The cutter is arranged in the following way. Two steel holder on the bottom steel plate are combined so as to form a kind of trough. In the package it fits the narrow — thickness 1,5—2 mm of incisors, which are the easiest to make out of old paintings from a mechanical hacksaw. Pack tightly contracted, on side wall of the trough there are two hex screw heads, and the top is closed with a steel cover on three screws.
