So you are saying that:I am sorry to say with me it you like boxes and papers you will have to get over it. A nice little compact padded case that I don't mind keeping around will likely go a long way towards insuring the knife wont have scratches or be loaded with crusty dust bunnies. You can always wash the case if the outside has crusty dust bunnies. Try that with cardboard.
1. Without the pouch, your knives get loaded with crusty dust bunnies
2. A cardboard box wont protect your knife from the crusty dust bunnies?
