Introduction to Finger Locks

Finger joint locks represent a category of techniques in jiu-jitsu alongside wrist and arm locks. The instructor demonstrates multiple finger lock variations beginning from a same-side wrist grab position.

Inverted Arm Bar with Finger Pressure

From a same-side wrist grab, the practitioner swings their arm around and inverts the opponent's arm to apply pressure on the wrist and fingers by driving toward the opponent's center. Additional pressure can be applied to the triple warmer 11 pressure point above the elbow while simultaneously pressuring the hand and wrist upward.

Opposing Directional Pressure Principle

Finger locks typically employ simultaneous opposing movements, with pressure applied in one direction while force is applied in another. This dual-direction mechanic increases the effectiveness of the lock.

Single Pinky Finger Lock

The practitioner reaches over the opponent's grip to isolate the pinky finger, placing fingers at the pinky's joint. The base hand creates stability while pressure is applied downward with the ring and pinky fingers, with the pointer finger directed toward the opponent's center and driven downward as the base hand pushes upward.

Multiple Finger Lock Variation

Rather than isolating a single finger, the practitioner can control multiple finger joints simultaneously—combining the pinky with the three adjacent fingers into a single lock. The same opposing pressure mechanics apply, with one hand driving upward while the other pressures the joints downward toward the wrist.

Upper Hand Joint Lock

A finger lock can be applied to the upper joints of the hand by creating a base and driving pressure directly back toward the opponent's center. The technique can transition into an inverted IQ position by driving the fingers upward while maintaining arm control at a 90-degree angle.

Transition to Hammer Lock

From the inverted IQ position, the practitioner can slide into a hammer lock by driving the hand into the crook of the opponent's elbow and securing the wrist against the chest. This transition maintains upper body control while opening options for further technique application.

Wrist Inversion with Three-Joint Control

When an opponent grips in certain positions, the practitioner can invert the wrist and slide fingers around all three joints of the opponent's fingers while applying thumb pressure to the back of the hand. This configuration creates an efficient and accessible finger lock.

Individual and Multiple Finger Targeting

Finger locks can target individual fingers by placing the pinky at the base of the joint and wrapping with the remaining fingers, or multiple fingers can be controlled simultaneously using the same mechanism. The pointer finger is consistently oriented toward the opponent's center while the base hand creates stability.

Thumb Lock Application

A thumb lock is executed by wrapping the ring finger at the thumb's base and positioning the attacking hand's thumb on top of the opponent's thumb. Pressure is driven straight back toward the opponent's center while the base hand provides support and counter-pressure.
