Abstract: The method includes the steps of placing one edge of a resilient sheet, such as vinyl, in adjacent relation with an irregular or nonlinear edge with which the material is to be mated or fitted. When so positioned, one leg of a device or tool is moved along the irregular edge, the device having a second leg that is clamped in an angular relationship with the first leg. The second leg carries a blade at the lower end thereof so that the blade cuts along a line having the same profile as the edge with which the material is to be mated. Such a procedure severs a relatively narrow strip from the sheet material so that the edge formed on the remaining sheet material corresponds in profile to the edge with which the sheet material is to be fitted. The remaining sheet material is then moved toward the edge to be fitted until the profiled edge meets or abuts the edge to be fitted. The legs of the device are angularly adjustable and one leg thereof includes two longitudinally adjustable components.
