Naniwa Diamond stones?

[dadsavage]

I'm curious if anyone has used this range. Whether for honing or lapping. As I'm looking to buy a stone for lapping / dressing, and the Naniwa diamond stones and ATOMA stones are in roughly the same price range. The Naniwa range seems to offer more choices though which may make it more useful down the road if I expand the collection.

I have the atoma 400 and 1200. fast and don't stick to the hones. I know nothing about the naniwa though. If you are looking to hone on a progression of diamond plates, most people find the edge to be harsh as diamonds cut fast and deep.

Diamonds are for the ladies and lapping, not for razors. I'll have to look into the Naniwa diamond plates...like I needed something else to look into, gee thanks!

I sharpen things other than razors.

That's my link, I think this guy has the complete range. Not certain. Seems fairly cheap, as they go.

I have had the 800k version for a couple of years now, maybe three years. It has a very thin abrasive layer on a very thick alu slab base. It looks like the topping would wear away in no time whereas it is very long lasting - mine still has loads of life left in it.

The topping appears to be a suspension of graded diamonds in a conventioal waterstone binder, it slurries easily.

I use it if I have to resort to a lower grit convetional diamond hone as it removes the deep scratch marks quite easily. It seems to favour softer steels.

I would not use it to lap, though, as the topping is very thin, slurries like mad when seriously abraded, and I dont think it could handle anything harder than itself, which is most of the hones I use.

You never know, though ... if I'm feeling a bit more reckless than usual one day, I might try using it to lap something...

Regards,
Neil

Like I said, like I need "something else" to look into. I can sure see where these would be nice for knives, especially those with some high end kitchen knives. I've still got to get my 20K before I try something like this though...

Anyone else try any of these Naniwa diamond stones yet? Any further thoughts Neil?

Lynn told me the same thing. He said he tried it but stopped because the diamond was too harsh on the blades, his exact words, but you can use something like the DMT 325 to lap your hones.
