TaylorMade Milled Grind 4 Raw Design Matt Black Wedge With MG4 TaylorMade have evolved their approach to wet spin and developed an all-new Spin Tread technology. They use a laser etching treatment to create face roughness, which translates to better friction and moisture channeling for optimal ball control, especially on partial shots. Spin Tread Groove Deep laser etching between the grooves provides a channel for the water to escape upon impact, maintaining spin in wet conditions. Increased Flange Thickness This design offers improved sound and feel on shots struck across the face. Raw Face The raw surface and toe area works in conjunction with new Spin Tread Grooves to provide the best spin properties in wet conditions. Improved Tour Inspired Shaping The reshaped top line, leading edge and hosel blend to create a smoother and fuller look for improved shot making. Lighter Weight Tour Issue Shaft A light True Temper Tour Issue 115g shaft helps generate more feel. Machined Sole A fully machined sole ensures the exact grind and bounce geometry every time.
