The TR47 set of clubs includes a 19° 3H and a 22° 4H equipped with UST Mamiya V2 graphite shafts. The 5-iron through sand wedge are cast from 17-4 stainless steel that is heat-treated for better corrosion resistance and more strength. A rubber compound cell behind the face reduces unwanted vibrations, while the stock shafts are Rifle Project X in steel.
