Thread: naniwa specialty stones

Ive honed a couple of razors with the norton 4 and 8k pyramid method and using a 12000 nat finishing stone and a nagura to make a slurry, I just purchased a set of the naniwa stones. Watched Lynn use them on you tube. My question is if i should use the nagura on the 12000 naniwa or just use the stone? when i watched his video he used the 1000 5000 8000 and 12k, not using the pyramid. I guess ill go that route. Mainly ill just be refreshing the razors when the croax and diamond spray no longer works. Thanks

The stones have to be lapped, flat and smooth, diamond plate or 320 grit wet & dry.

If you are refreshing, just use the 8k, the bevels are already flat and set at the proper angle, you just want to get the bevels to meet evenly again.

No need to do a full re-set unless there is damage to the edge. So before you jump in blindly, look at the edge with magnification to see if you need to refresh or repair.

I would not use your natural stone until you have a real good idea of what your synthetic stones can do and you have grit rated you natural stone to see where or if it fits in your progression.

Chances are your natural finisher in not 12K and maybe not even 8K and will just confuse you honing progress.

Thanks for the reply, i bought the naniwa value set and the 1000 from SRD. So if i just need a refresh, just use the 8 k and go to the 12000 naniwa?

Will lap first, i have a lapping stone.

As far as the nagura, do i need to use that for a slurry on the naniwa 12000?

I do plan on just using the naniwa's when i get them. Thank you

You shouldn't need the nagura on the 12k, or any of your other Naniwas. I remember reading a comment (it might be an old one) by Lynn where he said that he never builds a slurry (with a nagura or with a diamond lapping stone) on his synthetics because they tend to release the grit easily all by themselves as you hone. I've been following that advice ever since and got better results this way.

On the other hand, Glen (gssixgun) always creates slurry with his lapping stone in his videos...

My recommandation is, try it with and without and see the difference first hand. This is the best way to find what works best for you.

Cheers.

Ok , i remember Lynn just using the 12k naniwa without the nagura. As for the lapping stone i have the norton. Couldnt afford the dmt just yet. The norton was checked and is flat.

will do and try without making a slurry Thanks for responding

Oh, I thought you said you had a natural 12k. If you have a Super Stone use it.

Actually the 12K Super Stone is pretty aggressive and while many use it as a finisher it can do a lot more. It is a great finisher and very versatile stone. I have even bevel set on it, takes a few laps but it can do it.

Just refresh on the 12K, it will take out most microchips with a bit of pressure then 10 or so finishing laps and you are good. Just look straight down on the edge to make sure all the chips are gone.

I never use any of the naugras on synthetic stones and use a 600 diamond plate. I prefer a more aggressive finish and use a diamond plate, to remove the glaze and get a fresh face on the 12K, I prefer the 600 on the 12K and a 300 grit plate on 1-4K stones. You can use the 300 on all of them but I like the 600 on the 12K and use it as a pre-finisher after an 8K.

The 2x3 credit card diamond plates also work well for refreshing an a stone face, they are a bit small but once lapped flat, they work well and run about 15-20 bucks for the 3 plate set, 320/600/1200 or you can buy them individually. They are handy for all kinds of repairs and a great value.

I've seen references to "a nagura" and "the nagura" but I still don't know WHAT nagura.

What is it?

Thanks Euclid, I was using a nat finisher with my nortons. But just bought from srd the naniwas

Just bought the Dmt 325 to lap them when it arrives.

Thanks all for the post.

I seen Lynn use a nagura to build a slurry on top a finisher if I'm correct. Mixes with the water on the stone when polishing. I've been using it for 10 strokes then rinsing it off then 10 without the slurry just water

Slurry is always better IMO
