TOP WRISTLOCK (TWL)

The top wristlock (TWL) is the canonical wristlock submission in BJJ, in which the attacker grips the opponent's hand and rotates the wrist past its normal range of motion in the direction the palm faces. The technique attacks the wrist joint by hyperflexing the carpal bones into the radius and ulna, producing a pain submission rather than a structural-injury submission (unlike most BJJ joint locks which threaten ligament damage). The IBJJF restricts wristlocks to brown belt and above; the ADCC permits them at all levels.

The mechanics begin with the attacker gripping the opponent's hand in a specific configuration — palm-to-palm with fingers interlocked, or thumb-to-base-of-thumb in the conventional TWL grip. The wrist is then rotated past its normal range of motion in the direction the palm faces, with the attacker's body weight providing the structural lever. The technique can be applied from almost any position — closed guard, side control, mount, half guard, even standing — because the wrist is exposed in virtually all grappling exchanges. The attacker's challenge is gripping the wrist before the opponent can defend; the technique is most effective when applied to a hand that is already committed to a grip (sleeve, lapel, neck).

Top wristlocks have been used extensively by competitors who specialize in finding submissions from unusual angles, particularly Mikey Musumeci (multiple-time IBJJF World Champion who has built his game around hand-fighting and wristlocks), Eddie Bravo, and the 10th Planet system practitioners. The technique pairs particularly well with closed-guard sweeps and from the bottom of mount/side control. Defensively wristlocks are escaped by recognizing the grip configuration early and rolling the wrist in the opposite direction, by stripping the attacker's grip before the rotation begins, or by tapping early (wristlocks can produce permanent ligament damage if held past the pain threshold).
