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.
