The Mizuno MP-60 Cut Muscle Cavity iron continues to maximize the performance for today's more aggressive game. The Grain Flow Forged MP-60 is 4% larger and has a 10% larger sweet area when compared to its outstanding Cut Muscle counterpart, the MP-32. The Cut Muscle design in the Mizuno MP-60 delivers a slightly higher ball flight in the long irons, and a mid trajectory in the scoring irons, while the Cut Muscle design precisely positions the COG in each club for a consistent and predictable ball flight. The MP-60’s feature an innovative Cut Muscle Cavity design that provides ideal COG locations, perfect trajectory, enhanced solid feel and increased forgiveness. The grain Flow Forged, 1025 select mild carbon steel provides the ultimate soft, solid, consistent feel. They come with a durable double nickel chrome plated finish and modified U-grooves produce the ideal spin rate for maximum playability in all conditions. Rolled leading edge, cambered mid-sole, and rolled trailing edge deliver consistent striking ability from all types of lies.
