Morimoto I'm pretty sure is actually a Nenox rep. Not that that is a bad thing at all. I've seen a Carter on there before (not sure which battle). In the first battle that Garces had his opponent was using Suisin western handled knives. I've been trying to figure out what knife David Kinch was using (the guy from the battle cabbage referenced in the first post). It was a wa handled gyuto, but had a longer, flowing neck than any I could find online with no machi. Looked like a custom, very nice knife. Kinch's food has a lot of Japanese influence, so he probably got it in Japan from someone I can't find online.
Batali's sous, Ladner, used a deba and yanagi for a lot of Batali's later fish episodes, but I could never tell what the make was, and he didn't use them with traditional japanese technique, more like french technique with japanese knives.
Morimoto and his sous always blow my mind with how precise they are even in the time limits. Katsuramuki is hard enough as it is, but doing it all with yanagis in a big rush and hitting it just perfect makes me a little sick inside.
