Abstract: A wall edge trimmer for resilient floor coverings comprising: a relatively smooth base surface capable of sliding along the surface of a resilient floor covering laid out on a floor; a relatively smooth front surface lying in a plane substantially at right angles to the plane containing the base surface and capable of sliding along the surface of a portion of the resilient floor covering which is curled upwardly and contacts the lower portion of a wall; a relatively smooth arcuate surface in the form of a quarter cylinder connecting the base surface and the front surface; and a cutting tool on the wall edge trimmer having a cutting edge intersecting the arcuate surface and extending from a point within the wall edge trimmer to a point beyond the arcuate surface, the base surface contacting the arcuate surface at a direct, level, straight-line distance from the vertical plane containing the front surface equal to the arcuate distance from the point of the intersection of the base surface and the arcuate surfac
