Thread: Coarse natural stone?

Oh I know it can do the erasure...but is it a long exercise? I got the binsui because it took too long to erase the DMT green with an Aoto. The Binsui works faster at that than the Aoto, but it's too slow for me.

So....I want some thing that will set a bevel faster than a binsui, but that won't take overly long to erase with the Aoto.

Not particularly. I set a gold dollar factory edge bevel in 30 minutes with nothing but an ikarashi and botan slurry. I typically go to an oohira kiita ( level 3 imo)after, then whatever I want to finish on. I was lucky on both counts as my stones never chip. (Ikarashi and oohira)Too aggressive and you may have that issue. My honest opinion and forgive me if I sound a little bold, is I would consider losing the dmt. I think I would consider the chosera before the dmt. Just a suggestion and I'm no expert, just a hobby honer.

Yep, agree with bill.. you can do the midrange work with slurries on most any hard base stone. I have used coticle slurry on a Lv 5+ jnat for the intermediate work, then gone through the usual nagura progression to the final finish. It seems like some hard steels that tend to chip on a synthetic will remain smooth with the all natual progression. I've fiddled with that idea on a Zulu Grey as well, with similar results though not quite as fine an edge. It's fun to do and can produce a terrific edge but I usually stick with the 1 & 5K Chosera (except for the chippers as mentioned), then on to the jnat just because it's a little faster and the results are more consistent.

Off topic:
Any body can confirm this as a Amakusa ? Got this today but bought it in not knowing about it.....

The spots are similar to those on my white Amakusa. The orange streaks are odd but a lot of them have layered patterning so I'll say it is definitely maybe an Amakusa.

(I'm really only going on the spots!)

I checked several pictures on the web there are Amakusas with these Stripes named Tiger Stripes so they had a look a like....thanks Utopian

I kinda agree with Ron, it looks somewhat like an Amakusa, the streaks throw me off though. I have used one Amakusa as a bevel setter and had mixed luck, it liked some steels and did not like others.
