The 800/1000 Grit Diamond Stones are an excellent all-around finishing stone. They maintain the micro-serrations needed for a working edge but leave a refined enough finish to cleanly slice through any delicate material. These are also necessary steps for taking your edge up to a polished finish.
The 1000 grit stone finish is just about perfect for most cutting applications. Your rave about the results you provide them if you finish their knives with these stones.
Each handle has one side of 800 grit (blue) and the other of 1000 grit (purple).
