Chroma ST-240 whetstone, grain 240, with holder, 210 x 75 x 23 mm

This whetstone is suitable for coarse 240 grit pre-grinding and for minor repairs to the blade. For the actual sharpening, continue with 800-1000 grit. Grinding recommendation: Place the stone in water for at least 15 minutes and keep it wet during grinding. The water together with the fine stone abrasion acts like a grinding paste, which enables the grinding process. The knives should be ground at an angle of approx. 15°. Only you should grind them yourself, because everyone has their own grinding technique. Basically, press lightly with the forward movement at a 15° angle and also pull back loosely at an angle of 15°.
