ABSTRACT:
An improved, adjustable-blade safety knife of the type having a replaceable, single-edge blade slidably-retained within a single-piece handle against a keeper plate having a tang to engage the blade in a side-by-side assembly for protraction and retraction out of one end of the handle has planar guide member extending forward from the cutting end at one side of the knife at a controlled distance from the blade when the blade is extended and at a slight angle relative to the blade such that, when the face of the guide is brought into contact with the surface of a cardboard container, the blade is constrained to cut the side of the carton at a slightly inclined angle from the horizontal and along a line whose spacing from the container top is closely controlled, thereby preventing injury to the container's contents. A U-shaped retainer clip is disclosed which is slidably-retained in the rear of the handle and cooperates with a laterally-extending pin at about the middle of the handle to define a spare-blade-receiving space within the handle within which a plurality of spare blades may be safely stored for future use.
