Naniwa Professional (aka Chosera) 1000 Whetstone

Naniwa Professional stones, formerly called Chosera are Naniwa’s top shelf series loved for their fast consistent finishes. These are excellent for wide and single bevel knives as well as double bevel.

This 1000 stone is faster than the shallow scratches would suggest, it is an excellent stone for either maintaining slightly dull knives or for removing the scratches from a coarser stone like the Naniwa 400 stone when a knife needs more thorough edge re-shaping. When working on wide beveled knives this stone provides a surface that is easy to polish.

Naniwa Professional 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.

Because magnesia binder can dissolve we recommend a short soak of 15 minutes only. The mud generated during sharpening will add cutting material when sharpening wide surfaces of single bevel knives or thinning wide bevel knives, during sharpening small amounts of water can be added to help adjust the sharpening feel
