Abstract:
A sharpening tool, comprising:a) an elongated body having a front end and a handle end, said front end further comprising a top area for insertion of a workpiece blade for sharpening; b) said front end including an inner planar mounting surface and an outer planar mounting surface, said mounting surfaces lying on spaced parallel planes with respect to each other; c) said front end further including two linear inner restraining structures associated with the inner planar mounting surface; d) said front end further including two linear outer restraining structures associated with the outer planar mounting surface; e) a first blade engagement member having upper and lower planar surfaces and a plurality of linear edges, the first blade engagement member lower planar surface detachably mounted to the inner mounting surface, at least two of the linear edges engaged by the inner restraining structures, said first blade engagement member further having a thickness less than the distance between said mounting surface spaced parallel planes; f) a second blade engagement member having a planar surface and a plurality of linear edges, the second blade engagement member planar surface detachably mounted to said outer mounting surface, at least two of the second member linear edges engaged by the outer restraining structures; wherein at least one first member edge and at least one second member edge are overlapped and spaced from each other and define a cutting angle having a bottom vertex and two top endpoints within said front end top area for sharpening a workpiece blade; and wherein said cutting angle is a fixed value, said value held constant by the restraining structures, which constrain movement of the sharpening members relative to each other.
