The one-of-a-kind One-Step can cut, tuck and secure the carpet down with one easy step - eliminating multiple trips up and down a wall. As the tool is moved down the wall, the star rollers push the carpet into the tack strip to secure it, the blades cut the carpet and the large wheel immediately tucks it in. Use along side a knee kicker and reduce four trips to one. Use it with a carpet stretcher, and eliminate the need to prepare the 'stay' walls prior to trimmimg.
