Once again on the topic of curing a blade. I have heard about cutting a catus leaf and placing it in a fire. Letting the leaf begin to pop and sizzle on the fire. Once the leaf began to pop and sizzle on the fire, remove it. Once the leaf was removed a blade was to be placed inside. This was to "cure" the blade. I haven't tried it yet. But since we're on the subject of "Patina" . I would like to know if there is a better way of doing this. Suggestions please.
