Abstract
A paper processing tool includes a base having a receiving area for selectively receiving a sheet of paper. The tool further includes a first lever having a handle portion, the first lever being pivotable relative to the base about a first axis. An intermediate lever is pivotable relative to the base about a second axis in response to movement of the first lever. At least one cutting element is arranged along a cutting plane, the at least one cutting element being configured to selectively engage the sheet of paper. A drive lever is actuable by the intermediate lever to move the at least one cutting element relative to the base. The drive lever is pivotable relative to the base about a third axis parallel to the cutting plane.
