Every campsite should have a roaring fire and a sharp knife, and the Sharp & Spark Tool from 12 Survivors can help you achieve both. This handy gadget has coarse and fine triangular blade sharpeners, along with diamond-coated serration and manual straight blade sharpeners. A leather strop is provided for removing burrs and giving your knife edge a final polish. Also included is a magnesium fire starter that produces a shower of sparks when struck with a knife blade (the back of the blade, not the nice edge you just sharpened!) The Sharp & Spark is pocket-sized and has a hole for a lanyard.
