I have saved many pictures of the roll from season 1 to keep with it and can verify you are correct about the Mundial knives. Believe it or not though, I do plan on using the roll and knives when entertaining. I have a background in cooking and do travel with my knives often. So I plan on filling it with all Global knives. I apologize in advance as I'm sure many here will cringe, its not 100% authentic. It is very similar and more useful for my situation though. Currently my roll and knife set is mixed of all different brand knives I've grown attached to over the years and I just couldn't do that to the Dexter roll.
Oh also, I'll likely be keeping a Michael C. Hall autographed knife in the kit as well that I received as a gift.
