I just came back from Osaka and one of the highlights of the trip was stopping at kitchen supply store and finding a bin of budget scraps of natural stones that I didn't have much information on. This video helped me get an idea, thanks!
Thank you for going through the effort of making this video. The best video of this sort I have ever seen. I have been using and learning about Jnats for years and yet I still found new bits of info here (and just about nothing you have mentioned I would disagree with), plus it’s always a treat to look at someone’s collection! Well done and keep going. I will definitely be pointing people in the various knife and stone groups I’m in to the video 👍👍👍
@@Vart1980 Every once in a while I will sell something from my collection. I may have a Tam O Shanter I am looking to part with. If you are looking for JNAT stones though, none really. There are plenty of good vendors though: naturalwhetstones.com/natural-whetstones/reputable-japanese-natural-stone-jnat-nagura-sellers/
Took me α few sitting to finish it, now I need to start we rewatch to help it sink in. The section on the base stone colors I found very helpful as not all vendors don’t go into that level of detail. Thanks α lot and don’t fear making long videos.
Thanks so much for commenting Jesse and I'm really glad to hear it helped. Knowing the terms is as much for cataloguing the attributes for my own use as it is for understanding vendor lingo!
Theoretically yes, there are stones that are sometimes referred to as "imo-ishi" or potato stones which are homogonous and lack gotogi or kawa. If it is this type of stone all sides could be usable. Take care though that if it is just a stone that barely shows its gotogi, pressure on that side could delaminate the layers.
I have a stone that works fairly well but is probably acidic and causes little rust spots to appear on wide bevels immediately after polishing (and are hard to get rid of). Do you have any method of mitigating this? Thanks!
Your two methods are to try and add a small amount of a basic solution to it (water mixed with something basic) or you can touch up with finger stones afterwards
@@naturalwhetstones Thanks for the reply! I tried some slurry from another natural stone (rubbed with a piece of felt) and it got rid of the little spots, lol. I'll probably experiment more the next session.
Hey Luca, not quite sure what you are asking. Nakayama is a mine rather than a visual property. naturalwhetstones.com/natural-whetstones/japanese-natural-stones-jnats/japanese-natural-stone-mines-list/
@@lucapacchiarotti8014 There is no "best stone" each mines produced stone that can be comparable to one another for sharpening. Nakayama produced far MORE stone than other mines, and as such could be more strict about the quality control. I liken it like this, the same % of stone in Nakayama mine was high quality as other mines on the same geological area (hon kuchi naori) but Nakayama pulled more out, and kept better pieces. This means if you reach into a bin of random nakayama stones vs a bin of a different mine random stones, the nakayama has A HIGHER CHANCE Of being a good stone. However, it isn't assured, there are bad Nakayama stones out there - and other stones that are just as good as the best Nakayama put out. This is why it is very important to work with reputable vendors who will answer questions, test the stone, show you pictures, and are known to supply good quality stones (doing their own quality assurance process). Just because a stone is Nakayama promises nothing. People wish it were different, and like to believe it is superior, so it sells for more and gets talked about the most. There are even some other problems how sometimes Japanese vendors will use the word "Nakayama" like much of the world uses "Coke", as a more generic term for a "nice stone". This can get confusing for westerns and further increases the stock by calling many unknown but good stones "Nakayama". Lastly, to be frank, many stones not from Japanese origin are fantastic for sharpening and a great deal of people would say better than the JNAT stones unless you need a sushi grade edge on your knife. Coticules, Cretan Stones, Hindostans, Washitas are all great options for standard knife sharpening that will tend to be faster than JNATs and deliver fantastic edges. Just something to keep in mind. Similarly, many people prefer Aizus (not a Nakayama stone) for sharpening unless they are doing the very finest of edges!

They're not rocks Marie! They're JNATS!
I have certainly thought the same thing sometimes ;P
Fantastic video, very comprehensive! Keep it up!
Thanks a lot!
hello, what is the name of the white with milk coffee stripes at 45:33? the left one
It is a Tenjyo Mikawa Nagura: ruclips.net/video/Uo0tiJQsD6c/видео.html
Hi just a quick one, aiiwatani koppa is worth to try?
Sure it can be!
If there's no visible Gotogi or Masame to go off of is it possible for all surfacea of the stone (top, bottom and sides) to be used?
Theoretically yes, there are stones that are sometimes referred to as "imo-ishi" or potato stones which are homogonous and lack gotogi or kawa. If it is this type of stone all sides could be usable. Take care though that if it is just a stone that barely shows its gotogi, pressure on that side could delaminate the layers.
@@naturalwhetstones is there any way to identify the gotogi if they're barely showing?

Yep that is always the key!

I think thanks! Haha
Nakayama?
Hey Luca, not quite sure what you are asking. Nakayama is a mine rather than a visual property. naturalwhetstones.com/natural-whetstones/japanese-natural-stones-jnats/japanese-natural-stone-mines-list/
Which is the best japanese stone for sharpen knife
Why a lot of person think that nakayama stone are the best
