What a wonderful experience for me to meet (albeit virtually) Mr. McKinnon. We all enjoyed the entire experience and you will too. I'm adding a few notes so you won't be tempted to stop and search mid interview. Here ya go:  At minute 13 he mentions the Japanese word kihon which simply means basics.  He talks about a kata called Gojushiho and after you listen it's an easy find online and worth a peek! In one of his stories he mentions soto uke -which is simply an outside block. And finally he discusses iaido kata and those are sword forms. Happy listening!
