Wästikivi Eräkivi whetstone
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.
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!
Instructions of use, as found on the product package:
Moisten the stone with water. Using circular movements, grind both sides of the blade in the direction of the angle of the blade. A knife which is blunter than usual requires stronger handling. The mud emerging on the top of the stone helps the finishing process. Use plenty of water when sharpening harder and blunter blades.
Finally, grind the knife in straight strokes from both sides in a slightly steeper angle than when sharpening the blade (as if you are attempting to carve steel shavings). Remember to use the stone often, so that the blade does not become very blunt.
Made by Wästikivi Oy in Orivesi, Finland.

In my experience it cuts much faster using spit/saliva than water.
Just don't try to use it to establish an edge, you'll need something much more abrasive for that.
If you need to do some serious sharpening get you some larger stones. You can do a lot with 400 and 1000 grits.
