ABSTRACT:
An apparatus for rendering ovals of adjustable sizes and ellipticity upon various materials. An oval cutter comprises a clickerplate for adjusting the ellipticity of ovals in a single movement. The clickerplate can be rotated about a base using a knob mounted on the clickerplate. One embodiment of this invention comprises a storage compartment in the knob which can hold, for example, extra blades. A further embodiment of this invention comprises an arm that translates through the clickerplate and a swivel plate used for setting the overall size of the oval by locking the arm at a set length. In yet a further embodiment of this invention, ovals can be rendered in either a clockwise or a counterclockwise direction and an arrow can indicate the direction in which the apparatus is set to render ovals.
