Amplifi Pivot Stomp

Introduction of Nickel Chromoly - A new material with so much additional ball speed that engineers have focused on feel and stopping power. 4335 Nickel Chromoly is 35% stronger than the original Hot Metal material and allows for a highly energetic, 8% thinner face. Combined with Mizuno's vibration-controlling V-Chassis and deep center of gravity design, the JPX923 Hot Metal irons are as comfortable and controllable as they are long.
