We assume you're talking about the damage on and to the left of the digit "1"? it's not an error. It's been hit hard by something hard, sharp and pointy, like a chisel or screwdriver. The sharp point has gouged out some of the metal, and the resulting pile of gouged-out metal is sitting over to the left of the gouge.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
