Abstract
A blade sharpener for manual use includes a base, and at least one sharpening device pivotally attached to the base. Each sharpening device has a channel for receiving a blade to be sharpened. A second pivotally attached device may be sharpening device or a guide. The two devices are pivotable independently of each other thereby accommodating any curvature of a blade to be sharpened as the blade sharpener is moved along the blade. A blade sharpener for use with a powered rotary tool includes a main body having a bore for receiving the powered rotary tool, and a channel for receiving a blade to be sharpened. A guide having a channel is pivotably attached to the main body to accommodate any curvature of a blade.
