So I'm having trouble with my new Kato.
Upon receiving it, it got a nice natural patina forming, and then I put it away for a week or so and when I brought it back out, there was rust on it. So I polished it off as best I could, forced a new patina this time, and used it a couple times to help it 'set'. Then, same thing, a few days left lying down and it's got some rust streaks/spots developing. Did I just not sufficiently set the patina? The rust seems to be growing on top of the patina which seems odd and the knife is stored the same as all my other blades and those don't have any issues. Though this ordeal has made me realize that most of my knives have some bit of cladding or KU finish as I'm not used to dealing with this stuff, the 2nd most reactive knife I have after this one is Kono Fuji Blue 2 which is a fairly reactive knife but again, that one has no problems after setting a patina, and under the current method of storage.
This is the best shot I could get of the rusty streak because from most angles it just blends into the patina. It's the orange streak just up and left from my index finger.
This is one from a different angle where it doesn't even look like rust, but it's there, just to the right of that top section of blue patina, starting roughly at the latitude of the OralB mark there.
So, what should I do? I like pattern I got on this patina and would like to salvage that if possible, but will start again if need be.
And if that's what I should do, how do I keep this from happening again?
Any help would be greatly appreciated.
