The cutting elbow, sok ngat in Thai, is the upward elbow strike that travels from waist height to head height along the centreline of the body. The name ngat literally means to lift or to raise, and the strike functions much like an uppercut — but with the ulna edge instead of the fist as the striking surface. It works at close range, just inside punching distance, and is one of the most reliable ways to open a cut on an opponent's chin, lip, or brow without committing to a long winding strike.
How it works (mechanics)
The cutting elbow starts at the hip. The fighter dips slightly at the knees to lower their centre of gravity, then drives upward by extending the legs and rotating the rear hip forward. The striking arm is folded tightly so the fist sits behind the same-side shoulder and the elbow leads. As the hips rise and rotate, the elbow travels up through the centre, the same line a rear uppercut would follow.
The striking surface is the inside edge of the ulna, two to three inches below the elbow point. Landing on the tip is technically possible but punishing on the fighter's own joint and rarely produces clean cuts. The diagonal upward edge of the ulna catches the underside of the chin, the bottom of the brow, or the lip, where the skin is thin and bone is close to the surface — exactly the geometry that opens cuts.
The support leg, usually the lead leg in an orthodox stance throwing a rear elbow, is bent and rooted, and it does most of the lifting as the strike rises. The off-hand remains high on the cheek as a guard and as counter-rotation.
When to use it (tactical context)
The cutting elbow is the natural answer to opponents who drop their head forward, who duck into punches, or who pressure with their chin tucked low behind a high guard. Common entries include slipping outside a jab and rising with the rear cutting elbow underneath the opponent's lead shoulder, or catching a single-collar tie in the clinch and snapping a short cutting elbow up the centre as the opponent tries to pull down.
It is also a textbook counter to the level change that precedes a takedown attempt or a low kick — as the opponent dips, the elbow rises through the space their head has just entered. Against taller opponents, the cutting elbow is one of the few strikes that lets a shorter fighter reach the chin without first having to close all the way into the clinch.
Common errors
- Throwing with the arm only, with no leg drive, producing a weak rising slap.
- Standing too tall at the start, so there is no upward range left in the legs.
- Letting the off-hand drop on release, opening the chin to a counter.
- Aiming at the forehead instead of the chin or brow, where the cutting geometry is wrong.
Variations and counters
The lead-hand version is faster and works as a check-strike to back the opponent off, while a rear-hand version delivers significantly more force. A short clinch version uses a much smaller hip drive and acts almost as a corkscrewing pry to open space inside a tie. Counters include framing on the biceps to smother the upward path, pulling the head straight back as the elbow rises, or stepping off-line to the outside and answering with a cross over the top of the rising arm.
Who's known for it
Dieselnoi Chor Thanasukarn, the Sky-Piercing Knee, used the cutting elbow to deter opponents who tried to duck under his knees in the clinch. Anuwat Kaewsamrit, the One-Million-Baht Baby-Faced Tiger, was famous for finishing fights with a rear cutting elbow as opponents lowered their head against his pressure. Among current fighters, Petchmorakot Petchyindee uses the cutting elbow as a routine counter to opponents who level-change into his hips.
