PRO 221 4-PW Iron Set with Steel Shafts

Product Overview: The Ultimate Muscleback Inspired by the iconic blades of Mizuno past – evolved to be more playable through incremental refinements in shape and weight placement. Bevelled for the appearance of a shorter face profile and narrower top line – without loss of mass in the upper blade. With dramatically more compact scoring irons than its predecessors. Grain Flow Forged in Hiroshima, Japan, with a soft copper underlay for a uniquely satisfying Mizuno sensation at impact. Features: FORGED IN HIROSHIMA JAPAN One-piece Grain Flow Forged HD from 1025E Pure Select mild carbon steel 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 the purest, softest feel made famous in the legendary TN87. Reintroduced in 2019. THICKER BEHIND IMPACT Mass relocated from the heel area to muscle pad produces a slightly muted sound preferred in our 'blind' tour tests. SHORTER & MORE COMPACT APPEARANCE Shrewdly bevelled to deliver the appearance of a thinner top edge and shorter head length – without loss of playability. CONTROLLED SHOT SHAPING Mizuno's shortest CG / shaft axis is consistent from 3-PW, allowing controlled fades and draw feels right through the set. NOTICEABLY SMALLER SHORT IRONS Following feedback from the tour, 8-PW are dramatically reduced in size – with a heavily taped upper blade to control trajectory.
