| A portable, handheld envelope opening device is disclosed. The envelope opening device has a head portion and a handle portion. The head portion includes a slot defined by a pair of opposing walls and a base plate. The walls being spaced so as to guide the passage of an envelope and preferably are slightly angled to provide a tapered insertion end. A pair of rotary discs disposed within the head portion adjacent the base plate intersects in partially overlapping fashion along a centerline of said slot. The discs are spaced and positioned adjacent the base plate. The first disc includes a cutting edge, and the second disc is adapted to urge the envelope into engagement with the first cutting disc to sever a marginal edge of the envelope to expose the contents. A motor is coupled through a gearbox to the rotary discs to drive the discs. A switch is used to couple the motor to a battery power supply. In one embodiment, a decorative edge is applied to the envelope but the cutting disc by providing a sawtooth or undulating cutting edge on the disc. | ||||||

| A hand-held fluid power-operated shears characterized by a body (10) including a pistol grip handle portion (11), a blade-receiving recess (12) and a cylindrcal cavity (30) with a removable cover over the blade-receiving recess (12). One of a variety of different size and design pairs of interchangeable shear blades (13, 14) may be installed in the blade-receiving recess (12). The blades are pivotally connected, and each has a forward cutting section projecting forwardly of the housing and a rearward extension, the extensions being removably received in the blade-receiving recess to hold one blade fixed while permitting relative movement of the other. One end of a piston rod (32) is fixed to a piston (31) provided in the cylindrical cavity (30) for reciprocal movement therein. The other end of the piston rod is in direct detachable engagement with the rearward end of the extension (22) of the relatively movable shear blade. Fluid flow passages (41, 42, 43, 44) are provided within the body (10), being adapted for connection to a source of fluid under pressure and in communication with the cylindrical cavity (30) on opposite sides of the piston (31) for introduction of fluid thereto and exhaust fluid therefrom. Valve means are provided for controlling flow of fluid through the shears. Power trigger means (57) which are operable from the pistol grip handle (11) are provided to actuate the control valve means (51) and safety trigger means (63) are provided operable from the pistol grip handle (11) to prevent accidental operation of the power trigger (57). | ||||||
