This nagura works up a nice fine slurry. It appears to be harder than other naguras. Lubricates the stones well...

Natural Nagura is a MUST for a Natural Finish/Polishing Stone, like Ohira High Grade (approx. 9-10k grit) and Honyama (8-9k grit)natural stones. Don't use synthetic nagura on natural stones; somehow it is not the same. I use it in a combination of circular and up-and-down motion to further smoothen the stone's surface and also to create a slurry for my yanagi knives. Slurry makes the yanagi knife glide effortlessly over the stone, also helps in polishing action. Without slurry, yanagi knives tend to get stuck over the stone or do not glide well (which may be dangerous as you may end up having cuts in your fingers). As for double bevel knives, like a chef's knife, I use nagura just to clean the surface, then wash it off so that narrow blade road grabs the stone, increasing stone's feedback. However, some prefer washing off the slurry for all kind of knives; or they create slurry out of stone itself bu using a fine diamond stone. Try both ways, and you guys decide.

A Natural Nagura is a must for a nutural finishing stone, like Ohira High Grade and Honyama stones. I apply a combination of circular and up-and-down motion to smoothen the stone surface and to create slurry for my yanagi knives. I find slurry helpful on yanagi knives, because it helps yanagi glide over the stone and also facilitates extra polishing. Without slurry, a yanagi tends to get stuck on a natural finishing stone. On the other hand, I wash the slurry off when I finish my double bevel knives, like a chef's knife, because slurry decreases stone's feedback (biting into blade) on small blade road of a double bevel knife.

Picked this up for woodworking. I have a J-Nat that is hard and tends to skip when flatting the backs of planes and chisels. This nagura creates a fine smooth paste that makes the tool slide easily on the stone without skipping. It creates a very fine matte finish. I didn't use this stone much up to this point but the finish and edge it creates with this nagura is amazing. I thought this stone was low quality but used with the nagura, I have to say I'm impressed.

Creats a nice and creamy slurry(fast) on my Nakayama.
Have only used it on a Iwasaki Sweden steel kamisori and Konosuke White #2 Kiritsuke/Gyuto 240mm yet. But I am very happy with the results.

If you own a natural stone that isn't the fastest on giving up the mud like the Jyunsyouhonyama (which I own) then you should get one of these. I recently used it on the Jyunsyouhonyama and it quickly gave me a good starting point. After a few passes I had a good mud worked up. Before hand it would take a very long time. So if you have hard stones that don't make mud very fast pick up one of these nagura's and it will help. As usual great shipping and of course Mark is awesome as well.

So far this nagura has been fun to use. While some suggest not to mix natural with synthetic's (different shapped abrasives and such), I picked up 2 One the use on J-Nats and one for synthetics. Both have produced good results. I also got a great haze off my Shapton GS 1k and 3k with the use of this nagura. I find this one a bit hard and rather smooth.
