It might be, it might be corrosion, if it's cheap, it might be worth the risk, but I would most likely pass. (I'm assuming this is an eBay purchase)
It was in with a roll I bought, I thought it might be corrosion too but it's way to straight and right next to the other 1.
Hmm, maybe pics hard to tell from. I got a butt load of steels in a roll at the end of last year. Never really looked at them, think you may have found me something else to do this 4 day weekend.
This one is so dirty, it just might be a mark/scratch, it does seem really straight though for a scratch or mark that small...../shrug
