the placing of the knife includes initially placing the knife so that the second portion of the cutting edge faces the line and is exposed to the line prior to the line entering the slot formed by the first portion of the cutting edge and the protective overhang;
moving the knife so that the line moves into the slot;
the moving of the knife includes pulling the knife away from the line so that as a result of pulling the knife, the line moves, relative to the knife, away from the opening in a direction parallel to the straight cutting edge into the slot; and
