Another Japanese 'style' knife maker whose work is worth consideration is Steve Corkum. He does not normally make san mai (layered) blades, but uses simple carbon steels like 1050 and does a clay temper which produces a nice hamon. His wraps are Japanese 'style', but are not exactly traditional in the Marotzian nomenclature. But his knives are a good value, are super strong, and make great using knives. Check them out:

I am also a big fan of Don Fogg's work,
Don Fogg's web site. When you start to appreciate the enormous amount of time that goes into the making of a 'traditional' Japanese sword blade, they do not seem quite so ridiculously expensive anymore. As HJK points out, a traditional Japanese Knife is much harder to define than the features of Japanese swords (tanto, wakizashi, katana).
HJK, PLEASE come over to the sword forum from time to time. It does host some great discussions, but could use more folks interested in real knives and swords, as opposed to cheapo replicas. And Robert is right, he is usually to only defender of what is true Japanese 'style'.
