Weird Question. Odd Blue Stain?

[Hastur]

Hi guys I have this odd blue stain on the tip of a showato.. really hard to see but it's a circular stain near the tip but not on the edge. After oiling the sword I can't find it anymore but I am perplexed at what it might be? It was on both sides but not the same shape.

Old oil?

[Hastur]

Does it make blueish colors, maybe gasoline was used? Don't think a dremel would make a circular burn mark hopefully.

[Bruce Pennington]

How peculiar?! You can no longer see it after oiling? I wonder if it comes back if you dry the oil off and let it set for a while?

[Hastur]

ya after oiling I cannot see it anymore... must have seen some weird cleaner at some point...

[Stephen]

probably clove oil

[PNSSHOGUN]

Or some madman with liquid bluing?

[Hastur]

I hope not. If someone did try to grind in that area would it make such a stain and ruin the temper? what does a temper ruining heat form grinding usually look like?

Brad,

it is the bad AO no KAMI. You can chase him away with oil, but you have to oil the blade regularly to keep him away. Don't use too much oil, a very thin layer will be sufficient!

A prayer and some blessed oil eh? I hope its okay with western stuff XD

Hello Brad,

Maybe some strange anomaly ! It doesn't look like the excessive heat type blue hue after someone's been at it with a grinder or polisher....That type doesn't go away with oil....not the ones I've seen anyway...!

Regards,

Paul.
