A knife has a generally flat blade with a sharp curved lower cutting edge which terminates forwardly and rearwardly in sharp cutting ends; an upper surface of the blade opposite the cutting edge is extended upwardly and forms a stem, and a curved cross section outwardly pointed handle is connected to the stem so that maximum cutting force occurs on portions of the cutting edge nearest the rearward end of the blade. A food chopper is constructed with an upward and forward curving handle and a distal forward pointed end and a rearward proximal curved sharp end on the blade and with decreasing radii of curvature toward the rearward proximal end. A cutting knife is formed with a cutting edge of uniform radius of curvature terminating forwardly and rearwardly in distal and proximal pointed ends, with a central portion of an upper surface of the blade curving upward and rearwardly and integrally forming a stem. A rounded handle with a pointed end extends rearward from the stem in a direction generally parallel to a tangential direction of a center portion of the cutting edge.
A knife comprising a blade having a convex curved lower elongated cutting edge terminating forwardly and rearwardly respectively in a forward sharp end and a rearward sharp end and having at least one of the ends pointed, the blade having an upper surface opposite the cutting edges between the forward and rearward ends, and a continuously uniformly curving stem extending upwardly from an upper surface of the blade at a position from the forward to the rearward ends, a handle connected to the stem, and continuously uniformly curving with the stem and extending outward therefrom away from the blade and wherein the handle has an elongated upper convex curve opposite to the convex curve of the cutting edge of the blade in a plane of the blade.
