Abstract
A blade sharpener for use with a powered rotary tool having a rotatable sharpening element includes a main body having a bore for receiving the powered rotary tool, where the bore extends through the main body along an axis and the main body has a first channel for receiving a blade to be sharpened. The first channel is perpendicular to the rotary axis and opens into the bore to permit a blade to engage the sharpening element. The blade sharpener also includes a guide having a guide channel for receiving a blade to be sharpened where the guide is pivotally attached to the main body to accommodate any curvature of a blade to be sharpened as the blade sharpener follows along the blade.
Claims13
A blade sharpener for manual use comprising:
- 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
- a second sharpening device disposed in the second gap and pivotally attached to at least two of the multiple members to pivot about the longitudinal axis,
- wherein the second sharpening device has a second channel extending through an end opposed to that in the second gap and along a second line parallel to the longitudinal axis.
