Can Opener BJJ? A Deep Dive into This Controversial Technique

The “Can Opener” in Brazilian Jiu-Jitsu (BJJ) is a submission targeting the neck by pulling the head towards the chest. While it can be highly effective, its application is often controversial due to the potential for injury, particularly to the cervical spine.

Understanding the Can Opener in BJJ

The “Can Opener,” technically a cervical lock, is a technique where a grappler uses their hands to force their opponent’s chin towards their chest, creating pressure on the neck. It’s generally considered a more aggressive submission than chokes or joint locks, and its use is often debated in BJJ circles due to safety concerns.

The Mechanics of the Can Opener

The effectiveness of a can opener relies on the leverage and precise application of pressure. Here’s a breakdown of the key mechanical aspects:

Control: The attacker must maintain a solid base and control of the opponent’s posture to prevent escape. This often involves securing their opponent’s arms or legs.
Grip: The grips are crucial, typically involving placing one or both hands behind the opponent’s head. Variations include palm-to-palm grips, gable grips, or grips on the back of the neck.
Pressure: The attacker then pulls or levers the head forward, forcing the chin towards the chest. The pressure must be controlled to avoid excessive strain on the neck.
Leverage: Using the attacker’s own body weight and positioning further amplifies the pressure. This could involve bridging, shifting weight, or using leg leverage.

Potential Benefits of the Can Opener

While controversial, proponents argue that the can opener offers several potential benefits:

Breaking Posture: The primary use is to break down the opponent’s posture, making it easier to pass their guard or secure other submissions.
Submission: Applied correctly, it can force a submission due to the pain and pressure on the neck.
Control: It can be used to control an opponent who is turtling or defending aggressively, allowing you to transition to more advantageous positions.

The Risks and Controversies

The most significant concern surrounding the can opener is the potential for serious injury. The cervical spine is vulnerable, and improper application can lead to:

Muscle strains and sprains: These are the most common injuries, resulting from sudden or excessive pressure.
Nerve damage: Severe pressure can compress or damage nerves in the neck, causing pain, numbness, or weakness.
Disc injuries: The intervertebral discs can be damaged or herniated, leading to chronic pain and limited mobility.
Spinal cord injury: Although rare, excessive force could potentially damage the spinal cord, resulting in paralysis.

Due to these risks, many BJJ gyms and competitions restrict or prohibit the use of can openers.

Safe Training Practices

If can openers are allowed in your gym, prioritize safety with these guidelines:

Start slow and controlled: Apply pressure gradually and communicate clearly with your training partner.
Tap early and often: Don’t hesitate to tap if you feel any discomfort or pain in your neck.
Focus on technique, not strength: Proper leverage and body positioning are more effective than brute force.
Train with experienced partners: Partners who understand the risks and are committed to safe training.
Avoid using it on beginners: Beginners may not have the neck strength or awareness to defend properly.

Legal Considerations

Using a can opener improperly in a sparring or competition setting could lead to legal repercussions, especially if it results in serious injury. It’s crucial to be aware of the legal implications and potential liabilities.

Positions Where Can Opener Is Most Often Applied

While the can opener can be attempted from various positions, some are more common and conducive to its application:

Back Control: From back control, it is easier to secure head and neck control.
Turtle Position: When the opponent is turtled, creating space to leverage the head is easier.
Mount: From the mount, control is easier to maintain.

Alternatives to the Can Opener

Given the risks, consider these safer alternatives that achieve similar goals:

Neck cranks: While still targeting the neck, focus on twisting motions rather than direct compression. These should be approached with similar caution as can openers.
Chokes: Prioritize blood chokes or air chokes, which are generally considered safer submissions.
Posture breaking guard passes: Focus on disrupting the opponent’s base to pass the guard.

Effectiveness of Can Openers in Competition

The effectiveness of can openers in high-level BJJ competition is debated. While they can be used to control the opponent and set up other attacks, they are rarely seen as primary submission finishers due to their inherent risk and the skill of experienced grapplers in defending against them. Often, its use is as an intimidation tactic to force the opponent to open up.

Common Mistakes When Performing Can Openers

Using excessive force: This is the most common and dangerous mistake. Control and leverage are key, not raw strength.
Applying pressure too quickly: Gradual pressure allows the opponent to tap before serious injury occurs.
Neglecting body positioning: Proper body positioning maximizes leverage and control, reducing the need for excessive force.
Ignoring the opponent’s reaction: Pay attention to your partner’s response and adjust your technique accordingly.

Frequently Asked Questions (FAQs)

Is the can opener legal in all BJJ competitions?

No, the legality of can openers varies significantly depending on the ruleset and the specific competition. Many competitions ban them outright due to safety concerns. Always check the rules before using this technique.

What are the best grips to use for a can opener?

There isn’t a single “best” grip, as it depends on the position and individual preference. Common grips include palm-to-palm, gable grips, and grips on the back of the neck. Experiment to find what works best for you.

How can I defend against a can opener?

Defending against a can opener requires maintaining good posture, protecting your neck, and creating space. Bridge away from the pressure, tuck your chin, and use your arms to create distance.

Are can openers more effective against beginners or experienced practitioners?

Can openers are generally more effective against beginners who may lack the neck strength, awareness, and technique to defend properly. Experienced practitioners are better equipped to defend and escape.

Can a can opener cause permanent damage?

Yes, if applied improperly or with excessive force, a can opener can cause permanent damage to the neck, including nerve damage, disc injuries, and, in rare cases, spinal cord injury.

What should I do if I feel pain in my neck while someone is applying a can opener?

Immediately tap out. Ignoring the pain could lead to serious injury. Your health and well-being are more important than winning a match or sparring session.

Are there any specific stretches or exercises that can help strengthen my neck and prevent injuries from can openers?

Yes, regular neck exercises can help strengthen the muscles around the neck and reduce the risk of injury. These include neck extensions, flexions, lateral flexions, and rotations.

Is the can opener considered a “dirty” technique in BJJ?

This is a subjective question. While some consider it a legitimate technique with strategic applications, others deem it “dirty” due to the high risk of injury. Ethics varies across gyms and individual perspectives.

How important is body positioning when applying a can opener?

Body positioning is crucial. Proper positioning allows you to maximize leverage and control, reducing the need for excessive force and minimizing the risk of injury.

Are there any alternatives to the can opener that achieve similar results but are safer?

Yes, there are safer alternatives, such as chokes, neck cranks (used with caution), and posture-breaking guard passes.

Should children be allowed to train can openers in BJJ?

Generally, it is not recommended for children to train can openers due to the increased risk of injury to their developing spines.

What is the long-term impact on the neck for those who use or are subjected to the can opener frequently?

Frequent use or subjection to the can opener can lead to chronic neck pain, stiffness, and potential long-term damage to the cervical spine. Consistent safe training practices are vital.
