North-South Headscissors

Variety

ヘッドシザーズ(Heddo Shizāzu)

Transliteration

Translation: Head Scissors (katakana loanword)

Overview

The north-south headscissors applies the leg-based head squeeze from the north-south position, where the attacker is positioned head-to-head above the supine opponent. [1] The attacker captures the opponent's head between the thighs while lying in the north-south orientation, then squeezes the adductors to compress the neck. [1],[2] The north-south position provides unique leverage because the attacker's body weight presses downward onto the opponent's chest, limiting breathing and creating multiple pressure points simultaneously. [2] This variant often occurs as a transition when the attacker moves from side control to north-south and catches the opponent's head during the transition. [2],[3]

Also known as
North-South Scissor Strangle[1]Top Position Kubi-basami[2]

History & Origin

North-south headscissors combinations developed in modern submission grappling where the north-south position was explored for offensive potential beyond the standard north-south choke. [1] Competition grapplers discovered the headscissors as a reliable control and submission option from this underutilised position. [2],[3]

Effectiveness

Difficult to secure from north-south position but devastating when locked — the opponent has limited escape options with the attacker's weight stacked on their chest [1]

Lineage

A catch wrestling technique adapted to BJJ; explored by Neil Melanson and other catch-influenced grapplers [1]

Competition Record

Very rare at competition; more of a novelty technique than a primary attack [1]

Biomechanical Mechanism

Primary ActionCompression of the neck structures — restricts blood flow or airway depending on technique application
Joints InvolvedCervical spine, surrounding musculature, and vascular structures of the neck
Force VectorDirected compression against the neck from the choking limb or body position
Finishing MechanicSustained pressure causes either vascular occlusion (unconsciousness) or tracheal restriction (breathing difficulty)

Position & Entry

From guard (bottom position)Use legs to control the opponent's head and arm, lock the leg configuration and apply compression
From mount (top)Transition from mount by isolating an arm and threading legs around the head and arm
From side control (spinning)Spin to face the opponent's legs, throw legs over the head to lock the choke

Variants

Standard north-south chokeshoulder drives into the neck from north-south position
Paper-cutter variationuses the forearm blade across the throat from the north-south angle
Transition finishapplied during the walk-around from side control to north-south

Training Notes

The north-south headscissors captures the opponent's head in a headscissors from the north-south position — the attacker's thighs compress the neck while maintaining top pressure from the head-to-head orientation (Danaher, Pin Escapes and Turtle Turns: BJJ Fundamentals, 2019)
From north-south: instead of or in addition to the north-south choke, capture the opponent's head between the thighs — the north-south angle provides a unique compression vector
The north-south orientation creates a different thigh-to-neck alignment compared to guard headscissors: the thighs press from a more longitudinal angle, compressing the arteries from top
The north-south headscissors is a positional submission: the attacker maintains top control (body weight on the opponent) while the legs create the strangle — dual control and submission
Entry: from north-south control, slide the hips forward until the head is between the thighs, then lock the figure-four
The north-south headscissors is less common than the north-south choke but equally effective when the thigh-to-artery alignment is achieved
The position chains with the north-south choke: if the headscissors doesn't finish, the arm is already near the neck for the standard north-south choke transition

Common Mistakes

!Not sliding the hips far enough forward — the head must be between the thighs, not near the chest; insufficient hip advance leaves the head out of range
!Losing top pressure while adjusting — maintain chest-to-chest weight while sliding the hips forward; lifting up allows the opponent to escape
!Not locking the figure-four — the figure-four is essential from north-south; without it, the opponent can push the legs apart
!Squeezing with knees instead of thighs — target the carotid arteries with the inner thigh surfaces
!Not extending the hips — hip extension from north-south drives the thighs together; without it, the squeeze is purely muscular
!Ignoring the opponent's bridge escape — the opponent will bridge to create space; be ready to ride the bridge while maintaining the headscissors
!Not transitioning to north-south choke if the headscissors fails — the positions are adjacent; flow between them
