The Kushin putter was designed to work exactly as it sounds. The "floating face" of the putter head suspended between the toe and sole (and separated by a thin slot) provided a cushioning effect between putter and ball.

This Kushin putter bears a patent number in the cavity on the back of the head, along with the manufacturing address of Ping Golf Clubs in Scottsdale, AZ—the address for Karsten's garage operation and headquarters! The sight line on the top of the head is original to the club,  The 35" shaft has Karsten's "Z-Bend," devised after the USGA ruled his two-way bent grips were illegal.  The shaft still includes its original shaft band and an old inventory label.  The black Golf Pride Pro Only grip appears original.
