Hi Moshah and thanks for showing it!
It might be the pictures or it might certainly be me - I
am super-paranoid about these things - but doesn't the condition of the blade kind of look a bit like an acid dip? I.e. that the blade perhaps has been artificially aged?
I could be completely wrong here and for sure wish it so - I am no specialist - like I said, just paranoid.
Anyway Moshah, I hope it cleans up nicely and hope to see more pics.
Best wishes, - Thor
