Thanked: 104New stone Japanese natural, Ozuku Asagi
This is the Ozuku Asagi natural stone I wrote about yesterday. Like the Wakasa, it is a full sized stone at 212 x 78 x 38 and 3 lb 10 oz or 1664 grms. I also bought this one from Takeshi at Aframes tokyo. since those photos I have now lapped it completely, so the identifying stamps are gone, preserved only by the photos. In my post about the Wakasa,I wrote that this Ozuku was supposedly finer than it, (Wakasa), I can report that it took some lapping, with a good 25 minutes of hard work with an Atoma 600, but once it was flat, I had a brief play with it, with some slurry, and it is a very hard and fine finishing natural. Aframestokyo described it as a hone for finishing razors, and from all accounts it seems to be exactly that. I have a razor in mind to put on this stone, and its a TI C 135 steel, so should respond well to this type of natural. I point out too, that this is a double sided stone, although I haven't lapped the other side yet, but doesn't have the toxic skin, is seemingly the same as the primary surface. Its just another option.
I wrote yesterday I was relieved at how good an edge was obtained from the Wakasa. What it has done though is the normal side effect of once again looking for other 'opportunities' as to possible other jnat acquisitions. Has anyone had any good luck with Shobu stones, sometime known as shoubudani. I have left the most lauded stones alone (Nakayama) as they cost a lot, and a lot of that is on reputation, so I figured I'd rely on advice from a trusted source. I'd still be interested in members views on the Shobu mined stones. I know JNS have sold a lot of Shoubu-dani, at fairly cheap prices compared to the Ozuku pictured. So any views are welcomed. When I do go through with a razor on the Ozuku I will show some pictures of the stone, post lapping, and its colour differences when wet to the Wakasa. One video actually of Keith Johnston, showing a number of different types of stones, and then using a finishing Ozuku in the demonstation , was a great help. As far as Im concerned, Nagura progressions, and tomonagura are a bit above my station at the moment, but at some stage I'll look at them.

I should mention that I sealed the four sides with Shellac, and the same with the Wakasa. ( I left the bottom side alone as it may be lapped and used in its own right)Last edited by bobski; 05-30-2017 at 12:18 AM.

Thanked: 133I have a shoubudani mizu asagi that I like a lot. It is a nice 6"x2" that I use as finishing stone with just water. I flattened mine with sandpaper as I didn't want to risk my plate, went 400,800,1200 to give it somewhat polished feel. I really enjoy the stone but don't have anything to compare it to jnat wise , planning on getting either an ozuku or another shoubudani full size. I enjoy the grey cloudy look some of these stones have.

All of the mines (Nakayama not being an exception) produced stones of various grit size equivalents. If you are looking for a shoubudani finisher you better discuss with a reputable dealer what you are looking for and see whether they can fix you up.

Thanked: 2I too have a Shobu asagi that I got from Keith in fact. It's an excellent finisher and if you can find one like it I think you'd be happy. I do have several finishing stones to compare it with - mostly Nakayama and it holds up quite well against them. Problem is that all these stones are very individual and just because I or someone else likes a certain XYZ stone doesn't mean your experience would be the same. The reputable dealer part mentioned above is important I believe.

Thanked: 104The allure of the natural stones is strong. People get caught up in the romanticism of them. About 18 months ago I went down the coticule path. I'm not criticising coticules generally, but I had no good fortune in them. I bought two 8 x 3 select grades, and another two bouts. After converting half a dozen razors over to their edge I was disappointed badly. The shave wasn't good at all. I'm not arrogant enough to blame the coticule entirely, but I do know how to hone. I sold them at a loss.
Now I've gone back into naturals. I bought the stones above, the Ozuku then the Wakasa. I've gotten great results from both of them, so now I have that confidence to really contemplate getting a few more. If feel, that the noise about them is justified. I remember when I first got edges from the Gok 20 and raved about how sharp they were. They are still the sharpest edges going round! They are acute though, really clinically sharp, one slip and your cut!.
I noticed with my Ozuku that, yeah they were sharp, they did a nice job. Not a Gok 20 edge, but a toned down version, it felt as though I could have closed my eyes and not cut myself. I guess they are more forgiving. That's not a bad thing. Anybody have any conclusions coming off 20k edges?

Thanked: 481I had a similar fight with a coticule. Only bought one, but getting a shaving edge off it was truly a trial. I even started with a blade that was shaving nicely and used the coticule as a finisher only, the stone ruined it. I was surprised to say the least. I did finally get it to work, but it took probably 3 weeks of trial and error. I haven't pulled the stone out since I finally got a good edge off it.
By comparison, I've got a small Shoubudani from JNS that I got a wonderful edge off of the first time I put it to use. Little bit on the keen/nippy side of things, but thats easily fixed by stropping and I'd rank it high on my list of favorite hones.

Thanked: 59Totally feel your pain Marshall, for a long time I felt coticules were for the most part garbage. Then I started focusing in on certain veins and I have to tell you, there are some awesome coticules out there.

Thanked: 481I try hard not to knock them. Just because mine was hard to work with doesn't mean they all are. I'll probably buy another down the road, but I'm not just gonna buy another one from Ardennes sight unseen. I'll wait until I can either try it out, or at least get a known good stone that someone is simply looking to trade off in the classified section. That won't be anytime soon though.
I think I may give that and my Jnat a revisit. I've not used either in a while, I'd like to see how they perform following my 12k synthetic. That was also intended as a response to your question about Shoubudanis too. I'm fond of mine. I almost hate to say it, but the little fella gives my translucent Arkies a run for their money.
I was told they can have little black inclusions that can be toxic/detrimental to honing. My stone has black dots, but they're not detrimental. That's something to be mindful of if you pick one up. But overall I'm happy with it.

Thanked: 104The best advice that I respect is pointing me to acquiring some nagura stones, from Botan to Mejiro to Tomo. It's all a learn for me at the moment, my only plan was to get a few genuine very hard, fine finishing jnats and go to them after a 10k synthetic edge. That's what I've done do far, but of course I'll advance my thoughts by listening to other more knowledgeable folks.
