An elongate sharpening element extends along the cutting edge wherein the sharpening element will be progressively contacted by the blade with each cut, thereby sharpening the blade.
Claims2
A cutting table comprising:
- a table body having a planar table surface,
- said table body having
- a linear cutting edge comprising a metal insert having an upper surface parallel to the planar table surface and a vertical surface that forms a sharp corner with the upper surface,
- a cutting blade moveably attached to said table wherein said cutting blade progressively contacts said cutting edge for making a cut,
- a coil spring urging the cutting blade towards the linear cutting edge, and
- an elongated sharpening element comprising tungsten carbide embedded into the table body of said cutting table with a surface of the elongated sharpening element extending at a gradual angle away from the vertical surface of the linear cutting edge, said sharpening element positioned below and extending along said cutting edge wherein the coil spring also urges said cutting blade to progressively contact said sharpening element at a gradual angle for sharpening said cutting blade with each cut.
