Round Chosera stones

[fujiyama]

I stumbled upon these round Naniwa Chosera whetstones today. Pretty massive at 220mm diameter. What I think some of you may find intriguing is it's availability in 320 grit.

Anyone use one before?

 

[berko]

i do have the 3k, but havent used it that much yet. the 3k chosera in general is one of my favorite stones. i guess i just have too many other stones and the big size somehow makes it even more hassle to handle it, like getting it out of the last corner of my box and drying it takes alot of space as well...

What's the benefit of a round stone?

If you can engineer it into a low-speed grinding wheel... plenty! Where can I get one?
But as @berko said, not the most practical shape for general handling & storage.

Thanks! Not cheap but just sent them an email to see if delivery to Oz is possible.
Does anyone know of a suitable motor / grinder these could be attached to? They are 220mm in diameter.

I'm UK based, I'd be happy to take delvery here and post it to you in Oz if they don't ship there and you need the stones.

Feel free to PM me.

Thanks for the offer khashy! Let's see how the query goes first. If they do ship to Oz, shipping is very reasonable... once you remove the VAT, it's almost the same as the listed price.

I believe these stones are used to sharpen sobakiri primarily but also for long knives.

I've been watching these a while back as well. I can see one major advantage... since you can simply turn the stone it should be far easier to consume them evenly, resulting in less flattening and waste. The huge surface is probably nice as well, though I'm not sure how much more of it you can actually use (with handles / bolsters getting in the way).

Nice stones Berko! I love the 3000 as well.

That's the same website I was looking at, Marek. Did you end up placing an order?

That makes a lot of sense Dave! Thanks for the photos. These would be very useful on knives 300mm+.

They answered my email but no go for Oz. They only ship to EU & the US. Perhaps Canada - guess you need to ask. I'm going to investigate trying to use it as a wheel before ordering. I'll be in Europe soon so I could pick it up then if I go ahead.

Axes are often sharpened using round stones, but usually these are smaller in size.

You can put those stones on an old vinyl record player and sharpen your knives the lazy way.

Always thought these would work on a pottery wheel

If you happen to have a pottery wheel.. Heh.. Find a way to secure the stone...

Does anyone have a place in the US to get these wheels?? I don't mind buying UK, but the postage and
customs hassle would be good to avoid..
Thanks
Bill

Have you tried looking in Amazon? I found 2 Chosers grit stones on the CDN site... Not much selection... But they are around..

Amazon is a good suggestion, but no go with the round stones.
