I have only had my knives for a short time, but so far they are wonderful. I usually do not conform to the handwashing rule, as I am a have a background in nutrition/food science and prefer the food safety associated with using a dishwasher over longer lasting products. But I decided to go ahead and see how things would go with handwashing. So far no major rusting or becoming dull. I use daily, really more than, since I received just in time for holiday cooking. I am sad that the other items in the line have been discontinued.
