Nike Forged Wedges are made from a soft 1030 carbon steel and come with Nike's proprietary groove design - a unique hybrid of U-grooves and V-grooves for just the right amount of spin and distance control. The consistency of forged soft carbon steel eliminates the hot and soft spots in the clubface. It aloows to carefully grind the heel so that the face can be opened without interfering bounce. If you've ever anguished over a lob shot off a bare lie, forget your fret.
