Introduction

Defying the Law of Gravity
-- show me weight configuration image (15,906 bytes)

The center of gravity (c.g.). A single point on the clubhead.

When this point is lined up with the golf ball at impact, the maximum amount of energy is released. Essential to this concept is the location of the center of gravity on the face of the club.

Every iron on the market has a fixed center of gravity. It would be unheard of to actually be able to change the center of gravity on an iron! But we have done the unthinkable. The center of gravity on Green Grass irons can be changed by rearranging the weight plates, thus shifting the center of gravity toward the toe or toward the heel of the iron.

You can change the center of gravity to match your own style of swing by redistributing the weight on the iron head without adding extra weight. It is a truly remarkable breakthru in the golf club industry.

New Concept

K.E.T.S. (Kinetic Energy Transfer System)
is a Patented (US Patent # 5,297,794) custom adjustable weighting system that provides more forgiveness and compensation on misaligned hits.

The ball when at impact with the club face and then leaving it takes less than 0.01 second. At that split moment, the ball is deformed and the energy is transferred through the clubface and to the weight plates. Then the energy transfers back to the weight plates whose weight is (mini. or) same as the ball. Finally the energy transfers to the ball and then the ball is rocketed from the club face.

The impact energy will not disburse through the shaft toward the golfer's hand. The result is a much better feeling and greatly reduces the possibility of joint sores.

Adjustments

Two weights are identical and tapered with one end thicker or heavier than the other end - both combine for a weight equal to that of a golf ball (45 grams). Weights are secured by two set screws. Adjustments cannot be made during course play - consult a professional on selecting the configuration that balances best with your style of play:

Heavy/Light weight--Click to get the drawing (14,823 bytes): weight is in center or middle of iron
Heavy/Heavy in toe---Click to get the drawing (12,684 bytes): weight helps iron to draw ball
Heavy/Heavy in heel-Click to get the drawing (11,917 bytes): weight helps fade or hit short irons straight

Specifications

Irons have a Quasi Bore ® (US Patent # 5,280,923) Thru Shaft at the hosel - the shaft is cut at an angle and secured into the very end of the iron hosel. Ex. It's just like wearing a shoe, the feet fits securely into the shoe and the angular shaft fits securely into the angular hosel.
Our club conforms with USGA rules
Iron is 17-4 stainless steel
Shafts are True Temper, Brunswick or select graphite with a frequency matched through out the set
Irons are available in 3-PW - including 1, 2 and SPW (Sand Pitching Wedge)
Extra replacement weights and screws are available
A Delta shaped weight is used to raise the center of gravity to obtain low trajectory shots. It is included with the 8 piece set.
