a range of new 2025 launches from Mizuno including the S-1 irons, T-1 and T-3 wedges and Pro S and Pro X golf balls.
In January 2026, two more Pro Series models were launched with the M-13 and M1-15 irons unveiled.
Mizuno Pro S-3 Irons Specs & Design
The 2025 Mizuno Pro Signature Series S-3 irons are designed for elite golfers who prioritize precision and feel from their irons.
Made from Grain Flow Forged 1025E Carbon Steel with a copper underlay, feel is what Mizuno have honed in on in the new launch and the delay soft responsiveness and enhanced vibration patterns and smoother ball striking.
The irons are a shallow cavity-back design with a compact blade length and straighter lines for the classic blade-like look.

The topline has been made thinner in this S-3 model and the minimal offset benefits the shot shaping the elite golfers are looking for.
Mizuno have added a Triple Cut Sole design to the new release in order to enhance turf interaction thanks to the beveled edges preventing digging in on impact.
The S-3 irons are available in 3-iron (21 degrees) to Pitching Wedge (46 degrees).
Mizuno Pro S-3 Irons Review: Are they any good?
Mizuno have combined classic heritage forging processes with the modern styling of bladed irons in a seriously good looking product.
The feel is softer than any previous blades from Mizuno with a buttery feel from this new launch, making shot-shaping and control more impressive.
The blade length has been shortened making them seriously compact, so it advisable not to consider the S-3s unless you play at a high level. The JPX 925 Hot Metal range is the better option for handicap golfers.
