A cutting tool for cutting a sheet of compressible fibrous material. The cutting tool includes a blade which forms part of a cutting assembly which is mounted on a supporting base for movement between an upper position in which the blade is located above the material to be cut when the supporting base rests on the material which is to cut to a lower position in which the cutting blade extends below the supporting base. The cutting assembly is biased to the upper position and moved to the lower position by downward pressure from the hand of the operator which also causes the supporting base to compress the fibrous material so that when the cutting tool is moved longitudinally along the upper surface of the fibrous material, the material is cut by the blade.
