Abstract
The present invention is a blade sharpening fixture, tool and kit for use with logging equipment with a rotary drum that has dozens of staggered blades mounted thereupon. The sharpening tool clamps onto a single blade of the logging equipment while the blade is still mounted on the rotary drum, so that the blade may be sharpened in the field. The sharpening tool includes a sharpening fixture and a grinder. The sharpening fixture includes a blade clamp for clamping onto the blade; a track attached to a sloped surface that can be positioned parallel or perpendicular to the blade; and a grinder connector assembly for securing the grinder securely and slidably to the track.
