Abstract: A ceramic cutting knife comprise a handle part and a ceramic blade part fixed to the handle part. The blade part has a cutting edge; a back edge, the back of which is the cutting edge; and an arcuate tip edge formed at a tip portion of the blade part and being continuous with the cutting edge and having a predetermined radius of curvature. At least one side surface of the blade part comprise a large blade surface tilted from the large blade surface to the cutting edge, and a small blade surface tilted from the large blade surface to the cutting edge at a larger angle than the large blade surface. The small blade surface extends at least from the cutting edge through the arcuate tip edge to a location at which an arc of the arcuate tip edge terminates. This enables to suppress the occurrence of broken blades at the cutting edge and the arcuate tip edge.
