Orion HTMB-S Custom Iron Set
The second in the HTMB series.
A high-performance forged iron has arrived that combines MB's signature "sharpness" with "distance" and "stability".
The "HTMB-S IRON" is a mid-size head type made using a single-material (S20C) forging process.
It is a model that pursues stability at the point of impact while retaining the design and solid sound of the HTMB IRON. Compared to the HTMB IRON, the blade and sole are slightly thicker to provide a sense of security, and it has a straight neck that is preferred by intermediate to advanced players, resulting in a form that is easy to handle.
Both the leading edge and trailing edge have a certain degree of chamfering, so you can feel the bounce and get a smooth release and swing-through.
*HTMB is named after the initials of HIMEJI × TSUBAME MUSCLE BACK.
The second release in the HTMB series.
A high-performance forged iron that blends the sharp precision unique to muscle backs with added distance and stability.
Introducing the HTMB-S IRON—a mid-sized head forged from a single billet of S20C soft carbon steel.
While maintaining the bold impact feel and signature design of the original HTMB IRON, this model is engineered for enhanced consistency at impact.
Compared to the HTMB IRON, the blade and sole have been slightly thickened to provide a greater sense of confidence at address. The straight neck preferred by mid-to-advanced players offers exceptional workability and control.
Both the leading and trailing edges are finely chamfered, allowing for a smooth turf interaction and clean, confident strikes through impact—all while preserving a subtle bounce feel.
*The name HTMB derives from the initials of HIMEJI × TSUBAME MUSCLE BACK, representing the fusion of craftsmanship from these two iconic regions.
