<HTML>I have a custom Renner/Keith Bowan model. This is the one that is made of brass, stainless steel, and rosewood. Keith is known for making some of the best tuning hammers in the industry.   Most of the Renner hammers are made by him.   I was having severe shoulder problems and thought that susing an impact hammer would help....it didn't.  My problem was caused by a bone spur in my shoulder socket.  So, using the impact hammer did not help.  Mine cost 230.00, and is in pristine condition.  I will sell it for 190.00.
