I had the same question and after making several calls, I think I have it.

The current manufacturer of the Ginsu knives is Douglas Quick Cut. They will replace your authentic Ginsu knives free of charge. I was told to send mine to them with payment of $2 per knife for shipping and a new one would be sent out. They only charge $1 shipping for the dinner knives.

But, they must be authentic. There was another company making fake Ginsu knives and they won't replace those knives. I was told that the fake knives are marked: "Ginsu 2000" or "Ginsu World Class" or "TV Knife."

Mail your knives to:

Douglas Quick Cut
