Also known as a Calf Crusher, it is a compression-type submission hold that involves pressing the calf and/or thigh muscle into one of the bones in the leg. It can be applied by inserting an arm or leg in the backside of the knee, and flexing the opponent's leg to apply pressure to the muscles surrounding the fulcrum. Generally, the direction of the shin in the leg acting as a fulcrum will determine where the larger part of the pressure will go. Such calf slicers can be used as effective leg locks to the knee through a separating and elongating motion. The calf slicer is listed as a banned technique in the lower levels of some major Brazilian jiu-jitsu competitions. WWE Wrestler AJ Styles uses this as one of his finishers, calling it the Calf Killer in New Japan Pro Wrestling and TNA and the Calf Crusher in WWE.
