片羽絞(Kata-ha-jime)
TraditionalTranslation: Single-Wing Strangle
The one-wing collar choke combines an underhook through the opponent's armpit ('wing' control) with a cross-collar grip on the opposite side to create an asymmetric strangle from back control or mount. [1],[2] The underhook arm threads under the armpit and reaches the collar, while the choking hand grips the far collar across the neck. [1],[3] The wing control traps one defensive arm and anchors the attacker's position, while the collar grip applies the primary choking pressure. [1] This creates a highly controlled position where the opponent has only one free hand to defend. [2],[4]
The one-wing collar choke derives from judo's kata-ha-jime (片羽絞め, 'single wing strangle'), a classical shime-waza combining arm trapping with collar strangulation. [2],[3] Kata-ha-jime was codified in the Kodokan's katame-waza curriculum and has been a competition staple in judo. [2] BJJ refined the technique for modern back control systems where trapping one arm is a standard step toward securing the choke. [1],[4],[5]
The one-wing collar choke uses a single deep collar grip combined with the opposite hand framing against the opponent's arm. [1]
One-wing collar chokes are used in gi BJJ competition as a variation on standard collar choke attacks. [1]

The one-wing collar choke is a back-control submission that emphasizes securing a dominant grip on the opponent's lapel before executing the finish. Code 4 Concepts Chad Lyman describes the technique as beginning with proper back mount positioning, where the attacker's top-side arm is hidden in the opponent's armpit to protect the grip during hand-fighting. The critical first step is obtaining the "first relevant lapel grip" with thumb inside and fingers outside, a position Lyman treats as the foundation for multiple finishing options. Once secured, the primary single-wing variation involves falling to the side with the lapel grip to complete the choke. Lyman demonstrates that if the opponent escapes, the same lapel grip can chain into alternative submissions including stacked double-lapel tilts, bow-and-arrow chokes, and clock chokes, emphasizing that grip retention is essential throughout transitions. Gracie Barra O'Fallon presents the single-wing choke from a mounted or seated-mount position, where the attacker feeds the gi collar (thumb in, wrapping through the hand hole), passes it across with the second hand, and finishes by sitting up and driving the hips forward. Stuart Tomlinson (via Rene Dreifuss) addresses the physiological mechanism of choking generally, explaining that unconsciousness results primarily from pressure on the baroreceptor nerve rather than oxygen deprivation, and that rotational shear force combined with head misalignment and radius bone pressure is more effective than pure squeezing. All three instructors agree on grip security and technical precision, though they differ in positional context—back mount versus mount position.

Your hand should be in a 'rev on' position (like revving a motorcycle) behind the neck and under the chin, with your thumb in and pinky on for a solid grip. Avoid bowing your hand forward, as this weakens the choke—instead, snap your hand back for proper pressure. (Gracie Barra O'Fallon)
A common mistake is leaving your top-side arm in the middle where your opponent can control it. Instead, hide that arm in their armpit and reach it across so your other hand goes on top, giving you a better chance to clear their grip when they fight. (Code 4 Concepts Chad Lyman)
Feint an armbar while maintaining your collar grip, then transition to a bow and arrow choke or any of its variations. This keeps your opponent committed to defending the wrong technique. (Code 4 Concepts Chad Lyman)
Once you establish your grip, never give it back unless you're intentionally trading it for another grip—your opponent will follow you wherever you go. (Code 4 Concepts Chad Lyman)

Standard counters include: Tuck Chin — protect the neck by lowering the chin to prevent the choke from sinking / Two-on-One Grip Fight — use both hands to strip the choking grip before it locks / Turn Into — rotate toward the choking arm to relieve carotid pressure / Posture Up — straighten the spine and create distance to break the choking angle.
