Patina photos

A kitchen knife forum without a patina thread feels... empty.

Here's my Yoshiaki Fujiwara Sujihiki 270. It's kind of reactive.

I need some education. Looking at Jeff b photos of his life patina it looks almost orange in color. I thought that meant it is a sign of beginning rust.

I have been removing this from my stainless clad knifes.

Not sure any more what is ok patina and what is rust.

A general rule of thumb is to wipe a dry blade on a clean paper towel. If the towel is still white, there is no rust, if it transmits any color, its rust and should be removed.

Medium rare meat followed by hot water gives the bluest patina I reckon

Agree with this. I used to be a bit hesitant about some types of patina, but last summer I had a rust attack on several knives staying in a kitchen drawer and... now I know what real rust looks like.

My experience with patina is that it will shift in color depending on how the light falls upon it. From one angle it can look like faint & milky and from another angle you see the colors (blue, orange, brown, sometimes almost black). Rust however will look like an ugly piece of dry dirt from any angle. If you draw your fingers over it, you will feel it, since it has started to corrode the metal and is eating its way into the blade surface.

There is definitely a difference in some orange and yellow tint and rust. If you look at most of the knives in this thread there is some orange and/or yellow tint in the patina. When there is rust there you'll know it. The colors and patterns in my knife change each time I use it.

I am convinced that what had was patina and not rust. It came off easy with bar finders friend and gentle scrubbing. Also no pitting.

Only used twice so far, but it's starting to develop some nice blues after trimming some pork tenderloin last night.
