tool
Bread plane
The bread plane (1) is used to shave and crumble small pieces of hardened
bread. Originally, this was done to thicken cooking liquid or broth with
crumbled bread, the soupe (2). The tool was mainly spread in France in the
nineteenth century in places where fresh bread could not be baked often or
not all year round. See also the bread slicer. [MOT] (1) Proper name
unknown. Derived from French 'rabot à pain'.
