Abstract
A cutting board for food products which is composed of a plurality of abrasive conical inserts arranged in parallel rows on a support so that a knife blade may be drawn along the channel formed between adjacent rows to sharpen the knife blade on both sides by contact with the inserts. The inserts are separately fabricated and mounted in tapered openings formed through the support.
Claims20
A method of fabricating a cutting board for cutting food products and which is characterized by the ability to sharpen the knife during use, and comprising the steps of
- fabricating a generally flat support which defines an under surface and a top surface which are generally parallel to each other,
- fabricating a plurality of inserts formed of an abrasive material, with each of the inserts having a base, a vertex located centrally above the base, and a peripheral surface which extends downwardly from said vertex to said base in an inclined direction,
- forming a plurality of openings extending through said support, with the openings being configured to closely match the cross sectional outline of the inserts and being sized so that the inserts may be inserted into respective openings and retained in a predetermined position with the vertexes extending above the top surface of the support, and wherein the openings are positioned such that upon the inserts being so inserted into the openings the inserts are disposed in a side by side relation and define at least one channel between adjacent inserts along which a knife blade may be drawn such that the knife blade is sharpened on both sides by contact with the inclined peripheral surfaces of the adjacent inserts,
- inserting the inserts into respective ones of the openings so as to assume said predetermined position, and then
- securing said inserts in said openings.

- fabricating a plurality of inserts formed of an abrasive material, with each of the inserts having a base, a vertex located centrally above the base, and a peripheral surface which extends downwardly from said vertex to said base in an inclined direction,
- forming a cavity in the support which extends into the under surface of the support and terminates short of the top surface so as to define a generally flat downwardly facing internal shoulder and a bridge formed between the shoulder and the top surface,
- forming a plurality of openings extending through said bridge, with the openings being tapered so as to closely match the cross sectional outline of the inserts and being sized so that the inserts may be inserted into respective openings and retained in a predetermined position with the vertexes extending above the top surface of the support, and wherein the openings are positioned such that upon the inserts being so inserted into the openings the inserts are disposed in a side by side relation and define at least one channel between adjacent inserts along which a knife blade may be drawn such that the knife blade is sharpened on both sides by contact with the inclined peripheral surfaces of the adjacent inserts,
