Mizuno T24 is forged in Hiroshima, Japan, using the advanced Grain Flow Forged HD Boron technology – the same place where Mizuno’s iron has been manufactured since 1968. The QUADCUT+ grooves fit tighter together than before and offer extra spin control when approaching the green. By removing weight from the toe section to shape a new hosel, it results in a smaller profile without losing the effective club face. Mizuno's patented HydroFlow Micro Grooves which are laser engraved ensure that moisture is not caught as easily on the face, which reduces spin loss in wet conditions otherwise.
