This is the new version of the Naniwa Super Stone with new packaging. They are made with a new resin bond and a tighter control of grit particle size. This bonding agent gives the stones two distinct advantages. First, the resin bond allows for a higher concentration of abrasive particles compared with less expensive methods of stone bonding. The higher abrasive levels contribute to the speed and ease of sharpening. Second, these resin bonded stones don't require soaking in water prior to use, just a sprinkle on the top is all that is needed. Do not soak these stones!

This particular 400 grit stone is excellent for establishing a new bevel angle or removing chips from the blade. This stone is the lowest grit you will need if you maintain your edges. If your knife or tool is not damaged or allowed to get too dull between sharpening sessions this 400 would be the coarsest stone you would need.

They measure 210 mm x 70 mm x 20 mm.

We are happy to be the only US distributor of Naniwa Super Stones that come in the larger 20 mm thickness without bases.

This stone produces a good finish for a 400 grit stone.

  400 Naniwa, October 25, 2019
Posted By: HPHH - verified customer

It didn't cut as fast as I was hoping for but, for the price, it's hard to complain. If you absolutely must have an aggressive stone, this isn't it, but for the vast majority of your needs on a low grit like 400, it does the trick and does what it says it does.

  Naniwa Super Stone 400, March 11, 2018

I got the 400 grit stone to fill in the gaps between the other Naniwa stones I have. The 400 is a good starting point for maintained blades. CKTG gets two thumbs up!

  Wonderful!, January 26, 2018
Posted By: Bryce M - verified customer

I was a bit impatient to receive my products, however they arrived very quickly. The staff was very helpful as well. This stone has the feel of a little higher grit range however it will bring even the worst of dull knives back from dead. Make sure you know your angles and pressure when sharpening a knife as this stone does its work quickly. The packaging was wonderful and I probably could ha e punted the box across the yard and still not damaged the contents. The thin packing paper makes for a wonderful sharpness test when you finish sharpening. Will definitely return for future business.

  Fantastic to have in class, January 8, 2018

I love this stone! I put it through my entire knife bag after a busy holiday season. It's fast cutting, slow dishing, doesn't load up fast. I used German steel, blue
