Acceptance came when Julius Boros won the PGA Tour's Phoenix Open, using Solheim's "Anser" putter in early 1967. Later that year, Solheim resigned from G.E., moved his business from his garage to a factory and establish Karsten Manufacturing Corporation (KMC) makers of the Ping brand of clubs in Phoenix, Arizona. The patent for the PING Anser putter came on March 21, 1967. The first major championship to be won using a PING putter came in 1969 at the Masters. In 1969, Ping introduced irons based on the same principle of perimeter weighting, and these were quickly successful. The other golf equipment manufacturers soon followed Ping's innovations, which became industry standards. The last major innovation by PING during the 1960s came with K1 stainless cast steel iron set.
