While still known for its pro-level utility woods, hybrids and solid economy drivers, Nickent Golf inched its way into the premium iron market in 2006, with the 3DX Pro series. Each club blends cavity- and muscle-back technology and the classic look and feel of a blade. The 3-iron through pitching wedge set is marked by each club's tungsten-polymer insert, medium-sized top line and traditional blade length. The irons, now discontinued and succeeded by the 4DX Pro Series, were stocked with heat-treated Nippon 1180 steel shafts. These irons are still available through select retailers in the $200 to $250 range. A graphite option is also available.
