Can Opener

Submission
Also known as:
Neck Crank From Guard

The can opener is a neck crank applied from closed guard top by clasping both hands behind the opponent's head and driving their chin toward their chest while posturing upward with the hips. It attacks the cervical spine and can also be used strategically to force the bottom player to open their closed guard, creating passing opportunities.

Quick Reference

Key principles

  • · The leverage comes from driving your hips forward and upward while pulling the head down, creating opposing forces on the spine.
  • · Locking a tight Gable grip or S-grip behind the crown of the head, not the neck, maximizes cranking pressure on the cervical vertebrae.
  • · Keeping your elbows tight to your body prevents the opponent from swimming their arms inside to break your grip.
  • · Anticipate the opponent opening their guard to relieve pressure—be ready to immediately pass or transition rather than chasing only the submission.
  • · Stacking your weight forward over the opponent reduces their ability to create distance or re-angle their hips to escape.

Execution

  1. 1 From closed guard top, establish a strong Gable grip or S-grip behind the crown of the opponent's head, pulling it off the mat.
  2. 2 Tuck your elbows tight against your torso and begin driving your hips forward while pulling the opponent's head forcefully toward their own chest.
  3. 3 Posture up and stack your weight over the opponent, compressing their neck by creating maximum separation between their hips and head.
  4. 4 Maintain constant forward hip pressure and squeeze your grip tighter to finish the crank, or capitalize immediately when they open their guard to relieve pressure.

Common mistakes

  • × Gripping behind the neck instead of behind the crown of the head, which drastically reduces leverage and allows the opponent to posture-fight effectively.
  • × Pulling with the arms only without engaging hip drive forward, resulting in insufficient force to finish or open the guard.
  • × Failing to transition when the opponent opens their guard to relieve pressure, wasting the primary strategic benefit of the technique.
