Abstract
A cushion back cutter includes finger holes that are shaped to make blade changes and adjustments faster and easier. The cushion back cutter includes a center plate with a recess forming a blade pocket for holding a slotted razor blade. The center plate includes a finger opening for removing a slotted razor blade. The finger opening, which may be non-circular, crosses an upper wall of the blade pocket that supports the blade. A first side plate attached to a first side of the center plate covers the blade pocket in the center plate, and includes a blade window for removing a slotted razor blade from the blade pocket of the center plate. A second side plate is attached to a second side of the center plate, which also includes a finger opening.
