Hi Jag! They have been working on this for 2 years. A full set of irons is around $900.00. The shafts by themselves are available at Golfworks for apx. 70.00 ech. We had an opportunity early on to buy a set of irons before they got placed in retail locations. My husband really likes his and is sold on the feel. The shockblock technology is quite an improvement according to him. His game really hasn't improved a bunch, but others, who play a lot have seen their game improve. He does feel his distance with his irons is much better with these. The patents encompass golf and certain areospace uses. here is their website... http://www.e21golf.com/ Hope you like what you see! RB has some fine posters also!
