Sledgehammer
The Sledgehammer is a move commonly used in F2L pair insertion. When an edge pair that needs to be inserted rests on the left of right face of the cube relative to the face towards you, and the cross color is facing away, usually you would have to do a cube rotation and insert it using either U' L' U L on the right or U R U' R' on the left. Instead, you could utilize the sledgehammer, which, without a cube rotation, goes F R' F' R on the right or F' L F L' on the left.
