Welcome to Forgotten Sword

We are researchers and practitioners of historically accurate Chinese warrior arts. Since 1987, we have pioneered modern, multi-disciplinary, multi-cultural research, of Chinese warrior arts and their relevant offshoots. At the core of our endeavour is the research and practice of Yin Fa 隱法, the Chinese art of stealth and the origin of the Japanese Ninja 忍者.

We have authored the only book to ever be written – in any language – on the Chinese art of stealth. The first edition was a collector's item and the second edition will be available to the public in the near future.
