Callaway Opus Platinum Blue Graphite Wedge Very few times in club design can you say a true barrier has been broken. Opus Platinum is a true leap forward in wedge technology, fusing advancements from metal injection molding (MiM), and tungsten for launch control. MiM Construction has opened the door for Callaway to deliver precision in wedge construction like never before, to dial in touch and feel where players need it. Tungsten has been incorporated into the topline bringing the flight lower for more control and spin into greens. MiM Construction for Precise Feel Opus Platinum has been designed through metal injection molding (MiM), using a proprietary blend of metals to precisely dial in performance and feel. This delivers the ultimate in wedge performance, deserving of the Opus Platinum name. Spin Gen Face TechnologyTM for Tour Level Spin Spin Gen Face Technology provides spin and control in your wedges by combining 3 key elements on the face; an all-new tighter pitch which puts more grooves on the face, offset groove-in-groove for spin when opening the face, and a new aggressive face blast providing spin and bite on partial shots. These three elements work in conjunction to provide a crisp, tour level spin. Tour Certified Shaping Opus Platinum wedges are the most Tour-tested, Tour-validated shapes in Callaway history. A higher toe peak, radius in the leading edge, and smoother hosel transitions make Opus Platinum our best wedge shape ever.
