Interesting "Artifact" from Rolling

[tkroenlein]

I etched and stonewashed this blade today. When I got it out of the tumbler, I noticed this interesting(?) stripes all the way through the steel. I cut this out at about 15Deg to the length of sheet, so I'm assuming this is some type of something leftover from rolling. This is "European" 80CrV2.

I've pretty much never etched a piece of steel that didn't reveal something I didn't expect. I didn't notice this after etching, just after the tumble.

Almost certainly something from the manufacturing process. Looks pretty cool, though!

I hear impurities rear up every once in a while but it could be something else.
