Although the technique persists today, it is suspected that it must have appeared in very ancient times, perhaps with the first brass instruments, in the Chalcolithic.[11]. It is one of the steps of a laminar extraction method, which means that by itself it has no value, since it requires a previous preparation of the core and continuous maintenance gestures of the same (done this way, the work is very similar to that of a stonemason with his mallet and his chisel).

In practice, these elements give the craftsman greater control over carving, in easier-to-direct results, and in more precise and defined varnishing; in short, the carving is more efficient and its results more effective: Artifacts carved with a soft hammer have a much finer finish than those where only the hard hammer has been used.
