Abstract: This invention is directed to solving the problem of matching first and second roll-portions of grouted-tile-pattern linoleum roll stock along the longitudinal edges thereof, so as to maintain the overall repeating grouted-tile pattern ("field") without showing the joint. The problem is solved by a remarkably simple implement for cutting the grouted-tiled-pattern linoleum roll stock along a longitudinally continuous grout line with a manually operable blade means, by making no measurement other than visually inspecting the width of the grout line through spaced apart apertures in an elongated relatively thin metal laminar strip member, and positioning its longitudinal edge, nearest the apertures, on the salvage edge in such a way as to leave a predetermined width thereof when cut with the blade's manually guided edge.
