A re-engineered CORTECH face, is now 0.2mm thinner across the center point Faster and faster Chromoly 4140M: Our 3rd generation of designing and manufacturing irons using Chromoly – now taken to its limits. A re-engineered CORTECH face, is now 0.2mm thinner across the center point Forged in Hiroshima, Japan: Grain Flow Forged HD at our legendary facility - for an identifiable and unsurpassed Mizuno feel Forged in Hiroshima, Japan: Grain Flow Forged HD at our legendary facility from 1025E Pure Select Mild Carbon steel - for an identifiable and unsurpassed Mizuno feel Forged in Hiroshima, Japan: Grain Flow Forged HD at our legendary facility - for an identifiable and unsurpassed Mizuno feel Seamless Cup Face: A new variable thickness sole design allows the leading edge to act as a hinge, resulting in greater face flex and ball speeds Seamless Cup Face: A new variable thickness sole design allows the leading edge to act as a hinge, resulting in greater face flex and ball speeds FASTER. FORGED. FIRST: Chromoly 4120 allows a clubface up to 0.5mm thinner for our fastest peak and average ball speeds from a full body Forged iron Modern tour flighted: Mizuno’s Stability Frame with toe bias weighting, gives the longer CG distance needed for a straighter, consistent ball flight FASTER. FORGED. FIRST: Chromoly 4120 allows a clubface up to 0.5mm thinner for our fastest peak and average ball speeds from a full body Forged iron Harmonic Impact: Predicting vibration patters dictated 3 additional sound ribs – producing a more solid sensation Harmonic Impact: Predicting vibration patters dictated 3 additional sound ribs – producing a more solid sensation CNC Back Milled: A 6.4% wider back milled slot increases stability from off center strikes – from a smaller club head Workshop refined short irons: An even narrower sole to the shorter irons tested for clean turf interaction Workshop refined short irons: An even narrower sole to the shorter irons tested for clean turf interaction Stability Frame: Extreme perimeter weighting with toe bias for stability from off center strikes Stability Frame: Extreme perimeter weighting with toe bias for stability from off center strikes Stability Frame: Additional perimeter weighting with toe bias for stability from off center strikes Harmonic Impact: Feel impact for a fraction longer thanks to the thicker cavity pad – evolved from Mizuno’s study of vibration patterns Harmonic Impact: Feel impact for a fraction longer thanks to the thicker cavity pad – evolved from Mizuno’s study of vibration patterns Sleeker Compact Profile: A shorter blade length throughout, beveled training edge and reduced offset
Chromoly 4140M: With its high strength to weight ratio and malleability, Chromoly allows a for high strength face with a bendable hosel for fitting
Harmonic Impact Technology: Fine tuned head geometry delivers ideal impact feel and feedback
Stability Frame: Open at the heel portion to enhance stability and launch, while producing a tour preferred vibration and sound.
Seamless Cup Face: Thinned areas revolving 360 degrees around the perimeter increase rebound area for maximum ball speed across the entire face
CORTECH Design: Optimized face thickness distribution to maximize COR AREA
