The 'Hang Over' ledge prevents trapped yarns as the straight edge makes floor contact away from the cutting line. This helps assure better seam appearance by preventing short cut yarns. Corrugated back prevents creeping and allows sliding in a straight line direction. The No. 24-HOSE has three top dimples for easier sliding of the straight edge using the thumb and index finger. All three have a 45 Degree miter at both ends to permit cutting into corners right-handed, or left-handed, and are excellent for use with the No. 295 Uni-Cutter. A hang-up hole is provided in one end for the Nos. 48-HOSE and 75-HOSE. All are 2-3/4" wide x 5/16" thick and have a clear anodized finish.
