Elbows
The elbow is meant to cut the opponent skin and draw blood. It is used as a sharp razor, as the tip of the elbow, not the all arm, should hit the target. Therefore the aim is not at hitting bruntly, but to quickly scratch the target, like a sheet of paper going swiftly through the flesh. Unfortunately, spectacular elbows KO's are nowadays quire rare. There are eight kinds of elbow strikes: sok ti (striking elbow), sok tat (cutting elbow), sok hut (levering elbow), sok chieng (diagonal elbow), sok sap (choping elbow), sok tong (pull down elbow), sok kuu (double embow), sok klap (reverse elbow).
