There are the most different opinions about the "ninja master" Ashida Kim aka Christopher Hunter or Radford William Davis. As many others, he was one of those who knew how to magnificently make self-marketing during the ninja boom in the 1980s.
His book "Secrets of the Ninja" was one of his first books. Meanwhile, the title has been published as softcover version announced as follows: Back in print! Bigger and badder than ever!

A book for real assemblers.
