This three-club set—5 Iron, 6 Iron, 7 Iron—demonstrates precise shaping in 316 stainless steel on the Matsuura LUMEX. The focus is creating stable stepdowns, consistent wall thickness, and a clean blend surfaces across faces, soles, and cavities. Setups remain repeatable while edges stay crisp despite running dry. The result: consistent geometry, smooth transitions, and production-ready parts for athletics applications.
