Abstract

A utility knife for retractably retaining a replaceable blade with a body, at least two detents connected to the body and a blade adjusting knife retaining fastener mechanism. The body has first and second portions and a major longitudinal dimension. The first and second portions define a cavity for storing at least a portion of the blade. The blade adjusting, knife retaining fastener mechanism extends through the blade adjustment slots of the first and second portions and is coupled to the blade. The fastener mechanism is configured to releasably connect the distal ends of the first and second portions of the body without the use of tools, and to releasably engage at least one of the detents and to adjustably extend along the blade adjustments slots without the use of tools. Each engagement of the fastener mechanism to one of the stops defines a distinct position of the blade with respect to the body.
