What PING Says:
An all-new fully machined, three-piece design engineered with an aluminum body, aluminum hosel and 304 stainless-steel sole plate to create a highly forgiving, easy-to-align mallet.

Features & Benefits:

• Quality and precision - A solid block of forged, 303 stainless steel requires more than four hours of milling time; precisely shaping every surface and radius
  to achieve the high quality and premium look expected in a precision-milled putter.
• Control and consistency - A precision-milled face pattern, known as deep AMP (Aggressive Milling Pattern), is inspired by tour player feedback and provides
  the feel and speed control you need to deliver score-lowering consistency on the green.
• Grips Galore - Your design wouldn’t be complete without a painted-filled grip to further differentiate your putter from the rest. Blue, gold, green, orange, red, pink, yellow, purple, white and blackout are there for the choosing.
