The Guided Field Sharpener is a compact knife and tool sharpener designed for use in the field.Five abrasive steps provide a complete sharpening solution: coarse and fine diamond sharpening plates, coarse and fine ceramic hones, and a leather strop. Built-in 20° and 25° guides establish a consistent angle across the entire edge of the blade. All elements are self contained and require no tools, assembly, or set-up.
