Grandmaster Haim Zut took part in the first Krav Maga civilian instructor course held by founder Imi Lichtenfeld in 1963. Haim was one of four students of Imi's to attend this course. He received his license to teach martial arts from the Wingate Institute (required in the state of Israel) and began teaching classes. Haim's first class was in Hadera, and from that point on he would train students in Hadera, Pardes-Hana, and Gan Shemu'el (where Rhon Mizrachi began his training). As Imi's student Haim was one of the "original 8" members of Imi's Krav Maga organization.

The founders of the federation were: Imi Sde'Or (President), Barak Yehoshua (Head of the Professional Committee), Tsvi Morik (Secretary), Haim Zut, Eli Avigzar, Rafi Algrisi, Haim Gidon, and Oskar Klein.

Haim continued to gain proficiency, not only by advancing in ranks but also by studying for additional teaching licenses from the Wingate Institute. In 1980, Haim took part in an instructor licensing course at the Wingate Institute for certification as a martial arts coach, the equivalent of an Olympic-level trainer, and received his 6th Dan rank from Imi.

In the late 1980s, power struggles began to become commonplace within the Israeli Krav Maga Association. High ranking instructors began to splinter away, taking their students with them. In 1993, Haim left the Israeli Krav Maga Association to create the Association of Krav Maga International-Kapap. He had become frustrated by the internal politics of the organization, and with the blessing of his long time mentor and friend, Imi Sde'Or, he decided to distance himself from the infighting in order to focus on training his students.

In 2003, the leading coaches and masters of fighting arts in Israel decided to honor Haim with the rank of Dan 10 because of his contribution and work within the community of martial arts in Israel. At the same time, he was inducted into the martial arts Hall of Fame and, in 2006, he was given the title of Grandmaster in recognition of over forty years of teaching.
