ABSTRACT:
A blade sharpener includes a handle to which first and second sharpening members are pivotally attached. The handle has first and second receiving slots for the first and second sharpening members, each slot being on a side opposite the other within the handle. The sharpening members are capable of pivoting from a slot engaging position to an upwardly inclined position, the upwardly inclined position being defined by engagement of a stop within the handle. The sharpening members are inclined in opposite directions resulting in their upper portions being in a spaced relationship. When the blade sharpener is not in use, the sharpening members are pivoted into their respective receiving slots forming a compact unit for storage.
