Abstract: In a cutting device, which is more particularly used for cutting laid floor coverings, which are preferably fixed flat to the substrate and having a chassis, provided with support means for support on the floor covering, in which the chassis carries at least one cutting tool, which can be transferred into a working position and where the cutting tool is in cutting engagement with the floor covering, the cutting tool is rigidly coupled to the bearing surfaces of the support means in the working position.

Abstract: The shaft parts of a laying knife are pivotable against one another in scissor-like manner with a joint for opening purposes and in the use position are prevented from rotating by a plug-in bolt constructed as a blade magazine and are prevented from spreading by front and rear locking devices, a rear knocking surface of the handle shaft being continuously formed by a single shaft part. This leads to very simple operation with high stability of the handle shaft.
