It stays flat but cuts very deep wider spaced scratches than synthetic coarse stones which are easier to remove the scratches of.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003e\n\u003c\/p\u003e\n\u003cp\u003eIt especially is great for flattening finer finishing stones, especially natural finishing stones. This is our go-to for flattening natural finish stones here in our shop, as we are using a number of different natural stones weekly. Natural stones will generally not need as much flattening done as a synthetic stone.\u003c\/p\u003e\n\u003cp\u003eNatural stones \u003cspan\u003eshould still be smoothed over with a natural nagura after using this flattener.\u003cspan class=\"Apple-converted-space\"\u003e \u003c\/span\u003eThe deep grooves made by the diamond plate in the flattener will reduce the efficiency of the natural grit stones if they are not smoothed away.

These are excellent for wide and single bevel knives as well as double bevel.\u003c\/p\u003e\n\u003cp\u003eIf you find yourself working for more than 5 minutes with a 1000 grit stone chances are your sharpening will improve by adding a coarse stone. This 400 stone is great for quickly bringing back dull edges or for helping in thinning and repair. For very drastic chips or sculptural overhauls of thick blades a coarser stone might be necessary but this stone does a huge amount of work. We found it cuts fastest with a thin watery mud and a bit shallower and slower with a dry layer of slurry. For longest lift be sure to flatten during heavy projects to avoid digging deep furrows into the stone.\u003c\/p\u003e\n\u003cp\u003eNaniwa Chosera Pro stones have a high concentration of a very evenly graded grit bonded in a magnesia binder, they are on the boundary between a hard and soft stone leaning on the harder end.\u003c\/p\u003e\n\u003cp\u003eBecause magnesia binder can dissolve we recommend a short soak of 15 minutes only.
