I like Tegner. Unlike the comments of a previous reviewer i find Tegner is grounded in reality. He gives you the facts about movies/TV and how what is shown is vastly different than real life. He explains how to do things in a practical way, and how a lifetime of study is not required. Tegner was a pioneer, long before Bruce Lee asked people to question tradition, Tegner was already giving the answers. The introduction in his book "Complete Book of Self-Defense" is pure gold. It contains solid information that puts self-defense into it's proper perspective.
