The handle is configured for grasping by a user. The cutting member support extends from the handle. The first disk member is supported on the cutting member support. The second disk member is supported on the cutting member support. The first and second disk members may be arranged non-parallel relative to each other. ## Claims ### Claim 1 A cutting device, comprising: a handle portion; a support member extending from the handle portion; first and second cutting members mounted to the support member, the first cutting member defining a first cutting surface and the second cutting member defining a second cutting surface, a first portion of the first cutting surface being arranged adjacent to a first portion of the second cutting surface so that the first portions of the first and second cutting surfaces effectively act as a single point of cutting, and a second portion of the first cutting surface being arranged spaced apart from a second portion of the second cutting surface; wherein at least one of the first and second cutting members is arranged at a first non-perpendicular angle relative to a first plane in a first direction, and at a second non-perpendicular angle relative to the first plane in a second direction, the first and second directions being perpendicular to each other. ### Claim 2 (depends on 1) The cutting device of claim 1, wherein the first and second cutting members are disk shaped members, wherein outer periphery edges of the first and second cutting members define the first and second cutting surfaces. ### Claim 3 (depends on 2) The cutting device of claim 2, wherein the first and second cutting members are arranged non-parallel relative to each other. ### Claim 4 (depends on 1) The cutting device of claim 1, wherein the support member defines first and second mounting surfaces that support the first and second cutting members, respectively, wherein the first and second mounting surfaces are arranged non-parallel relative to each other. ### Claim 5 A cutting device, comprising: a first disk shaped cutting member defining a first cutting surface around a periphery thereof; a second disk shaped cutting member defining a second cutting surface around a periphery thereof; wherein the first and second disk shaped cutting members are arranged at a compound angle relative to each other with a first portion of the first cutting surface being positioned adjacent to a first portion of the second cutting surface, and a second portion of the first cutting surface being positioned spaced apart from a second portion of the second cutting surface, the first portions of the first and second cutting surfaces effectively acting as a single point of cutting. ### Claim 6 (depends on 5) The cutting device of claim 5, wherein the compound angle include a first angle relative to a first plane and a second angle relative to a second plane, wherein the first and second planes are arranged perpendicular to each other. ### Claim 7 (depends on 5) The cutting device of claim 5, wherein a first portion of the first cutting surface is arranged adjacent to a first portion of the second cutting surface, and a second portion of the first cutting surface is arranged spaced apart from a second portion of the second cutting surface. ### Claim 8 (depends on 5) The cutting device of claim 5, further comprising a handle and a support member extending from the handle, wherein the first and second disk shaped cutting members are mounted to the support member. ### Claim 9 (depends on 8) The cutting device of claim 8, wherein the support member includes first and second mounting surfaces configured to support the first and second disk shaped cutting members, respectively, wherein at least one of the first and second mounting surfaces defines the compound angle. ### Claim 10 (depends on 9) The cutting device of claim 9, further comprising first and second axle portions about which the first and second disk shaped cutting members rotate, respectively, wherein the first and second axle portions extend perpendicularly from the first and second mounting surfaces, respectively. ### Claim 11 (depends on 5) The cutting device of claim 5, further comprising first and second axles about which the first and second disk shaped cutting members rotate, wherein the first and second axles are arranged at the compound angle relative to each other. ### Claim 12 A pizza cutter, comprising: a handle configured for grasping by a user; a cutting member support extending from the handle; a first disk member supported on the cutting member support; a second disk member supported on the cutting member support; wherein the first and second disk members are arranged non-parallel relative to each other, and the first and second disk members are arranged at a first angle relative to a first plane in a first direction, and a second angle relative to the first plane in a second direction, the first and second directions being arranged perpendicular to each other; wherein the first and second disk members converge together to form a single cut through a pizza. ### Claim 13 (depends on 12) The pizza cutter of claim 12, wherein the cutting member support includes first and second axle members about which the first and second disk members rotate, respectively. ### Claim 14 (depends on 12) The pizza cutter of claim 12, further comprising a scraping member, the scraping member arranged to contact a side surface of at least one of the first and second disk members.
