Ben Hogan Carnoustie Wedge. Ben Hogan Carnoustie wedges feature a tungsten EDM force coating and the CNC (Computer Numerical Control) milled U-shaped grooves with radiused edges. The precision milled club face provides a perfectly flat hitting surface that allows greater consistency and shot-making. The pulled heel grind and bevelled trailing edge allows the leading edge to stay close to the ground when laying the blade open.
