I have a knife with carbon blade that started discoloring immediately (I used it to slice an apple and immediately rinsed and dried it off). I believe I read somewhere that it can be desirable for some carbon blades to have a bit of discoloration, as it may act as a slight protectant of the steel.
Is this true? By the way, the blade in question has a mirror-type finish, not a satin finish, and the discoloration definitely is not rust.
Thanks.
Jim
