This stone is exactly the same as the regular #320 Cerax but is an extra 20 mm thick which helps it last even longer, great for working professionals who sharpen their knives regularly or those who are tasked with sharpening for family and friends.
A #320 grit stone is perfect for knives that haven't seen a whetstone for a while. It will help you achieve a new edge on your knife very quickly but will need refining on finer grit stones as the edge left after a #320 grit stone will feel almost serrated and rough.
Suehiro's Cerax line of stones are one of the most reputable synthetic stones available. They have wonderful feed back, Develop a beautiful slurry, cut fast, stay flat a long time and require no soaking and they're effective with any type of steel; what more can we say. We use the Cerax line to sharpen all the knives that come into the shop to be sharpened and we love them. Each stone includes a rubber stand that will keep the stone from sliding around on what ever surface you're working on and a Nagura stone (dressing stone) which will help pull steel out of the stone as it gets clogged up.
For best results soak your stone in room temperature water for 10-15 minutes before use or until the stone stops bubbling and water pools on top of the stone.
