The International Federation of Karate (IFK) is an international organisation with over 50 member countries, headed by Hanshi Steve Arneil, and managed by an international board. Hanshi Arneil was the first person to do the 100 man kumite after Mas Oyama did his 300.
The IFK was formed in 1991 by Hanshi Arneil, and is based in the UK but has members on every inhabited continent. They have organised several successful World Tournaments (junior, senior, and kata), the iconic annual British Open, several international Black Belt camps with over 100 black belts attending from 1st dan to 7th dan, and the senior members are regular instructors at international camps all over the world, including Australia.
The IFK has a structured syllabus that takes you all the way to 3rd dan. The basis of this syllabus was put together by Hanshi Arneil, and it still forms the basis of a lot of syllabi, even non-IFK ones, in Europe and elsewhere. With each grade, you are exposed to more techniques and kata with increasing complexity, and by the time you get about half way to black belt, you are also expected to be able teach basic classes. While we do train for kumite (both full-contact and point-sparring), the emphasis is always on being a karateka first, and then on being a fighter. Anyone can be a fighter. To be a better fighter, you need be able to do karate too.
