They remind me of a guy I took knife fighting lessons from.
"My word is good on this technique because of my strange and violent life where I used the technique which, by the way, is trained in militaries all over the world, who learned it from my teacher and my teachers teacher who I am the only living grand master certified under all 8 of their systems and both the blended family systems which I learned though dangerous live blade methods but my wisdom and thorough examinations of the techniques have allowed me to condense and refine their teachings into a safe system that can be practiced by anyone in any physical condition, because the true art is not the art of killing, but the art of overcoming fear and bettering yourself, in the way that I have."
