Packaging tools, which, in various embodiments, are adapted to assist a user in applying material from a roll of packaging material (e.g., packing tape, stretch wrap or shrink wrap) to an item or group of items. The packaging tool is typically adapted to move between: (1) a first orientation in which the packaging tool does not substantially restrict the rotation of the roll of packaging material adjacent the packaging tool; and (2) a second orientation in which the packaging tool does substantially restrict (e.g., prevent) the rotation of the roll of stretch wrap tool adjacent the packaging tool. A user typically maintains the packaging tool in the first orientation as the user wraps the packaging material about an item. The user may then move the packaging tool into the second orientation, which allows the user to pull the packaging material tight and separate the applied length of packaging material from the roll.
