Gooseneck

According to Weapons Defense Academy, you want to keep your hand absolutely vertical, not at an angle. Think of it like a praying position—place the opponent's hands between your hands, then apply pressure by pulling their hand toward you while pushing their fingers toward their body.

David Blanc emphasizes that you must keep the opponent's elbow completely blocked—their arm has nowhere to go when the elbow is blocked by your stomach, their back blocks one side, and your forearm blocks the other. Maintaining constant pressure on the collapsed wrist prevents them from straightening it to escape.

The critical factor is keeping the opponent's wrist collapsed, according to David Blanc. Once the wrist is collapsed, you can apply significant pain with minimal strength; if you relax and the opponent straightens their wrist, you lose the advantage unless you're significantly stronger.

Weapons Defense Academy instructs to place your finger where the hand meets the wrist, pull inward with that finger while pushing down toward the opponent's body. Point your finger toward their body and push downward—pushing upward, sideways, or in other directions won't be effective.

The flexion gooseneck wrist lock bends the wrist forward (toward the inner forearm) while curling the fingers backward, creating a gooseneck shape in the flexion direction. The attacker grips the opponent's fingers and palm, pushes the wrist into flexion, and curls the fingers back toward the back of the hand.

Gooseneck flexion locks appear in aikido, traditional jujutsu, and chin na as core wrist manipulation techniques. The technique is widely used in police defensive tactics and security training for pain-compliant suspect control.
