at least one permanent magnet mounted in an inner cavity of said blade-mounting portion adapted for magnetic attachment of the back surface of the blade-mounting portion to the side surface of the knife blade, and
at least one other permanent magnet mounted in an inner cavity of said spine-mounting portion adapted for magnetic attachment of the spine-mounting portion to the spine of the knife blade.
2. A magnetic knife wedge attachment according to claim 1, wherein the blade-mounting portion has three permanent magnets.
3. A magnetic knife wedge attachment according to claim 1, wherein the at least one permanent magnet has a disc-shape and is retained in a circular cavity formed in the back surface of the blade-mounting portion by a threaded screw.
4. A magnetic knife wedge attachment according to claim 1, wherein the at least one other permanent magnet in the spine-mounting portion has a bar shape and is retained in a bar-shaped cavity which extends a substantial portion of the linear length of the spine-mounting portion.
5. A magnetic knife wedge attachment according to claim 1, wherein the spine-mounting portion has a thin profile that does not protrude beyond the knife spine so as not to impede smooth slicing of food material, furthermore so as not to interfere with user sightlines to the opposite side surface of the knife blade from the side surface on which the wedge device is mounted.
6. A magnetic knife wedge attachment according to claim 1, wherein the blade-mounting portion has a height in the direction perpendicular to the knife’s longitudinal axis that does not protrude below the lower blade edge when the wedge device is mounted at an intermediate portion of the knife blade spine.
7. A magnetic knife wedge attachment according to claim 6, wherein the height of the blade-mounting portion in the direction perpendicular to the longitudinal direction of the knife blade is a minimum of 1.0 inches and a maximum that does not exceed the height of the knife blade.
8. A magnetic knife wedge attachment according to claim 5, wherein the thickness of the blade-mounting portion at the thickest part of the wedge shape is a minimum of 2 mm and a maximum that does not exceed a girth of the knife defined by boundaries determined by the knife handle at its widest width.
9. A magnetic knife wedge attachment according to claim 1, wherein the at least one permanent magnet is retained in the blade-mounting portion by a plastic cover formed by thermoplastic staking, so that the back surface of the blade-mounting portion is kept smooth and easy to keep clean.
10. A magnetic knife wedge attachment according to claim 1, wherein rounded corners are provided for smooth curved transitions between the lower longitudinal edge and the lateral edges of the blade-mounting portion.
11. A magnetic knife wedge attachment according to claim 1, wherein friction lines are provided at upper corners of the wedge attachment body to be used as gripping surfaces for installing or removing the wedge attachment body on a knife.
12. A magnetic knife wedge attachment according to claim 1, wherein said blade-mounting portion has opposite lateral edges that have beveled surfaces tapering to sharp edges so as to form a wedge shape around the lateral edges of the front surface of the blade-mounting portion.
The claims below are in addition to those above.
