Hen na Hamon no kizu?

[tokashikibob]

Gentlemen,

Have not gone to see this one yet, but the picture(s) show weird spots on the hamon, shingane? Looks to be recently polished. Does the mei look legit?

 

Best Regards,

Bob

They look like where pinholes were made by corrosion and too deep to polish out without major major loss of steel. John

Thank you John, that makes sense. Not a fatal flaw I would think, but not good news. I'll have to see what it looks like in hand.

Best regards,

I agree with John, but am having trouble figuring out why the corrosion would just be in the hamon, which is much harder, rather than the ji....

Ken, it may just look like that, we are only seeing a portion of the sword. There may be some spots towards the shinogi. The corrosion may have been localised in the saya or it may even be an original forging flaw. It needs assesment in hand for sure. John

Ken,

 

the HAGANE contains more carbon and thus is more easily attacked by acids and corrosion than the 'softer' JIGANE.
