Abstract
Apparatus, systems and methods in accordance with the present invention are related to sharpening blades for rotary cutters. In one illustrative embodiment of a system in accordance with the present invention, an elongated sharpening stone is held at a desired angle between underlying support structures on a base and a securing cap. A planar edge of the stone is exposed in an adjustable channel between the stone and a slidably adjustable sidewall. The angle of the sharpening stone corresponds to correct angle for a sharpened edge on a rotary blade disposed on a hand held rotary cutter, which is inserted into the channel. By advancing the cutter through the channel an edge of the rotary blade may be honed and/or sharpened.
