The BladeRunner drywall cutter cuts both sides of a sheet at the same time, cutting one step of the usual three-step process. BladeRunner splits into two halves, each with a cutting wheel, that you place on either side of a sheet of drywall to score both sides simultaneously. It will cut up to 5/8-inch drywall. Powerful magnets hold the two cutters in line and the two halves tight to their opposite surfaces while you guide the tool along your cut line. Spring-loaded hinged legs hold the sections apart and fold in when you start a cut at the edge of a sheet, then emerge again as you reach the end of your cut. 866.562.4229.
