I ruined my para :(

Rmc85 the patina in your knife is soo light it's almost undetectable! Does it still help with corision being that it hasn't fully formed ?

I agree with you. I would be shocked if your polishing media interacted to cause the issues with the blade.

I remain very puzzled by what happened. As far as I can figure, a CPM blade should not do what yours did. I'd send it to Spyderco if only to get their take on what happened.

I confess that I don't understand the homebrew "patina" thing. If I wanted to protect my blade, I'd try something like one of the shake 'n' bake coatings or a surface blackening treatment meant for stainless. No biggie, though. They ain't my knives so it's basically none of my concern.

I wonder if that is the case. I used blue magic polishing cream lightly between the patinas. the knife was cleaned scrubbed and degreased with simple green prior to the patina.

And yeah, I would never expect spyderco, or any manufacturer to cover any of the repairs at their expense. I did what I did and will cover the costs of repairs/replacement myself.

I don't think I will experiment with forcing patinas again. my opinel has a great natural patina, but that is because it is carbon steel. cpm d2, while it will take one eventually, is stainless enough to not need one (at least for me, my blades are always clean).

This knife never had any problems before I started messing with it. I live in San Antonio where the air is humid and always kept the para in my right rear pocket, and never had any problems with rust or staining. I usually take good care of what I have, and the knife was always well maintained.
