Chroma ST-1800 S whetstone, grit 1000/240, with holder, 180 x 50 x 28 mm

This combined sharpening stone is suitable for coarse pre-sharpening and smaller repairs (grit 240) of the blade as well as for obtaining the sharpness for use (grit 1000). Grinding recommendation: Place the stone in water for at least 15 minutes and always keep it wet while grinding. The water together with the fine stone abrasion acts like an abrasive paste, which enables the grinding process. The knives should be sharpened at an angle of approximately 15°. Only you can sand yourself, because everyone has their own sanding technique. Basically, when moving forward, press lightly at an angle of 15° and then pull back loosely at an angle of 15°.
