Semi-automatic tool for cutting pizzas into pieces of the same size

In a tool for cutting a pizza, wherein the pizza is substantially circular and has a center portion, wherein the tool cuts the pizza cleanly and evenly through the center portion thereof, wherein the tool includes a fixed member having respective sides and further includes a spring-loaded lever for manually pressing a circular plate downwardly thereof, the plate having a center axis and carrying a plurality of circumferentially-spaced cutting blades depending therefrom, the blades forming an angle therebetween, and wherein the pizza is supported on a cutting board below the plate, the improvement wherein the plate is rotatable about the center axis and is provided with at least a pair of upstanding pins straddling the fixed member and disposed equidistantly therefrom, the pins being further disposed radially of the center axis of the plate, each of the pins having a longitudinal center axis and a center-to-center distance between the respective axes of the pins being such that a maximum rotation of the plate is substantially one-half of an angle between two consecutive blades depending from the plate, whereby the plate may be rotated in a first direction and through an angle such that one of the pins abuts against a respective side of the fixed member on the tool, whereby the spring-loaded lever may be depressed to make a first cut into the pizza and then released, whereby the plate may then be rotated through an angle in the opposite direction such that the other pin abuts against the other respective side of the fixed member on the tool, and whereby the spring-loaded lever may again be depressed to make a second cut into the pizza, such that the pizza is cut into a number of pieces which is twice the numbers of blades.
