Abstract:
A cutting device is provided for opening the container of a standard oil filter and comprises a rigid mounting frame; first and second support disks rotatably mounted to the mounting frame, the first support disk including an outer edge which is roughened so as to frictionally grip the oil filter; a handle for rotating the first support disk; and an adjustable, rotating cutting blade, the cutting blade made adjustable by an advancing mechanism such as a screw. The first and second disks and cutting blade are disposed relative to each other so as to support the oil filter when the adjustable cutting blade is properly positioned. The oil filter is then rotated by the handle such that the cutting blade effectively separates the top and bottom portions of the oil filter.
