I've searched through countless posts on the TSG blog and this is what I've found. I'm sure there are others I didn't find. I don't have a source for some of the irons listed below, feel free to comment a source if you have one. I know there are other Endo forged irons not listed, feel free to comment those and a source for them as well.

Thanks, you're welcome

is the Mizuno 221 223 and 225 not forged in Endo?

Nooo. The forging processes are done in Mizuno's business partner, Chuo Industries Ltd. in Hiroshima Japan. 

I have a set of 2003 RAC Coin Forged irons I picked up recently.  Very well cared for.  Taylormade told me that the irons I have were forged by Endo for Taylormade.  The serial number is on the 5 iron hosel. 

 

I'm a bit curious, but the word was Miura forged these, but the actual club marketer/manufacturer admitted to the forging done by Endo.  

Has anyone heard of this?
