It is best to wash the knives by hand, since this hardened steel is prone to rust and since the dishwasher is counterproductive. I give sharp knives never in the dishwasher, because they then become dull when they strike other metal objects in the dishwasher.
Value for money is top. These knives can I recommend.
Addendum on 11.1.15: I just cut Speck Alto Adige at a time, she divorced the bacon excellent. Really thin strips. That can not be the most knife. And the tomatoes are cut without crushing.
