It is a defense against a rear right hammerlock placing it in the Chokes & Locks category in the Web of Knowledge and a member of the Locks family group in the Chokes & Locks category of the grappling division.

Additional Information


The term wing in American Kenpo is synonymous with the elbow joint. In this case the attacker is applying a right hammerlock on your right elbow (wing), thus the name Locked Wing.


The ideal phase places your opponent directly behind you. Your opponent then grabs your right wrist with his right hand (palm up) and pushes your wrist up your back.

A hammerlock can be applied several ways, with the palm up method being the most common.  A hammerlock is mostly used to subdue and control the victim. While in a hammerlock you need to be aware of an additional attacker or being run up against an object such as a wall.  By itself, the hammerlock can cause excruciating pain in the shoulder, tear the muscles, tendons, cartilage as well as dislocate the shoulder.

Historical Versions

1975 Accumulative Journal

LOCKED WING (hammerlock)

  1. With opponent locking your right arm, step back and to your right (between 4 and 5 o’clock) with your left foot into a right neutral bow (with your head still looking forward to 12 o’clock) as your right hand counter grabs your opponent’s right wrist. (Try to place your left leg inside and against opponent’s right leg.)
  2. Immediately pivot your entire body counter clockwise into a left neutral bow (facing 6 o’clock) or horse depending on circumstance, as you deliver a left back horizontal elbow strike to opponent’s jaw.
  3. Circle your left arm over and under opponent’s right elbow as you pivot to your right (toward 10 o’clock) in a modified horse.
  4. While still applying pressure on opponent’s left elbow, drop back with your right foot (between 4 and 5 o’clock) and form a left forward bow.
  5. Immediately release your right hand as you deliver a right knee kick to opponent’s chest with a right overhead heel of palm strike to the back of opponent’s neck thus causing a sandwiching effect.
  6. Follow through by stepping forward toward 11 o’clock with your right foot into a fighting stance.




  1. I think there is a hidden problem with this technique and its on the part of the attacker.

    When coming from behind, the attacker can grab your wrist with his hand set with palm facing you or his hand inverted and palm facing away. People usually grab palm in and end up with your arm behind your back and their palm up and this is a weak grab and the position I think this technique is intended to address with the right hand counter-grab. The counter grab is in a superior control position (after all, we don’t want the sucker, I mean attacker, to get away, right?) and anchors the attacker’s arm to your back as you unwind into the elbow strike and over-and-under uppercut.

    Now, if the attacker comes in hand inverted, he ends up with your arm locked back and his palm *down* in a superior control position. This makes executing the technique harder but you won’t know that until you try for the counter grab and he counters you by wrenching your arm further upward.

    Another thing to watch out for is the attacker’s left hand. Hammerlocks are basic come-along techniques and the left hand is usually on your shoulder or in your hair to direct you where to go. If the left hand is applied to the back of your right hand, he is going for a gooseneck-style wrist lock. A sure sign that this is the case is when the right control hand slides down your arm to cup your right elbow. At that point, the attacker pretends your arm is an accordion and pushes inwards, causing major pain in your right wrist.
