Following the launch of Mizuno's new range of irons, we take a closer look at how they're made

Video: Mizuno Grain Flow Forging


The precision and soft, solid feel of the new Mizuno JPX-EZ Forged, MP-54 and MP-4 irons is a result of its commitment to the ancient Japanese art of forging.

During forging, a steel billet is carefully heated to a maleable state (without distorting its internal Grain Flow structure), and hammered into a final shape.

Unlike casting, where a lower graded metal is heated to liquid form (losing its grain structure) and pured into moulds. Cast metal parts usually contain small air bubbles formed when the metal is re-set.

The Grain Flow lines, high grade steel and absence of air bubbles mean that forged irons feel softer and deliver a more consistent performance than their cast alternatives. The consistency of each forged iron head allow golfers to accurately predict the distance potential of each iron within the set.

The Mizuno Grain Flow Forging technique perfected at its exclusive factory in Hiroshima Japan produces the purest forged iron heads available.
