<p>The tool has a rectangular plate shaped profiled part (103) pushed into another rectangular plate shaped profiled part (100) such that a removable blade (106) is inserted between the profiled parts and held in profiled plates by friction. A rectangular plate shaped core (105) is positioned between the profiled parts. Each part includes an oblong opening (110) co-operating with a hole (111) produced in the blade to enable the blade to be removed from the parts. The blade includes a shoulder shaped to prevent the material penetrating between the blade and the former and/or latter parts.</p> |
