Mizuno JPX-580 4-PW, GW Forged Iron Set with Steel Shafts

After six years of development, the introduction of Boron to Mizuno's Grain Flow Forging process allows the JPX-850 Forged Iron to overcome the distance limitations of traditional forged irons.

Mizuno's new material is 30% stronger than its traditional 1025E steel billets, allowing for a thinner face and extreme ball speeds. The result is an incredible iron that combines Grain Flow Forged precision and feel with shocking distance. A combination that was unachievable before Boron.

This new, thinner face is reinforced strategically by a Power Frame cavity which places weight to the extreme corners of the club head for maximum forgiveness along with increased distance. A clean, sleek design combined with these breakthrough technologies delivers an iron that looks and plays like nothing before.

Mizuno JPX-580 Forged Iron

"It took six years from the start of our development work with Boron to get to this breakthrough point. This is distance generated by genuine technology, rather than just cranking lofts or using longer shafts. It used to be that you had to give up distance to play a forged iron, but with the JPX-850 Forged, you no longer have to."
Chris Voshall
Senior Engineer
