A kitchen knife comprises a knife face heave, a knife handle and a knife face, wherein the lower middle of the knife face is transversely provided with the knife face heave; and the lower middle of the knife face is provided with a slight transverse heave. When vegetables stuck on the knife face touch the heave part, the vegetables are obstructed to naturally drop onto a chopping board. The kitchen knife has the benefits of effectively avoiding the sticking problem between vegetables and the knife face during chopping process and leading to a more smooth and orderly chopping process.
