Mizuno introduced Boron to its irons when it introduced the JPX850 Forged and we were very impressed.

The success of the JPX850 Forged, made with Boron added into the steel for a stronger and thinner face to generate faster ball speeds, has led to Mizuno introducing Boron to the MP line of irons for the first time with the launch of the MP-25 irons.

Mizuno says the MP-25 is the first true high ball-speed iron specifically designed for tour players through to low to mid handicap amateurs, and it was this goal together with player consultation that has shaped the design of the club.

Rather than cramming distance technology into a smaller clubhead, Mizuno has created the MP-25 with a pre-determined tour dictated profile, and then added speed and distance with the introduction of Boron.

The heads of the MP-25 are made with Mizuno's Grain Flow Forging process from a single piece of 1025 Boron Steel. Grain Glow Forging adds a consistency of grain in the neck and hosel for greater consistency and distance control from each iron.

The Boron has allowed Mizuno's designers to engineer a Micro-Slot pocket cavity into the 3 to 6 irons that generate faster ball speeds without impacting on the feel and touch demanded on tour.

Head profile is a crucial aspect of Mizuno's design, and the shape and profile was crucial in ensuring the MP-25 met the criteria of its target players.

Tetsu Kanayama of Mizuno's Japanese R&D team:

We started off with a tour-preferred chassis, and developed our technology to get the most ball speed from that size. The craftsmen at Yoro, Japan kept the CAD engineers on a tight leash, so the final iron was something we could confidently show our tour players!
