Three

셋 (set) is the native Korean word for the number three. It belongs to the series 하나 (hana), 둘 (dul), 셋 (set), 넷 (net), which is used to count people and things. Before a counter it takes the form 세 (se).

In kumdo, the Korea Kumdo Association (대한검도회) textbook uses the count in step-by-step strike drills. In the 3동작 정면 머리치기 (three-count straight head strike), on 「하나」 (one) the bamboo sword (죽도, jukdo) is raised to about 45 degrees above the head. On 「셋」 (three) the body steps back, the sword tip is drawn back as if scraping down the opponent's face, and the practitioner returns to the middle guard (중단, jungdan).

A press article on training says that in the 3동작, 2동작 and 1동작 drills the count «하나», «둘», «셋» is called out loudly. Strike drills are learned starting with the three-count form (3동작), then the two-count (2동작), the one-count (1동작) and the quick strike.
