Oxidation on S30V

Ignoring your stainless bead blasted blade for a few weeks shouldn't result in it being coated with rust. I've not experienced this. I've even got a high carbon bead blasted blade that's been sitting unattended for years on top of my dresser with no problems. I have had problems if I leave a blade in contact with the wrong material - bead blasted or not.

Perhaps the beadblasted blade needs a good passivation?

I went to 2 gun shops, 2 sport shops, 2 grocery stores and a hardware shop in my town and could not find one single product that was recommended by you guys. Welcome to small town New Zealand. :barf:

You can find the Flitz on Ebay. I don't use brasso anymore on knives, it cleans em up, but if you put em away and check em after a couple of weeks, the stuff turns green, especially brass bolsters, like on a Buck 110. The Fritz doesn't do that. The Fritz can also be used on fiberglass and plastics. It made my trucks' hood/bug protector look like new- lexan/polycarbonite whatever it's made of.

Beadblast will give a smooth matte finish that is quite rust resistant.
Sandblast is a problem because it creates a rougher and much more porous
finish.
Some use these terms interchangeably, but they are quite different process' with very different results.

Something that hasnt been mentioned and may or may not make a difference is that CR uses a ceramic media to stonewash their blades. I also have not had a beadblast blade corrode. Buck uses glass beads.Dont know if that matters either. Cliff, could you shed some light on that? guy

Different enviroments, a greater humidity, far greater temperature, or closer to a marine enviroment could all greatly accelerate corrosion. I carry lots of blades that don't rust without oil but I live in a fairly tame enviroment in that regard.

While I cannot give details, I understand that not all beadblasting is created equally. IIRC (it's been a while) a good bead blast uses intact beads that harden the surface and actually prevent rusting, while a bead blast with broken beads will create this microcracks and pores and allow rust to occur. I'm really not a expert on this. Perhaps someone will chime in and give a better answer.

I have indeed had the same green experience on some other knives - especially on the brasses. The knife in question has no brass bits visible, so no problem if they turn green. Ebay is indeed an option, but the freight of such a small item is a killer to NZ.
