Raw finish club heads are meant to rust and create a patina over time. They will arrive with a dull satin appearance but do not actually have a finish applied to them. These heads will begin to rust and build character as they are introduced to moisture and the elements.
Black finish club heads offer a clean, distinct look while also limiting glare and other distractions for the player. The Black QPQ finish has been developed and tested extensively. It provides a significant durability upgrade from the standard Tour PVD finish while providing more of a matte black look.
Satin finish club heads are elegant and timeless. The most popular finish amongst amateurs and professionals alike, the satin finish will keep your clubheads looking sharp for years to come. Without making any bold statements, the satin finish allows the craftsmanship and beauty of your clubs to speak for itself.

Taper Vs Parallel
There are two common shaft tip diameters which are .355" (Taper) and .370" (Parallel). Some shaft models are only manufactured in one diameter (Parallel or Taper) and the club head hosel has to be the same diameter to build the club properly. In order to offer more shaft options for our customers we have added .355" Taper diameter heads to several of our product lines. All of the clubheads perform exactly the same but you will find different shaft options under the "Taper" product pages. If you have any questions on this just let us know. Thank you!
