Odyssey Black Series TD 2Ball Blade Putter Milled from 1025 carbon steel for soft feel, with a urethane-dampening layer subtly placed between the head and the tungsten flange, which enhances sound and feel. A.R.T (Advanced Roll Technology) uses multi-material construction for lower, deeper CG to promote better, quicker and truer roll. Deep Black PVD (Physical Vapor Deposition) Finish produces a durable, non-glare look that was added based on feedback from Tour players. TD Milled Face features a deeper, sharper milling pattern for increased interaction between the face and ball, providing better feel, roll and consistency.
