NANIWA Gouken Arata Professional whetstone #400

NANIWA Gouken Arata, also known as 'Baby Chosera', is the Japanese version of Naniwa Professional and comes in a practical whetstone holder and case for sharpening and safe storage (PTC-001).

It is a coarse, effective stone that sets a new edge quickly. It removes steel fast and leaves an even scratch pattern. It raises a clear burr and gives a good starting point before you move on to a finer stone. It is a medium-hard stone that gives good feedback when you sharpen on it.

The Gouken Arata series suits you if you want to take the next step in knife sharpening and want good stones for your Japanese knives. The stones are easy for beginners and give professional results with good sharpening technique.

At Tomatosharp we always start on this stone to set a new edge and remove small chips along the edge, and it lasts well over a couple of thousand knives before it is 'used up'.

Gouken Arata is a 'splashing' stone, which means you can sharpen straight after putting water on the stone. We still recommend soaking this stone the first time you use it for better results.

Specifications:

• Grit: #400 (coarse)
  
• Type: Splashing stone
• Size: 210 x 70 x 15 mm
• Abrasive: White aluminium oxide

How to use

Put a little water on the surface and it is ready to use. Add a little water as needed so the stone does not dry out while sharpening. Rinse and let the stone dry at room temperature after use.

Maintenance

If the stone starts to cut less well or the surface becomes uneven, you can use a flattening stone to flatten and clean it. We recommend flattening often, ideally after every sharpening, so the stone does not become uneven over time.
