The blade (16a, 16b) has a first portion (20a, 20b) with a highly-sharpened leading edge for cutting the foodstuffs and at the end of which is provided a second portion (22a, 22b) with a non-sharpened leading edge for striking the foodstuffs so as to promote their bursting. ## Claims ### Claim 1 A rotor for cutting foodstuffs, intended for a food processor, comprising: a rotary drive hub, and at least one blade attached to the hub and extending radially from the latter, wherein the blade has a first portion with a sharpened leading edge for cutting the foodstuffs and a second portion located at the free end of the blade with a non-sharpened leading edge having a frontal surface that lies at least partially within a common plane of rotation with the sharpened leading edge for striking the foodstuffs so as to promote their bursting. ### Claim 2 (depends on 1) The rotor according to claim 1, wherein the leading edge of the first portion of the blade bulges in the direction of rotation of the rotor. ### Claim 3 (depends on 2) The rotor according to claim 2, wherein the leading edge of the second portion of the blade has a flat surface. ### Claim 4 (depends on 1) The rotor according to claim 1, wherein the frontal surface of the second portion of the blade comprises a surface that is substantially orthogonal to the direction of the velocity vector of the second portion when the rotor is rotating. ### Claim 5 (depends on 4) The rotor according to claim 4, wherein the frontal surface of the second portion of the blade is concave in the direction of rotation of the rotor. ### Claim 6 (depends on 1) The rotor according to claim 1, wherein the leading edge of the second portion of the blade has a flat surface. ### Claim 7 (depends on 1) The rotor according to claim 1, comprising at least two blades attached on either side of the axis of rotation of the rotor. ### Claim 8 (depends on 7) The rotor according to claim 7, wherein said at least two blades are attached and configured symmetrically on either side of the hub. ### Claim 9 (depends on 7) The rotor according to claim 7, wherein the hub is overmolded on corresponding inner ends of the blades. ### Claim 10 (depends on 1) A food processor comprising a food receptacle, and a rotor according to claim 1 rotatably mounted within said receptacle. ### Claim 11 (depends on 3) A food processor comprising a food receptacle, and a rotor according to claim 3 rotatably mounted within said receptacle. ### Claim 12 (depends on 11) The food processor according to claim 11, comprising at least two blades attached on either side of the axis of rotation of the rotor. ### Claim 13 (depends on 12) The food processor according to claim 12, wherein said at least two blades are attached and configured symmetrically on either side of the hub.
