Fallkniven–makers of the famous F1 Pilot’s Survival Knife–recently released a new field sharpening stone. With two models measuring 3 inches and 4 inches, the sharpening stone is just 1 inch wide and 1/4 of an inch thick. This makes it perfect for most kits–including EDC kits–or even a pocket.
One side features a 25 micron industrial diamond coated surface for when a courser stone is needed. Flip it over and find a ceramic stone for polishing up and putting a final edge on your knife.
For that extra touch, Fallkniven has included a leather sheath to keep your stone clean and protected.
