Read & scroll. The article is a few years old, but spot-on. Joe is one of the more well-respected members of the BladeForums Mod/Admin. team. And, he also has an account on CPF. A decent and knowledgeable fellow.
As for my take on O-1, I will admit to liking the better stainless steels than any type of carbon steel. A thin coating of oil on an O-1, when not in use, is always a good idea. Otherwise, it might rust away as you're looking at it.
As Joe mentioned in the article, legendary Randall Made knives uses O-1 for their carbon blades. Their stainless blades are 440-B. (American twin sister of AUS-8; from Japan. AUS-8 is horribly underrated. Then again, so is 440-C.... A blade steel that will easily keep up with many of the newer, exotic steels on the market. Even heard some knifemakers say that they'd still be using 440-C, if it wasn't for the fact that their paying customers insist on the use of "modern" exotics).
Here's another link that contains a by-the-numbers breakdown of what to expect....
