The Chain Fighting Course is designed to enable you to use a common hardware store chain to defend yourself effectively against multiple or single assailants, armed or unarmed.
"The Course is designed for a person who is not a martial artist. The time required to master the system presented in the course for most people would be 3-5 hours which can be spread out over several days or weeks. Once mastered the system requires about 5-10 minutes of practice weekly. You do not need to be in any great physical shape to master the chain fighting system. A wheel chair bound person could become effective with the system."
