Never use a dishwasher. Don't cut on ceramic or glass or stone. Use the right blade for the right task. HOne the blade every so often. I have had my knives for 6 years, used very very heavily, and they are as sharp as the day I brought them home.
I have both German and Japanese knives. Of course they need sharpening, although the honing steel will tend to extend the time between sharpening.
