I have a self-sharpening stainless steel kitchen knife made in Czechoslovakia with waved edge. It never sharpened, but it still works just fine for everyday kitchen needs, except for peeling (I have a ceramic peeler for that), because of the waved edge. However, I have no idea where to buy a second one. «Bread knifes» with roughly similar edge are large, thick, and non-flexible.
