Test winner of the large sharpening stone test by Stiftung Warentest.

With its two sides, the combination whetstone from Kai offers a 300 and a 1000 grit. The finer grit allows for easy resharpening of blades by rubbing them evenly under light pressure over the wet stone. The coarser side of the Kai whetstone is recommended for removing small cosmetic defects from the blade. Before using the Kai whetstone, it should be fully submerged in water for about 10 minutes. During sharpening, a light film of water should always be present on the surface of the Kai whetstone. The Kai whetstone can be used for both single-bevel and double-bevel knives.

10. Fällkniven CC4
The developed CC4 grinding stone differs from the standard model in that both sides are made of a ceramic stone. Instead of a coarse diamond plate as in the standard model, the CC4 has an enormously fine ceramic side with 0.1 micron for fine honing - this corresponds approximately to a Japanese waterstone with a 30'000 grit or, according to western grit, approximately 15'000. The finish is really very fine and when the blade is honed after sharpening on the white side, it starts to mirror the surface of the leather. But the blade still remains biting and cuts even fibrous materials very well. If you know the Spyderco Ultrafine Rods (see similar articles), you will notice similarities in the finish of the CC4. The black side remains unchanged and still corresponds to a 600 grit size. The dimensions of the CC4 stone are exactly the same as the old DC4 model. Tip from Yonc: If the white side is clogged by steel abrasion, you can simply clean it with a standard eraser.
