Abstract

A cutting tool for separating beads of adhesive, with a U-shaped cross-section consisting of two flanks connected by a web. One flank is a sickle-shaped blade and the other is employed to attach the tool to an oscillating driveshaft. The center of curvature of the sickle shape extends toward the point at which the cutting tool is secured. The web between the tensioning shank and the blade may have ridges. These ridges extend to the sides of the tensioning shank and blade. The web is longitudinally curved between the tensioning shank and the blade, and has round edges.
