Forged from premium 1025 carbon steel and CNC milled, using all the successful fundamentals of the original M-Craft models, the OMOI putters feature a heavier head weight to increase MOI for improved stability. The OMOI achieved its new stability by taking a view of the entire club – balancing out the increased headweight with a lighter weight grip and shaft to shift the club’s CG and help control face rotation through the putting stroke.
