Abstract
A device for opening envelopes includes a movable knife blade which is mounted on a swingable knife holder and is urged towards a complementary edge which is preferably formed by a further knife blade. The movable knife blade is inclined in its longitudinal direction. A cutting operation is effected at the point of engagement of the movable knife blade with the stationary one. Movement of the movable knife blade causes the edge of an envelope be gradually severed. The knife blades are supported on a base part which preferably has, underneath the cutting parts, a removable waste drawer.

An apparatus for opening envelopes, comprising:
- base means;
- an elongate arm supported at a first end thereof on said base means for pivotal movement about a pivot axis and having at a second end thereof remote from said first end means defining a stop surface which faces toward said pivot axis;
- means defining an upwardly facing support surface on said base means which is located between said pivot axis and said stop surface, which terminates in an elongate first cutting edge spaced a small distance from said stop surface, and which extends from said first cutting edge in a direction away from said stop surface;
- means defining a first knife blade which projects outwardly from said stop surface and has an elongate second cutting edge thereon which extends at a small angle to and slidably engages said first cutting edge;
- and a handle fixedly supported on said arm at said second end thereof and projecting outwardly in a direction away from said pivot axis.
