Chroma ST-1800 L whetstone, grain 1000 / 240, with holder, 180 x 63 x 28 mm

This combined whetstone is suitable for rough pre-grinding and for minor repairs (grain 240) of the blade, as well as for making the blade sharp (grain 1000). 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 act 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. The basic rule is to press lightly with the forward movement at a 15° angle and also pull back loosely at an angle of 15°.
