Tekko-Jutsu (or 前里術 in Japanese) includes the fighting techniques ( 術 Jutsu ) with a pair of Oriental brass knuckles without finger dividers ( 前里 Tekkō ) according to Ryukyu Kobujutsu. Contrary to what is commonly claimed, this weapon was not developed from a pair of horseshoes or a stirrup. Next, Kihon (or 基本 in Japanese) means basics or fundamentals. In this video (recorded on 8 April 2024), budoka Johan Oldenkamp, a former national champion from the Netherlands, performs these basic fighting techniques with the Tekko, starting with the right fist, then the left fist, and finally with both fists at the same time.
