Abstract

A food grater having an improved cutting surface with teeth that are configured to prevent or reduce the sideways pull against a food item as it travels along the cutting surface. In a preferred version, the blades are formed with a V-shape that improves the ability of the user to push a food item straight down the cutting surface.

Claims (24)

1. A grater, comprising:

a cutting surface having a proximal end and a distal end;

a plurality of blades formed on the cutting surface, the plurality of blades defining a plurality of rows, the plurality of rows being positioned between the proximal end and the distal end;

at least a portion of the plurality of blades each having an upper edge and a lower edge defining an opening, the upper edge being relatively closer to the proximal end and the lower edge being relatively closer to the distal end, the lower edge further extending outward from the cutting surface to define a tooth, the lower edge forming a V-shape defined by a first upright, a second upright, and an apex positioned at an intersection of the first upright and the second upright, each of the first upright and the second upright extending angularly and upwardly from the apex in a direction from the distal end toward the proximal end, each of the first upright and the second upright further being substantially linear; and

the portion of the plurality of blades each further comprising a first side edge extending between the upper edge and the lower edge, and an opposing second side edge extending between the upper edge and the lower edge.

2. The grater of claim 1 , wherein each of the first side edge and the second side edge is substantially linear.

3. A grater, comprising:

a cutting surface having a proximal end and a distal end;

a plurality of blades formed on the cutting surface, the plurality of blades defining a plurality of rows, the plurality of rows being positioned between the proximal end and the distal end;

at least a portion of the plurality of blades each having an upper edge and a lower edge defining an opening, the upper edge being relatively closer to the proximal end and the lower edge being relatively closer to the distal end, the lower edge further extending outward from the cutting surface to define a tooth, the lower edge forming a V-shape defined by a first upright, a second upright, and an apex positioned at an intersection of the first upright and the second upright, each of the first upright and the second upright extending angularly and upwardly from the apex in a direction from the distal end toward the proximal end, each of the first upright and the second upright further being substantially linear; and

the lower edge further comprising a first edge, a second edge, and a central edge positioned between the first edge and the second edge, the central edge being substantially parallel to the cutting surface.

4. The grater of claim 3 , wherein the cutting surface is substantially planar and the first edge is linear along a line that is parallel to the plane of the cutting surface.

5. The grater of claim 3 , wherein the cutting surface forms a first arc and the first edge forms a second arc that is substantially parallel to the first arc.

6. The grater of claim 3 , wherein each of the plurality of blades is substantially identical.

7. The grater of claim 6 , further comprising a handle extending away from the proximal end of the cutting surface.

8. The grater of claim 3 , further comprising:

one or more additional cutting surfaces attached to the cutting surface to form an interior space; and

a handle secured to the proximal end of the cutting surface and the one or more additional cutting surfaces.

9. The grater of claim 8 , wherein the cutting surface and the one or more additional cutting surfaces define a base, the cutting surface and the one or more additional cutting surfaces being inclined upwardly and inwardly from the base toward the handle.

10. The grater of claim 3 , wherein the cutting surface is produced by the method of:

forming the plurality of openings in a metal blank; and

stamping the metal blanks to form the plurality of teeth.

11. The grater of claim 10 , wherein the step of forming the plurality of openings comprises etching the metal blank.

12. The grater of claim 10 , wherein the step of forming the plurality of openings comprises stamping the metal blank.
