Unique Progressive Cavity & Muscle-Back Blade
Blends Shotmaking Control & Maneuverability
The new 525 is a non-offset, classically-shaped blade. The 3-7 irons feature a progressive cavity design with the 3-iron having the deepest cavity, the 7-iron the shallowest, and the 8-PW featuring a true muscle-back clubhead.
This progressive weighting design delivers improved forgiveness in the long irons and enhanced control in the short irons.

The face and grooves of the 525 are CNC-machined to a tolerance of .002”, providing the most consistent face surface available. Grooves have been designed to conform to 2010 USGA requirements for volume and edge sharpness.
The 525 clubhead is manufactured from a 21-8 high-nickel content alloy known in Japan as “sticky metal.” Unlike most carbon steel iron heads, our 21-8 nickel alloy doesn’t require hard chrome plating to prevent surface corrosion and as a result it is one of the softest, most solid feeling clubs in golf.
The 525 is the ideal choice if you’re seeking a sleek-looking blade that has great feel and performs consistently. It is available in a wide range of fitting options to meet your unique requirements.
