FORGED IN HIROSHIMA JAPAN: One-piece Grain Flow Forged HD Boron in Hiroshima, Japan - where Mizuno irons have been produced since 1968. MODIFIED TEARDROP: Flows through the set such that from stronger lofts with straighter lines to higher lofts with softer lines. TAPERED BLADE DESIGN: By tapering the upper portion of the blade, the T24 creates incremental vertical MOI for more consistent spin and more solid impact feel, particularly high impact. WET WEATHER PERFORMANCE: Mizuno's HydroFlow Micro Grooves are laser etched to release moisture and reduce spin drop off. NEW QUAD CUT + GROOVES: Optimizing 6 groove geometry parameters delivers maximized spin for both full shots and partial shots in dry and wet conditions. 15 grooves on 46-54 degree wedges (full shots) and 17 grooves on 56-60 degree wedges (helps with partial shots). AVAILABLE IN 3 FINISHES: SATIN CHROME, DENIM COPPER OR RAW Chrome finish features soft copper underlay.
