I guess I just got lucky..
I found Hock on one of those old AOL FMA boards in the 90's about the time the Congress of American Knife fighters started up. I had just moved to Texas from California, and decided I needed some more knife skill in my game. I had a working knowledge of the blade, but knew I needed more.
I contacted him and he referred me to one of his students who was teaching in Kerrville Tx which was a little closer to me than Dallas...
"Who was this long haired little killer"? To be revealed later in the post...

That 1st day on the lawn of the national guard armory in Kerrville was my intro to Hock's material, and I have never looked back.
I play with other material to help flesh out my game, but for the most part I just train the level 1 - 10 knife material.
I still work the knife material he has shared over the years in our evolution from Presas style Arnis to Combat Arnis to Filipino Combatives to the PAC.. Some really good stuff in there, and I can't let it go.
The last time Hock was down I showed him those old rank reference sheets we had back when he was teaching Arnis prior to Combat arnis. ( Pre- manual days ).... Good stuff... The panananstas drills, the lethal and non-lethal scenarios... The 6 reverse grip slash and stab drills that turned into the "Alley Cat" drills....
Unless you want to become a blade ballerina, you don't have to go any further than the 10 level knife course. But the beauty of it all is... Hock doesn't mind if you go play around in other playgrounds.. He shows you the material, but doesn't bind you to it. He let's it be the skeleton, and allows you to flesh out your training.
Go find some good stuff, and share it with him next time you see him.. If it is good he will tell you, and if it sucks he will tell you too....
He has probably the best B.S. filter in regards to martial arts material out there. And he is willing to let you know what he thinks. So just ask him..

What began as a search for knife material led to training in all areas of the SFC.... Hock is a major influence on how I train and teach today.
So that's it for my little plug. Big thanks to Hock, my blood brother Dan Lewis, and all the other Dallas guys... Professor, Arnold, Rawhide, Red 5, for giving us a place to call home.
