When brothers [and chefs] Johannes and Joseph Schreiter applied German standards of efficiency to the French practice of
mise en place, the result is the Frankfurter Brett. Both elevated and flush with the heavy duty cutting board, ingredient bins abound; they can be detached or repositioned as desired. Offered in three sizes, the Brett ["board"] is so substantial and serviceable that I'm inclined to consider it an appliance, rather than a mere culinary accessory. [Fun fact: The Schreiters named this invention after the
seminal kitchen design of the early twentieth century.]
