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.

A paper processing tool comprising:
- a base having a receiving area for selectively receiving a sheet of paper;
- a first lever having a handle portion, the first lever being pivotable relative to the base about a first axis;
- an intermediate lever being pivotable relative to the base about a second axis in response to movement of the first lever;
- at least one cutting element arranged along a cutting plane, the at least one cutting element being configured to selectively engage the sheet of paper;
- and
- a drive lever actuable by the intermediate lever to move the at least one cutting element relative to the base, the drive lever being pivotable relative to the base about a third axis parallel to the cutting plane.
A paper processing tool comprising:
- a base defining a sheet insertion area;
- at least one cutting element arranged within a cutting plane and movable relative to the base to perform a cutting operation;
- a first lever pivotably coupled to the base and rotatable about a first axis, the first lever including a handle portion remote from the first axis;
- an intermediate lever pivotably coupled to the base and rotatable about a second axis, the intermediate lever being actuable by the first lever, wherein the first axis and the second axis are positioned on opposite sides of the cutting plane;
- a drive lever coupled to the intermediate lever and rotatable about a third axis parallel to the first and second axes, the drive lever being actuable by the intermediate lever to drive the at least one cutting element.
