ENVELOPE OPENER

An envelope opener having a small body to be manually grasped, with a groove along one edge of the body, sufficiently wide to receive an edge of an envelope to be opened. An oblique knife blade lies entirely within the groove, and a small guiding member projects forwardly from the forward end of the knife blade, to a visible position beyond the edge of the body, so that the guiding member may be inserted between the envelope flap and the rear wall of the envelope, at one corner of the envelope, to guide the top fold or crease of the envelope into the groove, whereupon the knife blade will cut the top fold when the top edge of the envelope is slid along the groove.
