Engineered for skilled players, the rac MB is a coin-forged, muscleback blade that incorporates TaylorMade's unique rac technology, which controls and tunes the feel of each club through the shape and location of Feel Pockets positioned in the back of the clubhead. Beyond great feel, the rac MB was engineered to offer the best possible combination of workability and looks available. It benefits from its coin-forged method of production, a forging process wherein, after traditional double-striking, the forged steel is slowly compressed between two dies, which precisely forms the steel into the shape of a clubhead. The advantage of coin forging is that the resulting clubhead is both exceedingly beautiful and extremely consistent in detail. Features of the iron include a forward centre of gravity for maximum workability from right-to-left, left-to-right, a narrow sole that performs from all lie conditions combined with a blunt leading edge that resists digging. The rac MB's great looks are the result of a slim top-line preferred by tour pros and skilled amateurs in a traditional, smaller head-size and profile with a highly polished, nickel-chrome-plated finish and a progressive offset from long-irons to wedge.
