Not sure if durability and low maintenance are endangered by a blade being Japanese, or assured if European. The best European santoku I know is the carbon monosteel Lignum 3 by Robert Herder. 1.2519 @60Rc, and nail-flexing. The surface polish reduces reactivity a lot. But I don't think that's what you're looking for. Could you develop a bit what durability and low maintenance means to you? Is it about being built like a tank, or having an edge that offers great edge retention, or resistance to chipping, or rust resistance? All these properties hardly can be combined. Most typical European knives are made of soft stainless, and being tough is the only positive thing I can say about it. Edge retention is mediocre, performance is poor, sharpening them is no fun at all and they don't take or hold good edges.
