Over two years in development, the 2006 version of the Kinetic improves on the original, both in form and function. Advances in Investment Casting technology allow for an incredibly easy weight adjustment system that eliminates the need for lead tape or hosel weighting. There are 4 weighting options in the form of metal screws. The screws are available in; 2 gram (aluminum), 4 and 6 gram (stainless) and 8 gram (tungsten) options. The heads can be ordered with no weight screws (MA0032), allowing the club maker to customize the head with any of the weight screw options (this allows nearly unlimited head weight, mass distribution, finished club length and shaft selection options.). The KE4 irons can also be ordered with two 4 gram weights installed (MA0022), which bring the heads to the GolfWorks standard specification weight.
The KE4 irons are also one of the most cosmetically appealing irons The GolfWorks has ever developed. The finish is a mirror polish on the perimeter and sole, with a non-glare satin finish on the toe area of the face. The top-line and face have a matching bead blast finish, another non-glare feature.
Golfworks was so excited about the results of their testing, they couldn't wait until 2006 to release the KE4 irons.
