Abstract
A hand tool includes a cutting portion that is attached to a handle by a connecting portion, and is shaped and sized to efficiently separate a core from the leaves of a cabbage head and which will efficiently remove such separated core from the leaves.
Claims3
A hand-held tool for de-coring a cabbage head comprising:
- A) a handle including
- (1) an arcuate butt end,
- (2) a planar front end which has a circular outer periphery,
- (3) an hour-glass shaped sidewall connecting said butt end to said front end, and
- (4) a longitudinal centerline extending from said front end to said butt end;
- B) a shank which includes
- (1) a proximal end embedded in said handle through said handle front end,
- (2) a connecting section extending from said proximal end to an intermediate location and having a length as measured between said handle front end to said intermediate location,
- (3) a cutting portion extending from said connecting section intermediate location to a distal end and having a length measured from said intermediate location to said distal end that is essentially equal to the length of said connecting section,
- (4) a multiplicity of cutting teeth on said cutting portion distal end,
- (5) said connecting section having an arcuate outer periphery and having a center of curvature which is positioned in line with said handle longitudinal centerline, said connecting section having a radius of curvature as measured from said connecting section center of curvature to said connecting section outer periphery and having a peripheral angular extent of less than ninety degrees with respect to said center of curvature, said connecting section being spaced from said handle longitudinal centerline and from said handle front end outer periphery,
- (6) said cutting portion having an arcuate outer periphery and having a center of curvature which is positioned in line with said handle longitudinal centerline, said cutting portion having a radius of curvature as measured from said cutting portion center of curvature to said cutting portion outer periphery and having a peripheral angular extent of more than two hundred and seventy degrees and less than three hundred and sixty degrees with respect to said center of curvature to define a gap in said cutting portion outer periphery, said cutting portion outer periphery being flush with said connecting portion outer periphery and having a radius of curvature that is the same as the radius of curvature of said connecting section.
