Thanks for sharing your thoughts on this stone. Thinking about buying a good coarse but I will take a synthetic for the moment. What is your opinion on flattening stones with a second stone ? Instead of buying atoma plates all the time.

[@naturalwhetstones]

It very much depends. I think conditioning the surface of the base stone, sure a natural nagura works fine. For working down very minor high spots, a natural nagura can work fine. I prefer Omura for this purpose actually if you want natural hand-held nagura to even out stone. If you want to flatten stone and have a lot of work to do, I find Atoma is the best. Some people will go outside and just use the concrete infront of their house - pending it is relatively flat. I do not find I run through the Atoma very fast, I have flattened many many stones at this point with my 140 and never replaced the plate - it is less coarse now though than the 140 plate I keep for knife work. I find the 1200 Atoma does wear out faster, but generally, it makes the job far easier and faster than using a natural nagura and you get pure base slurry. I think the natura's can work though if you put in the time to get the right ones for your job, and you hunt down your high spots.

@@naturalwhetstones Yeah the difference is time at the end. I saw this kind of japanese traditional method with using the 3 stones for flattening ( I think they're all the same grit ), I like the way they do kzbin.info/www/bejne/gp3SiKqcjrmUg7M. As you said Atoma works great I agree, so maybe a 140# will convince me more than my actual 1200# already worn out. Thanks again !

I have a Thai Binsui that I purchased in Chiangmai Mai during a wood carving course. Is this the same as the the Japanese version?

[@naturalwhetstones]

No the Thai Binsui are a Thai natural stone that performs like a Binsui. I have heard they are really good stones!
