As another person of the Chinese persuasion, I agree with what kidwholaughs has said. If you want to keep with tradition, get carbon steel with a wooden handle. I like the one pointed out by tonyccw. I grew up in Chinese restaurants and they all were like that one. Like Kid said, sharpening was not required very often and rusting, well they all had a nice patina. They were usually rinsed and wiped down. Like cast iron skillets, they kinda take care of themselves with natural oils. New ones can get rusty. You have to season them. You don't "wash" them.
My mother, at 90, still wields one with amazing precision. She will chop up a chicken with sufficent force and closeness to the other fingers, that many men would faint. But chopping is a side line. It is the Chef's knife as Kid says, primarily used for slicing and dicing.
The "cutting board" is the matching piece and important. Way back when, my dad used to get a slice of tree trunk about 14"- 16" in diameter, 3"-4" thick and bind it wtih some sort of material that I can't clearly remember. He would sand it smooth and that was his cutting board. He wanted something heavy to withstand chopping. I know, all sorts of sanitation questions come up, but that's what I grew up with. He'd rinse it off with water and that was that.
BTW, a secret to getting those really thin slices with the Chinese knife and provide more safety than is apparent, is to use the knuckes of the support hand to guide the side of the blade. In other words, the hand holding the food doesn't have the fingertips closest to the blade. The fingertips actually curl under slightly, causing the knuckle to come in contact with the side of the blade significantly above the cutting edge. This acts as a guide to thickness of cut. This is also why you want a tall blade. Never understood those short Japanese blades.
I hope no one has minded my trip down memory lane. And as I write this, I suddenly realize I presently don't have a Chinese knife in the house.
I hang my head in shame. What would my ancestors think.
