The multiple lining tool is a burin chisel used in engraving with multiple cutting blades for making parallel lines to create a hatching effect.
The multiple lining tool is also called the multiple tool, lining tool,[1] multiliner,[2] liner, shooter,[3] multiple graver, comb, and half-tone comb.
[4] The multiple lining tool allows the engraver to create hatched shading effects[2] by engraving multiple parallel lines at the same time.
[3] It achieves this by having two or more cutting blades,[2] which are available in different grades or sizes,[1] such as the density of lines.
The resulting hatching has a mechanical look.
