Patina question

Pendexter said:
It's called stainless, not stain never ;) Maybe my nomenclature is off in the knife world, but I thought the oxide layer developed during the acid etching possess was considered a "patina".

OP asked about the esse6 specifically, but also a general question on consistent darkening of a blade.. The more stainless the blade, the stronger the acid required to patina.

I don't know of anyone trying to purposely put a patina on stainless but I'm sure that someone has.
Just can't understand the reasoning behind trying to put corrosion on a metal that is designed to resist corrosion but to each his own.

One reason/excuse is that an acid stonewash hides scratches. But I think it's mostly for looks. I like tinkering as much as I like using my knives.

But as you say, to each his own.

Hey OP, sorry for derailing your thread talking about stainless. Here's a photo of some high carbon blades :)

Ultimately, the more you use your knives, the more consistant the patina and the darker it gets. If you want it lighter, use a metal polish.

Even if you get a perfectly consistant patina on your new knife, it's just going to get splotchy once you start using it.

No worries on derailing. It is a general patina question as I do have stainless as well. I have an opinel carbone 4 inch paring knife that won't take a decent patina.
I think the patina for people is a corrosion but also personalizing.
P Pendexter that's is a nice 562
 
There are plenty of acid wash stainless blades out there which is nothing more than a patina finish. I have a couple AEB-L customs that way and I believe Bradford knives has an acid wash finish for the M390 blades. Tops also has their acid rain finish which is a patina. I think it's more commonly done on the smaller batch size types of blades as I have to imagine coatings are easier on a mass scale approach.
 
I have been doing research and it seems that using a straight acid can also clean your knife and not give it a patina when stainless. It's called pickling in an acid bath I think something like 14 percent muriatic.
I have seen acid washing. I feel as those ones from manufactures on stainless are like a stonewash. It's more to hide scratches from use or machining marks but give the blade darkness. I do like the darkness it gives. I'd want a acid wash but a even darkness. It doesn't have to be super dark can be grey but even.
