I get this question asked a lot - How much do the various Nubatama stones cost?

So I thought I would post this as a reference. I will also add to this list the pricing for the Nubatama stones for the EdgePro later.

For other sizes, please contact me directly. This would include sizes suitable for KME or the Wicked Edge or for custom applications

I keep these stones in Inventory.

hey Ken, what is the difference between these two?
Bamboo 220 205x75x50 Black $56.35
Bamboo 220 205x75x50 Pink $63.76

I am looking at a progression from the 150 bamboo stone. Which color do you think would be harder/ more uniform grit?

The black one An excellent stone. The 220 green is also softer - good for single bevels. Go for the black. Contact me anytime.

Now you can also comfortably jump to the 320 Platinum as well. The 320 ume green is a bit softer.

Ken,
Every time that I think I want to spring for a Nubatama stone as in a 1000 grit,I am confused at the different names,such as Bamboo,Platinum,or Ume. Then you have regular or hard etc,etc. I realize that a description of all would take a life time but could you clue me in on the 800 and 1000 grit stones in the series and their difference? I am dealing with carbon steels in Japanese knives but a few Germans as well,( choke).

Well, hello!

How about a phone call? 209 612 2790. Just leave a message and I'll call back.

Regards,
Ken

Spring for one - it will last a lifetime for most. Ken sent me a 1200 bamboo stone that is soft and beautiful - as good as my old kikuichi 1K that was the standard for me. Stones are cheap - mine will last through my children's lifetimes. Even a chef who sharpens monthly will only need a new one every 20 years - less than 4 bucks a year. The one I got is 50mm thick - and it's a gem to bring an initial edge with - I thought I would be dead in the water when the fool cats broke my old Kikuichi stone - both the red brick and the Nubatama are great stones - I like the Nubatama just a bit better - it seems just as soft as the red brick but puts a slightly better edge on a knife (less use of the 6K is noted)

Ken can we purchase these stones through cktg??.

Being older and wiser i should have known better !!.. Could a Moderator please delete these two posts of mine.

Unfortunately no. You can however purchase the entire line of Nubatama stones directly contacting me by phone email pm here or in Facebook. (contact info in my signature below).

Ken

I have gotten a few more stones added to the Nubatama lineup to add to this list. As soon as they come in I'll post them here. This includes a 220 Platinum, a 46 and 80 grit stone, etc.

This list still accurate for available EP sized stones, Ken? I know how supply chains all around are disrupted by the pandemic so I wanted to check here. Thank you.

I am still trying to maintain pricing so these prices are vallid. I have a good inventory of most of these stones, but shipping from Japan is getting more difficult and costly.
