Overview
History & Origin
The chop strike, delivered with the edge or flat of the hand in a downward or diagonal arc, appears across numerous martial traditions worldwide. [1] In karate, chopping techniques are classified under uchi (strikes) and include both knife hand and ridge hand variations. [2] Western military combatives adopted the chop as a practical close-quarters weapon, with Fairbairn's World War II manual recommending edge-of-hand blows to vulnerable targets such as the neck and collarbone. [3] The chop was popularised in Western culture through early martial arts films and television, though its combat application has remained a staple of self-defence systems. [1]

โThe chop strikes with the outer edge of the open hand (knife hand) in a downward or diagonal arc
โDrive the chop from the shoulder with a hatchet-like motion, tightening the hand at the moment of impact
โTarget the neck, collarbone, or the side of the neck where the carotid artery and vagus nerve run
โThe chop is primarily a self-defence and traditional martial arts technique โ it is less common in sport fighting
โIn combatives training (Fairbairn, Sykes, Applegate), the chop to the side of the neck was taught as one of the most effective close-quarters strikes
โKeep the fingers together and the thumb tucked to create a rigid striking edge
โThe chop can be thrown from standing or as a ground-and-pound technique from top position
Common Mistakes
!Hitting with the fingers extended and loose, which causes jammed or broken fingers on impact
!Slapping with a floppy hand instead of striking with a rigid edge โ the hand must be taut at contact
!Aiming at the top of the head where the skull deflects the strike โ target the soft neck, collarbone, or temple
!Using excessive windup, which telegraphs the chop and slows delivery
!Not tightening the hand at the moment of impact โ the hand transitions from relaxed to rigid at contact
!Chopping at a flat horizontal angle when a downward diagonal would be more effective against the neck
!Using the chop in sparring or competition where it may be illegal โ check the rules

Frequently Asked Questions
Why is footwork important when executing a chop?
Footwork is crucial because moving only one foot while keeping the rest of your body stationary leaves you vulnerableโyour opponent can still strike your shoulder or other parts of your body. You need to move your entire body, including your head and shoulder, to properly evade the counter-attack.
How do I prevent my opponent from catching my follow-up hand after I strike?
Keep your other hand ready to lock out your opponent's reach. If you control your leg positioning and maintain defensive hand placement, it becomes very difficult for your opponent to catch you or reach you from alternative angles.
How does the Chop work?
