The knife blade has a side portion proximate the cutting edge which includes a series of adjacent lengthwise corrugations. Each corrugation includes an inclined surface with an edge which extends outwardly beyond the inclined surface of the adjacent corrugation forming a ridge along the corrugation. Food, as it is sliced by the blade, moves across the inclined surface and over the ridge of each corrugation, to release the vacuum formed between the food and the blade, reducing the tendency of the food to stick to the blade. The knife is formed by forming a blade blank with corrugations on one side and metal strips on the opposite side. The metal strips are ground off the opposite side and the corrugated side proximate the edge is lightly ground to form a chisel edge. The blank may be formed by casting 3D printing, forging, extrusion, pressing or another additive manufacturing process.
A knife for slicing food comprising a handle and a blade, said blade having a tip, a side and a cutting edge, said side comprising a portion proximate said cutting edge, said proximate side portion comprising first and second adjacent corrugations extending between said handle and said blade tip, each of said first and second corrugations comprising an inclined surface with an edge, said edge of said inclined surface of said first corrugation extending outwardly beyond said inclined surface of said second corrugation forming a lengthwise ridge along said first corrugation, such that food, as it is sliced by said blade, moves across said inclined surface and over said ridge of said first corrugation, so as to release the vacuum formed between the food and said inclined surface of said second corrugation, reducing the tendency of the food to stick to said blade.
A knife for slicing food comprising a handle and a blade, said blade having a tip, a side and a cutting edge, said side comprising a portion proximate said cutting edge, said proximate side portion comprising a series of adjacent corrugations extending between said handle and said blade tip, each of said corrugations comprising an inclined surface with an edge, said edge of said inclined surface of each of said corrugations extending outwardly beyond said inclined surface of said adjacent corrugation forming a lengthwise ridge along each of said corrugations, such that food, as it is sliced by said blade, moves across said inclined surface and over said ridge of at least one of said corrugations, so as to release the vacuum formed between the food and said inclined surface of said adjacent corrugation, reducing the tendency of the food to stick to said blade.
A method for fabricating a knife blade from a blank wherein the blank comprises at least one side having a corrugated portion and an opposite side, said method comprising the steps of:
A method for fabricating a knife blade from a blank, wherein the blank has a side with a corrugated portion and an opposite side, and wherein the side with the corrugated portion lacks sufficient flat surfaces which could be used to grip the blank to allow grinding of the blank to create a cutting edge, said method comprising the steps of:
A method for fabricating the knife blade from a blank formed by an additive manufacturing process, the blank comprising a blade portion and a handle portion, wherein the blank has at least one side with a corrugated portion and an opposite side, the method comprising the steps of:
