The housing has a spindle that accepts a spool of a roll of tape. The spindle has retention fingers that can either exert pressure against the spool or the retention fingers can connect with a detent on the inner surface of the spool. Biasing alignment fingers are built into the housing to exert a spring pressure against the roll of tape in a direction that is substantially parallel to the spindle to aid in registering an edge of the roll of tape with an outer edge of the housing. A base surface of the device has an opening through which an end of the roll of tape exits. The tape rides over a fixed or movable wear surface adjacent to the opening. A cutting edge is substantially adjacent to and pointing away from the opening.
