A circular material cutter having a disk-shaped base with a rotating top member attached thereto via a spring and shaft assembly. The top member has a handle formed on its top surface and four legs which extend downwardly from the top surface radial edge, and which have cutting wheels rotatably mounted on their bottom ends of the legs. The shaft and spring assembly extends upwardly from the radial center of the base and is held in a spring receiving portion which extends downward from the radial center of the top member. The shaft and spring assembly allows the top member to be rotated above the base, and also biases the top member away from the base when the device is not in use, to keep the cutting wheels in a retracted position. To use the device, one places the device on sheet material to be cut, pushes down on the top member, and twists it 90~ using the handle, thereby causing the four cutting wheels to cut a circular piece from a sheet of material. An adjustable embodiment permitting selected circles of different radii to be cut is also described.
