Tomonagura is just a pice of stone not coming from Mikawa mine, used to make fine slurry to do finishing work on razors.
On knives a very popular tomonagura is Tsushima, they are not so fine but still can be used for razor honing.

Notice how the description in the link says Tomonagura" and not nagura.
Here is what naguras look like
JNS Stones - Asano Naguras - Japanese Natural Stones

Not saying your stone is bad, if Maksim sold it to you then it will work.

So if i bought a set of 3 Nagura stones for honing, would i still need a Tomonagura for the final finish?
Thanks.

In general yes.

Here are my new Oozuku, tenjou nagura and Tsushima nagura. The tenjou 172g 2160JPY and the Tsushima 2800 JPY. 1JPY= 0.01$
I just shaved with two gold dollar razors. Whenever I try a new stone, the gold dollars are the first ones to touch it. Both bevel set, refined on milky slurry and diluted until very little remained on the stone. Then stropped. One with the Tenjou and one with the Tsushima.
For a moment I forgot they were Gold dollar razors. I shaved yesterday, so, today's shave was against the grain. No irritation, nothing.
They are nowhere near as good as a good tomonagura, but they can deliver a very pleasant shaveable edge. And it was smooth, maybe even more than from tomo nagura, not as sharp, but nice. I'll try them again the next days with an actual razor.

For the nagura question above, I think they get their name from a city in Mikawa province.
For swords, nagura is the actual Mikawa stone, and is used a lot, in base stone sized pieces.
But, nagura also ended up meaning a small stone, I'm not sure how.

My Nagura is quite big and flat.

Looking at your "Slurry Stone" (don't want to argue about the Japanese names)

It could be a bigger brother to one of mine I marked it way back when so I would always remember the name I forgot,,, it is something like Akupisa or Akupika Aku something anyway,,, very very fine, very very soft, but a PITA to make slurry with

Akapin is the word that comes in mind. I unfortunately read way too much before making a purchase.
It's the higher strata of stones, the softest of all.

P.I.T.A had me baffled for about 10mins

Ah.. Job, I didn't recognize the tomo until I saw your second picture. Maksim gave me one of those "yellow" tomo's some months ago and it quickly became one of my favorites. It's good to see that it's available on the website now.

They are very soft, easily produce a thick slurry that breaks down fairly quickly, and are very fine.
I'd say that they are almost like a good koma nagura and yet very inexpensive. Shipping costs might make it impractical to buy just the nagura but if anyone is buying anything at all from the site, he owes it to himself to try one.

Since they are so soft and throw slurry so easily - worthy of the term "mud" - the usual practice is to cut grooves across the face of the stone (as Vasilis showed in his pic of the tsushima) to relieve that suction problem.

Vasilis - it had not occurred to me to shave off a tsushima edge since it seems to be of pre-polisher fineness. Now I'll have to try diluting it down to the point that it's mostly working the base stone and give it a try. Thanks for the idea. Sigh, so many possibilities.. that's the magic of the jnat - more work but more fun!

I would argue diamond plate slurry from a super fine finisher is much finer than any nagura.

Yeah so would I Oz but that argument falls on deaf ears, so I no longer waste my time sometimes you just have to let the horse walk to the water and take a drink

Really? I haven't tried it yet on good finishers, but I guess I have to. If both of you agree on that, it's definitely worth a shot.
