This carpeting tool is used to cut two pieces of carpet at the same time when they are overlapping to ensure that they are cut in a matter that will allow them to line up nicely to cover a floor. This tool is only needed if the room is so large that it requires more than one piece of carpeting to be covered.
A seaming iron is used to activate seam tape before a carpet seam in laid on top of it. The iron is placed on top of the tape, not the carpet, so that it can activate the adhesive and then the two pieces of carpet are butted up against each other atop the activated seam tape.

Heavy duty gloves protect your hands from getting cut.
