That would be a question better asked to an engraver I guess. But yes, it is a tool that lays put the evenly spaced shallow lines.
I once gave Geoffroy a new screw to engrave at one of the shoots and it had the fine shadow lines on it like that. He could not do it there and had to take it home because he said he did not have the “comb” with him to do it.
