Toru Kamatari founded Sonartec Golf in 1999 with cutting-edge hybrids designed for greater distance and with larger sweet spots than had ever been seen before. This technology had been licensed from Royal Collection Golf, a popular Japanese club manufacturer. Sonartec’s woods, such as the SS-07 and MD hybrid, quickly attracted a following among PGA Tour golfers and serious amateurs. The company put its focus on custom-fitted clubs for advanced players and saw demand rapidly rise through the mid-2000s. Unfortunately, ownership disputes and production shortages derailed the company’s fortunes, and it is no longer in operation. However, T35 wedges and SS-Series irons remain popular to this day, paving the way for Royal Collection to reintroduce its proprietary club technology the US in 2011.
