Thread: 1000 grit stones

It is good to know just the names are different not the stones. I could have bought them with the bases in 20mm for cheaper then what I paid for them not in bases,can't understand that. I purchased the 20mm stones not in a bases as I figured I would be able to lap both sides and maybe designate one side for sharpening other things like kitchen knives.

I sought out the older style superstores because I was replacing older worn down versions and I had read that some people had issues with stones warping. I'd never had a worry with any of the superstores on base, so I stuck with them. As far as using both sides, I guess you could do it and I can't see why it wouldn't work. Either way naniwa make great hones so you should be right. The only one I didn't mention was my 1k stone is the 25 mm Chosera, also the model on a base, it's a great hone.

This Is the 12000 grit stone I noticed its not a super stone. Did I purchase the wrong one.

That is the right stone, it was called the Super Stone, in USA, but now labeled the Sharpening Stone.

The Sharpening Stone and Specialty Stone are sold in the USA in 12k, they are different thickness, but both are 12k.

It is still sold and called the Super Stone in Asia… Don’t know why they keep changing the name.

Here is the full Naniwa line, from the Naniwa web site.

I Think They Did Tweak The Binder For The US market. I think it was the Chosera line that had problems with crazing due to climate differences between Japan and the US. So technically they should be better if anything because the new ones reportedly hone the same as the old.

I'm in eastern Australia, and I have both Chosera and superstores, our climate is temperate, say a cold day in mid winter would be 14 c, hot days in summer 35+ c, mostly humid, I've never seen ice ever on the coast. Not even frost in winters depths.

These arrived friday do I lap the stones wet or dry. Im still waiting on the other stones but can I sharpen razors on 1k naniwa 4/8k norton 12k naniwa progression until then or do the grit ratings not match up. I hear there is a difference how American and Japanese stones are rated.

There is a slight difference in the grits between Naniwa and Norton in the mostly the 8k, (Norton’s are a bit finer), but not enough to make a difference, especially if you finish on the 12k or Naturals.

It does not matter.

Lap stones wet, soak the Norton’s and lap under running water. Wash the swarf off the diamond plate frequently.

Mark your grit, lap it off and remark the grid and it should lap of in 2-3 laps if the stone is truly flat. Don’t just lap off a grid once and expect that the stone is flat.

Don’t forget to bevel or round the edges.

This. They're rated on the same scale, Naniwa stones are just a bit finer. By the time you're done with your final stone all the stria from stones previous to it should be gone, so it won't make any difference that a Naniwa 8K is slightly finer than a Norton 8K.

Only thing I might add is that you may want to hone a chisel or run a screwdriver shank over the surface of the diamond plate while it's wet before using it to lap your stones. That'll knock down any high diamonds and give a smoother result with fewer deep surface scratches.
