U.S. Pat. No. 6,112,417 issued to Hyer; Michael L. on Sep. 5, 2000 titled Precision vinyl & carpet trimmer discloses a hand operated trimmer for trimming an edge of vinyl, carpet or the like being installed on a floor so that the cut edge of the floor covering will lie closely against an adjacent wall. The trimmer comprises an elongate base member and an integral cutting blade. The base member has a generally triangularly shaped cross section, with two of the elongate external surfaces of the base member meeting at a right angle, and the elongate external surface opposite the right angle being a concave surface. The cutting blade is mounted closely adjacent the concave surface and in a substantially perpendicular relationship thereto. Pressure applying rollers are spaced a slight distance from the concave surface so as to define a vinyl-receiving entry location for a vinyl sheet to pass in a longitudinal direction along the concave surface, with the pressure applying rollers serving to keep the vinyl sheet in close contact with the concave surface. The cutting blade is mounted in alignment with the path of travel of the vinyl along the concave surface, whereby upon an installer causing a vinyl sheet to enter the entry location, the external surfaces of the base member meeting at a right angle can be moved longitudinally along the floor-wall intersection. At that time the blade cuts the vinyl at a location coinciding with the intersection of the floor with the adjacent wall, such that the cut edge of the vinyl will reside closely and evenly along the wall.
U.S. Pat. No. 6,226,824 issued to Eric J. Hopson on May 8, 2001 titled Knife with multiple roller wheels discloses a knife with multiple roller wheels comprising an elongate hollow housing adapted to be held and operated by one hand. The housing has a first end with a slot and an opposite second end. A knife blade is provided. A structure is for retractably extending the knife blade from the slot in the first end of the housing to trim a window screen. Two roller wheels are also provided. A facility is for rotatably supporting in spaced apart relationships the two roller wheels. An assembly pivotally connects the supporting facility to one side of the housing adjacent to the second end. A stop member supports the supporting facility in a stationary position, so that one of the roller wheels will extend beyond the second end of the housing to install the window screen in a window screen frame.
