January 25, 2015

This week we have the 2nd part of my interview with Sensei David Hamann. Mr. Hamann started training in karate in 1973 with Phillip Koeppel and is currently a 7th Degree Black Belt in Shuri Ryu.  He is also the head instructor and co-owner of the Kosho School of Karate in Cincinnati Ohio. We went through Sensei Hamann's bio at the opening of last week's show, so please go back and have a listen if you haven't checked it out yet.

This week we get into Mr. Hamann's college years at the University of Cincinnati, his first meeting with Shuri Ryu Chief Instructor Mike Awad,and finding a way to train during his intern ships.  We also discuss the industrial design business and some of the products he has designed and are on the market, including the Snack Nanny, Whamo's Frisbee Toss-X, Rubbermaid's Action Packer,  Century Martial Arts' Flex Master, and the Microbar, just to name a few.
