The jaw pry face crank from rear mount uses the fingers or hands to pry the opponent's jaw open and to the side, creating cervical rotation stress and intense mandibular pain. [1] From rear mount, the attacker hooks the fingers under the chin or around the jawline and pulls upward and to one side, forcing the cervical spine into combined extension and lateral rotation. [1],[2] The jaw serves as a lever arm — applying force at the jaw creates a long moment arm that transmits torque to the cervical vertebrae. [2] This technique is legal in most grappling rulesets but is considered a crank rather than a choke, and many practitioners tap due to pain rather than loss of consciousness risk. [2],[3]
История и происхождение
Jaw manipulation techniques appear in traditional Japanese jujutsu and European catch wrestling as methods of forcing an opponent's neck into vulnerable positions. [1] The rear mount application became a recognised competition technique in MMA and no-gi grappling where neck cranks are permitted. [2],[3]

Биомеханический механизм
Primary Action — Compression of the neck structures — restricts blood flow or airway depending on technique application
Joints Involved — Cervical spine, surrounding musculature, and vascular structures of the neck
Force Vector — Directed compression against the neck from the choking limb or body position
Finishing Mechanic — Sustained pressure causes either vascular occlusion (unconsciousness) or tracheal restriction (breathing difficulty)
Позиция и вход
From controlling position — Establish the dominant position, clear defensive grips, thread the choking limb into position
From guard (bottom) — Break the opponent's posture, isolate the neck and configure the choke from underneath
From transition — During a scramble or position change, secure the neck control and lock the choke before the opponent re-establishes defence
Варианты
Standard grip variation — primary hand configuration for maximum choking pressure
Gi variation — uses the lapel or collar as an anchor for additional friction and control
No-gi variation — adapted grip and positioning for submission grappling without the gi
Transition finish — applied during a positional change to catch the opponent off-guard

✓The jaw pry face crank uses the fingers or palm to grip the jaw and force the head into rotation or hyperextension — the direct mandibular manipulation creates intense pain and cervical stress (Paulson, Shoot Wrestling, 2007)
✓The jaw pry: insert the fingers under the chin or grip the jaw directly, then twist or lift — the mandible acts as a lever arm that forces the cervical spine to rotate or extend
✓From back control: when the opponent tucks their chin to defend the RNC, the jaw pry opens the neck — fingers grip under the chin and lift the jaw to expose the throat
✓The jaw pry is a transitional technique in BJJ: its primary purpose is to open the chin tuck so that a proper choke (RNC, collar choke) can be established underneath
✓In catch wrestling, the jaw pry is a submission in its own right: sufficient force on the jaw can force a tap from jaw pain or cervical spine stress
✓The technique requires hand strength: the grip on the jaw must be firm enough to overcome the opponent's neck muscles and chin-tuck resistance
✓The jaw pry combines with choke attempts: one hand pries the jaw while the other slides the choking arm into position — a two-part attack that overwhelms the chin-tuck defence
Типичные ошибки
!Using the jaw pry as a violent wrench — the pry should be progressive; sudden jaw manipulation risks TMJ injury and fractures
!Inserting fingers into the eyes or nose — target only the jaw; fingers in the face are illegal in all competitions and dangerous in training
!Relying solely on the jaw pry without transitioning to a choke — the pry opens the chin; immediately follow with the choke as the neck is exposed
!Using the jaw pry from a position without back control — the pry requires stability; from inferior positions, the opponent simply turns away
!Gripping the teeth — grip under the chin or on the jawbone; gripping the teeth risks finger injuries
!Applying the jaw pry in competition where it's illegal — verify the rule set; some organisations prohibit jaw manipulation
!Not recognising when the jaw pry is excessive — if the opponent is in significant jaw pain, they may not be able to verbally tap; watch for physical tap signals

Часто задаваемые вопросы
How dangerous is the jaw pry face crank, and what precautions should I take when practicing it?
The jaw pry face crank is extremely dangerous—applying full power can cause serious injury requiring surgery. According to EffortlessJiuJitsu, you should always practice with control and care, remembering that you only have one spine and want to train jiu jitsu for a long time.
What makes the jaw pry face crank so effective if I'm not using arm strength?
EffortlessJiuJitsu explains that the technique uses body mechanics and hip drive—similar to a deadlift motion—which generates one of the strongest forces the human body can produce, applied directly against the fragile spine.
Can my opponent escape once I have them trapped in this crank?
Once the position is properly set with both arms trapped and the opponent lifted and positioned correctly, they have very limited escape options, according to EffortlessJiuJitsu.
Why is it important to learn this technique even if it's dangerous?
EffortlessJiuJitsu recommends learning defensive knowledge of this technique so you won't be caught off guard if someone else uses it against you.
