1. A method comprising:
placing a knife, so that a line to be cut is located in an opening between a handle portion of a knife, which partially obstructs a slot, and a protective overhang of the knife, the opening leads to an area adjacent to the slot, the slot being formed by a first portion of a straight cutting edge of a blade of the knife and an interior edge of the protective overhang, the first portion of the cutting edge faces the protective overhang, and the cutting edge having a second portion that extends beyond the protective overhang facing the opening, the first portion of the cutting edge and the second portion of the cutting edge being two parts of the one continuous and straight cutting edge; 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 as the knife is pulled, the protective overhang guiding the line into the cutting blade. |
