Calf Slicer

The Calf Slicer, also known as a Calf Crusher or Knee Compression Lock, is a powerful submission that applies intense pressure to the opponent's calf muscle by compressing it against their shinbone. This submission is considered a pain-compliance or muscle-compression technique, but it can also damage ligaments or tendons around the knee if applied with excessive force.

Key Concepts

Compression Lock

  • The Calf Slicer uses the opponent's leg trapped against a hard surface, such as your arm or shin, to generate intense pressure.

Leverage

  • Proper body positioning amplifies the force applied to the opponent's leg.

Control

  • Securing the opponent’s leg and hip movement is crucial to prevent escape and increase the effectiveness of the submission.

Execution Steps

Isolate the Leg

  • Trap the opponent’s leg so their shin is pinned against your forearm or shin.

Control the Opponent’s Hip

  • Prevent them from escaping or relieving pressure by controlling their hip with your arms, legs, or body position.

Create the Compression

  • Pull or push the opponent's leg into the hard surface, compressing their calf muscle against their shinbone. The pressure should focus directly on the muscle and the knee joint.

Lock the Position

  • Use your legs or arms to maintain tight control over their leg, ensuring they cannot escape or shift their position.

Apply Pressure

  • Gradually increase the force to elicit a tap. Use your hips or arms to amplify the compression.

Common Entries

From De La Riva or Open Guard

  • Use the opponent's leg positioning to trap their shin against your shin or arm.

From Half Guard

  • Transition into a Calf Slicer when the opponent extends their leg or tries to pass your guard.

During a Leg Lock Attempt

From Back Control

  • When you lose back control, you can switch to the Calf Slicer by trapping one of their legs.

During a Scramble

  • In dynamic exchanges, trap the opponent’s leg as they post or move.

Guard Pass Defense

From X Guard or Single-Leg X Guard

  • Use the opponent’s positioning to isolate their leg and attack the calf.

Tips for Success

Control Their Hips

  • Prevent the opponent from escaping or rolling out by dominating their hip movement.

Isolate the Leg

  • Keep the opponent’s leg tightly trapped to maintain pressure.

Adjust Your Angle

  • Align your body to maximize compression and reduce the risk of escape.

Use Leverage

  • Incorporate your entire body, especially your hips, to increase the force applied to the submission.

Positioning

The Calf Slicer is most effective in positions where you can control the opponent’s Fundamentals/Base and hips while isolating their leg. Tight connections and proper angles are essential for successfully applying this compression lock.

From Half Guard

  • Use the opponent’s extended leg to trap their shin against your arm or shin as they attempt to pass.
  • Transition into the slicer when the opponent posts their leg to create space.

From De La Riva or Open Guard

  • Trap the opponent's leg during sweeps or guard retention to set up the slicer.
  • Transition into the slicer when the opponent shifts their weight forward, leaving their leg exposed.

From Back Control

  • If the opponent defends the Rear Naked Choke or peels off your Hooks, isolate one of their legs and transition into the slicer.
  • When losing back control, attack their leg as they turn to escape.

From Butterfly Guard

  • Sweep the opponent forward and trap their leg as they post, transitioning into the Calf Slicer.

From X Guard or Single-Leg X Guard

  • Use the opponent’s leg positioning to trap their shin while elevating their body, transitioning into the submission.

From Mount Bottom

  • Trap the opponent's leg as they step up or post during an escape attempt.

From Side Control Bottom

  • If the opponent's leg is close during a scramble, isolate their shin and pivot into the Calf Slicer.

During Takedown Defense

From Turtle Control

  • Trap the opponent’s leg as they attempt to recover guard or roll out of turtle position.

From Guard Passing

From Scrambles

  • In dynamic exchanges where the opponent’s leg is extended, quickly trap their shin against your forearm or shin to set up the slicer.
