Are these low spots?

[AT5760]

I ran across these while doing some window shopping (cropped so as not to identify maker/retailer). Are these dark spots low spots? Hammer marks? Something else? Any impact on performance?

Yes, they look like hammer marks left over. Not a big deal as long as they're not along the edge, more of an aesthetic preference thing if anything.

I'd say they're hammer marks. I doubt they'd affect performance, since they're significantly closer to the spine.

Thanks. That answers the question.

Maybe its just camera angles/lighting, but dang that's a heavy scratch pattern.

looks like a carter, probably a muteki. If so they are hammer marks and they all look like that.
