ABSTRACT:
The invention provides a device for cutting open envelopes and punching filing holes into documents, and includes a body coupled to a base, the base having a two-section feeding surface along which an envelope, or other one or more documents are introduced into the device. The base is provided with a slot extending across the base, and a cutting blade having at least one cutting edge and being slidably guided in the slot, at least a portion of an edge of the slot in the base serving as stationary counter-edge to the cutting blade. At least two hole punches are slidably guided in a first section of the body; a corresponding member of cutting die holes are located in the body. A pressure-applying handle is hingedly articulated to the body for causing both the cutting blade and the hole punches to move towards the two-section feeding surface. First and second restoring springs respectively cause the cutting blade and the punches to move away from the feeding surface when the pressure-applying handle is released.
