a main body configured as a handle, the main body comprising a base and multiple members extending from a first side of the base, wherein at least a first gap and a second gap are defined between the multiple members, the first gap and the second gap are separated by at least one of the multiple members, wherein a longitudinal axis is defined through each of the multiple members, the first gap and the second gap;
a first sharpening device positioned in the first gap, wherein the first sharpening device is pivotally attached to at least two of the multiple members and pivots about the longitudinal axis,
wherein the first sharpening device has a first channel extending through an end opposed to that disposed in the first gap,
wherein the first channel extends along a first line parallel to the longitudinal axis and is configured to receive a portion of a blade to be sharpened, and wherein a segment of the first channel is defined through a first sharpening bit mounted in the first sharpening device; and
