Concrete cutting tool has inset thin metal strips forming cutting lines, for thermal stamping or cutting of thermoplastic films and sheets.As the method does not involve hard pressing, but only simple contact, it can be performed by hand and completely without machines. The concrete tool also has a good heat storage capacity, so that several letters can be stamped with the tool which has been heated, before needing to reheat it. The concrete has a long working life compared with wood or plastic, withstanding temps. of approx. 200 degrees.
