A pie cutter has a centrally disposed hinge and a plurality of cutting blades extending from the hinge. The blades are collapsible relative to one another so that the side walls of the blades are juxtaposed next to one another when the pie cutter is not in use. The blades may be expanded relative to one another to define a cylindrical configuration with the blades equally spaced angularly from one another to define cylindrical sectors. In a preferred embodiment, successive blades are joined at their outer peripheral ends by pivotable links which are collapsible when the pie cutter is not in use and which are expandable when the pie cutter is to be used. In another embodiment, a string extends in a loop through the outer peripheral ends of the blades and provides for a controlled movement of the blades between the collapsed and expanded relationships.
