Mizuno JPX 919 Forged Iron Set

PERFORMANCE BALL SPEEDS: The reverse milled JPX919 Forged iron is Mizuno's fastest ever forging in measured ball speed.
FORGED FEEDBACK: Trademark workability and elevated feedback, the Mizuno JPX919 Forged iron delivers on every level.
A SMALL ADDITION OF BORON MAKES A BIG DIFFERENCE: Boron makes the steel billet 30% stronger, allowing greater design possibilities in a forged head.
REVERSE MILLED FACE: CNC milled from the sole up, the 919 Forged boasts a larger area of minimum face thickness for consistently increased ball speeds.
REFINED CG LOCATION: Weight removed from the face allows a deeper centre of gravity for more easily flighted long & mid irons.
