A rough translation of "Eräkivi" would be "wilderness stone", and that's exactly what this is - sized for easy carry, this little buddy is always ready to keep your blades in shape out in the wilderness. Size 120 x 30 x 10 mm / 4.7" x 1.2" x 0.4".

Made from natural Finnish phyllite, the same stuff that our ancestors used since they first invented a knife that needed maintenance. Naturally, due to the natural nature of the stone, these don't follow any man-made grit values, but that doesn't really matter since each and every Wästikivi will surely keep your blade sharp!

Made by Wästikivi Oy in Orivesi, Finland.
