Claim:
A folding knife, said folding knife comprising: (A) a blade, said blade comprising: (1) a first blade side, said first blade side comprising first and second angled bevels, said each angled bevel comprising an angled bevel surface, said each angled bevel surface comprising an angle relative to a centerline of said blade, wherein said each angle is greater than zero degrees, and a remaining surface of said first blade side may have a first flat surface, wherein said second angled bevel surface is disposed between said first angled bevel surface and said first flat surface; (2) a second blade side, said second blade side comprising a flat indentation laterally disposed along said second blade side, said second blade side further comprising a raised flat bevel, said raised flat bevel comprising a second flat surface, wherein said second flat surface substantially comprises a first portion of the centerline of the blade and said second flat surface meets said first angled bevel surface to form a sharp cutting edge; (3) a sharp edge, wherein the sharp edge is formed at an intersection of the angled bevel surface of the angled bevel and the flat surface of the raised flat bevel, (4) a second edge, wherein said second edge opposes the sharp edge, wherein the centerline of the blade extends from the sharp edge of the blade to second edge of the blade, and (5) a spacing detent disposed on the second blade side along the second edge of the blade, wherein the spacing detent comprises a spacing detent surface and wherein the spacing detent surface substantially comprises a second portion of the centerline of the blade, wherein said spacing detent surface serves as a guide for sharpening the raised flat bevel; (B) a blade housing comprising an interior and an exterior, said interior comprising a first interior side and a second interior side, wherein said first interior side faces the first blade side, and wherein the second interior side faces the second blade side; (C) a folding element connecting the blade to the interior of the blade housing, wherein said folding element is operable for opening the blade out of the blade housing, and is operable for closing the blade into the blade housing; and (D) a sharpening element comprising a first grinding surface, wherein the sharpening element is connected to the second interior side of the interior of the blade housing, wherein the first grinding surface of the sharpening element is parallel to the centerline of the blade, and is parallel to the flat surface of the raised flat bevel, when the blade is closed into the blade housing, wherein the first grinding surface of the sharpening element is adapted for grinding the flat surface of the raised flat bevel under a condition selected from a group consisting of: (1) as the blade is closed into the blade housing, and (2) as the blade is opened out of the blade housing.
