ABSTRACT:
An elongated tool (10) includes an elongated recess (32) which extends along the full length of the tool (10). A feed strip (12) on a side of a sheet of computer paper (14) is received within the recess (32). The user moves the tool (10) to lower a grip means (38, 40) carried by the roof of the recess (32) into clamping engagement with the feed strip (12). One hand of the user is used for manipulating the tool (10) as described while the opposite hand of the user is used for applying an upward and rearwardly tearing force on the sheet (14). This causes tearing along a line of perforations (20) which is contiguous a side edge (34) of the tool (10) when the feed strip (12) is within the recess (32).
