Cladding lines

[friz]

Hi. Strange cladding lines I found on this knife. I can't feel them by touch but they are visible, and I have never seen these before. Thoughts?

You expected it to be a monosteel?

No, I have never seen that line before between core and clad. It is hard to get in the pictures.

It's carbon migration from the forging process. When using high heats as for the forgewelding some of this will happen. Superficial carbon content from the edge steel will move over into the iron.
It can be difficult to say if it's too much or bad just by pics, as it's width will depend on angle of the grinding. If the knife works well, don't worry about it.

Thank you.

did you talk about the cloud above the welding line or about the "weak" welding line ?

I see a lot of Katos with a black line like that at the juncture of cladding and core steels. And it can be felt with the fingernail in some instances.

that black line that follows the cladding but necessarily matches it.

Completely normal. Seen it many times.
