Abstract
Abstract In a cutting device and, in particular, a device for cutting a flat object, such as a pizza, or the like, a base is provided which has two oppositely facing flat surfaces thereon. Each of the flat surfaces has scribed therein a plurality of straight slots which intersect to subdivide the surface into a plurality of segments. The segments may be pie-shaped, square, rectangular, or the like. A cutting instrument is drawn through each slot on one of said surfaces to cut a superimposed flat object, such as a pizza, into pieces.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
177 words
In a pizza cutting device comprising a base having a pair of oppositely facing flat surfaces and a plurality of slots formed in each one of said flat surfaces, said slots formed in one of said surfaces pass through a common point located substantially at the midportion of said one surface and some of said slots in the other of said surfaces lie parallel to each other and the remaining slots in said other of said surfaces lie parallel to each other and are perpendicular to and intersect the first-named some of said slots, and hand-drawn cutting means having a cutting edge for cutting said pizza in the pattern established by said slots by drawing said cutting means across said base such that a pizza resting on said surface can be cut by the cutting edge of the cutting means, and said slots in both surfaces are of a width and a depth to coact with said cutting edge of the cutting means to produce a clean and complete cut through the pizza resting on said base.
Claim 2
Dependent Claim
177 words
In a pizza cutting device comprising a base having a pair of oppositely facing flat surfaces and a plurality of slots formed in each one of said flat surfaces, said slots formed in one of said surfaces pass through a common point located substantially at the midportion of said one surface and some of said slots in the other of said surfaces lie parallel to each other and the remaining slots in said other of said surfaces lie parallel to each other and are perpendicular to and intersect the first-named some of said slots, and hand-drawn cutting means having a cutting edge for cutting said pizza in the pattern established by said slots by drawing said cutting means across said base such that a pizza resting on said surface can be cut by the cutting edge of the cutting means, and said slots in both surfaces are of a width and a depth to coact with said cutting edge of the cutting means to produce a clean and complete cut through the pizza resting on said base.
Claim 3
Dependent Claim
188 words
In a pizza cutting device comprising a base having a pair of oppositely facing flat surfaces thereon, one of said surfaces having two sets of slots, one set of said slots being parallel to each other and are equally spaced apart and the other set of said slots in said one surface lie parallel to each other, are equally spaced apart and are perpendicular to and intersect the first-named set of said slots, the other of said surfaces has slots intersecting at a midpoint so as to divide said other surface into a plurality of pie-shaped segments, and a cutting instrument having a roller and a handle, said roller having a cutting edge inserted in one slot at a time and being guided by said slot as said instrument is drawn across said base, such that a pizza resting on said surface can be cut by the cutting edge of the roller, and said slots in both surfaces are of a width and a depth to coact with said cutting edge of the roller to produce a clean and complete cut through the pizza resting on said base.
