ABSTRACT:
A chopping board comprises a slab of polyethylene 400×280×10 mm made as a unitary moulding. The board includes work face2and has a central chopping zone4which drains to a liquid sump62 mm deep in one corner. The top adjacent corner is bounded by intersecting walls8raised 20 mm above the work face2. The wall forms two sides of a triangular aperture10(9×13×9 cm), the perimeter of which together with the lower edge12of the walls are radiussed to avoid any flat area where chopped material may adhere due to surface tension. The contact face12has cavities14to reduce weight and volume of material. A hand grip16also acts as a suspension ledge for a hook.
