I got a BAD in the mail today and it's got a strange mark on both sides of the blade - almost like a flame was held against. I tried washing it thinking it might be a sap stain but it's still there ??

Any of you lads seen anything like this before or have any ideas what this may be ?
 
No way to tell without pics.

Was it used, or carried?
I've never seen one patina enough to notice it much. I've had one get just a tad darker, but unless it was beside a new one you wouldn't really notice.
 
haven't asked the previous owner. Will try get pics!

could be patina but I've never seen infi patina like this
 
No idea without pics.

I have yet to have anything patina my BAD yet. I have had some show up on a satin warden, but it came off with a light buff with the strop. Just a few passes. I tried to get my FBMLE to show some staining. I put it away dirty and sappy for a week, but it all came off with a good soap and water scrub.
 
The only rust on INFI i've ever had was on an NMFBM I used to chop up a watermelon. I left the juice on the blade for a day and it was spotted pretty bad.
 
Meat can give INFI a patina/stain. I've seen it with raw pork, and a cooked sausage.

Maybe someone got trigger happy with a belt sander and ruined the heat treat along the edge...?
 
Did you buy the knife used? I don't blame you for being concerned, that doesn't look good.

My guess from the pictures and not seeing it in person, it looks to have been overheated (heat discoloration). You can always make the secondary bevel shiny with a stone. I would be inclined to return the knife and not take any chances of the heat treat being effected. :(

Looks like a buff or grind overheat for sure. Hard to tell if the edge has been messed with though. The grind looks very even. Was the knife supposed to be new?
