The Cerax 1000 is a high abrasive concentrated soaking stone which is perfect for regular maintenance of your knives. This is a porous, high-friability stone meaning that it needs a short soak prior to use and requires less effort from the user to sharpen. This stone, especially so with single or wide bevel knives, builds up a quick slurry and creates a nice even finish with a nice contrast between soft and hard steel.
