Chroma ST-1 / 6 whetstone, grain 1000 / 6500, with holder, 182 x 61 x 25 mm

This combined whetstone is suitable for producing a working sharpness of grain 1000 and a polish of grain 6500. 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 sharpened 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°.
