I've had good luck with an ATS-34 blade (stainless) sgian, though I prefer carbon steel (5160 or 1084).

Here's a description of ATS-34 that Google yielded:

"ATS-34 is a Hitachi product that is very, very similar to 154CM. Normally hardened to around 59-61 Rc, it holds an edge very well and is tough enough even at that high hardness. Many custom makers and production companies use ATS-34."

Not sure if you'd be able to find a pre-made blade in ATS-34 though...
