Abstract
The head and shaft of golf clubs are mechanically isolated from one another by a dampening ferrule made of a rubber-like material and installed around the shaft where the shaft attaches to the head such as at the hosel. The ferrule in a disclosed embodiment is configured as a hollow cylinder having an internal passage for tight-fit engagement with the shaft and an external radial surface for tight-fit engagement with the golf club head. Preferred materials for the dampening ferrule include Neoprene, Delrin, Nylon, plastic polymers and other rubber-like substances.
