E C Lyons rockers are known world-wide as the finest mezzotint rockers available.
They measure 17.75 cm (7 inches) at their total length, including the stained birch handles, and are made with the highest quality high-carbon tool-steel.
The gauge (screen) sizes are available in 45 (coarse), 65 (medium), 85 (medium-fine), and 100 (fine) lines per inch.
By working the rocker with a rocking motion over a copper or zinc plate evenly in a cross-hatched fashion, one creates burrs that will trap the ink to produce characteristically rich and velvety blacks, which can selectively be burnished away to produce delicate light areas and soft shading.
