I bought this steak knife set because it was listed as dishwasher safe. I've had them about 3 weeks and they've gone through the dishwasher several times. There is some discoloration but not too bad. I love that the handle and blade are one piece. The only issue is that my kids sometimes mix them up with butter knives. The only real difference is the steak knives are much heavier than butter knives. They cut well, but the serrations are small.
