Brush, (fr. brosse): the block-brush is perhaps the most important; it represents a bunch of the herb called knee-holm, or sometimes knee-holly(the knee-holy of monastic, and ruscus of modern botanists), used by butchers to clean their blocks, hence called butcher's broom. It is borne in the insignia of BUTCHERS' Company, q.v. under Slaughter-axe, but has often been drawn as a garbe or wheatsheaf.
