Based on our masterpiece N.S.PRO WV, which was designed exclusively for wedges and thoroughly refined for operamtional ease, as well as feedback from PGA tour players, Nippon Shaft crafted a new steel shaft for wedges that offers first class short game performance. N.S.PRO's proprietary wall thickness adjustment technology contributes to high-level stability (in terms of spin and direction) while MHT (Multi Heat Treatment) technology, our cutting-edge heat treatment for MODUS 3 series shafts, delivers the comfortable feeling you expect of short game gear.
