Features: FORGED IN HIROSHIMA JAPAN: One-piece Grain Flow Forged HD Boron at Mizuno's iconic facility in Hiroshima, Japan – where Mizuno irons have been produced since 1968. SOFT COPPER UNDERLAY: A microlayer of copper beneath Nickel Chrome – for an extra millisecond of control at impact. MODIFIED TEARDROP: A slightly more compact profile with an extensively bevelled top edge – creating the appearance of a thinner edge. SPIN WEIGHTED BLADE DESIGN: By flaring or tapering the upper portion of the blade, the T22 creates a higher consistent spin and a more penetrating trajectory. WET WEATHER PERFORMANCE: Mizuno's HydroFlow Micro Grooves are laser etched to release moisture and reduce spin drop off.
