DESCRIPTION

Details

Forged performance with the freedom to fine-tune your set.

The SMT CB-3 / MB-3 Combo Irons are designed for golfers who want the feel, control, and workability of a forged iron set with the ability to tailor performance throughout the bag.

By combining the CB-3 cavity-back irons with the MB-3 muscle-back blades, players can build a set that matches their game—adding forgiveness where it’s helpful and precision where it matters most.

Designed to balance forgiveness and precision.

The cavity-back CB-3 irons provide added stability and consistency in the longer irons, while the MB-3 blades deliver ultimate control and feedback in the scoring clubs. This blended approach supports confident shot-making without forcing golfers into a one-style-fits-all set.

Consistent forged feel from long iron to wedge.

Both models are forged from a single billet of soft 1020 carbon steel, ensuring a consistent feel, sound, and response throughout the set. Clean shaping and a brushed low-polish finish provide a timeless look that reduces glare and inspires confidence at address.

The SMT CB-3 / MB-3 Combo Irons are built for players who want total control over set composition without sacrificing forged feel or performance.

WOW!
SMT is not only back, but back with their best players iron yet! These heads are as beautiful as ANY iron I've seen and I've seen a lot since I turned pro in 1976! A customer ordered a combo set, but loved the muscles so much he ordered the 4,5,6 muscles to go blades all the way. These are truly a special iron.
