The spark sharpener is both a firestarter and knife sharpener!
The handle is created from a ceramic tube that was originally used to insulate wires in residential homes. Ceramic is a great material for honing and sharpening steel. The ceramic handle is protected by a piece of scrap leather that is hand stitched and oiled. This leather also functions as a leather strop, for putting a finer edge on a blade after using the ceramic. Each spark sharpener is fitted with a 5/16” ferro rod and a paracord loop - for fastening a lanyard to, or for hanging.
