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

This combined whetstone is suitable for coarse pre-sanding and for minor repairs, blade size 240, as well as for the use of the grade 1000 hardware. Recommended sanding: Place the stone in water for at least 15 minutes and keep it wet while sanding. The water along with the fine stone abrasion act like a grinding paste, which just allows the grinding process. The knives should be ground at an angle of about 15Â °. Grind only you, because everyone has their own grinding technology. As a rule, with the forward movement at a 15 degree angle, you can easily press and also loosely pull back at an angle of 15 degrees.
