The Dynacraft Prophet MB (Muscle Blade) irons are a blade head, yet designed for game-improvement. It's a design where the technology is hidden. First, a hollow-bodied design moves weight to the perimeters for exceptional forgiveness similar to a hybrid. Also in this multi-material design, there is an ultra-thin, high-strength cup face to increase ball speed and maximize distance. The weight saved by the face design is positioned low and back for perfect launch conditions. With all this technology, the heads still have the traditional appearance. This is truly a game improvement iron head for golfers of all abilities.
