Thread: Jnat bevel setter?

I have never tried the interrupted ones so I can't comment, but the continuous surface ones are like running a piece of metal over slick glass. Reminds me of teflon for some reason.

Yeah... that's about how the 220 is. The interrupted are way different. I could tell you ~ how many passes I've given a razor on my F/EF by the SOUND it makes during the stroke. It's that good.


Edit:
I should note that the 220 has SOME feedback the first couple passes after a good brushing (I actually used a synthetic horsehair brush to keep it clean when I first got it and was actually bothering to try and keep feedback on it). The problem really is that as soon as it starts clogging it does kind of hydroplane whatever you're working on... still chews though, so I learned to live with it. Hence the checking on the Chips with a scope. :P

who has a link to the woodworkers forum discussion of Iyo. I'd like to see that if you don't mind Thanks!

Someone would ask... I am not sure if these are the ones to which I was referring (don't have time to re-read them now):

Anyone using Japanese natural waterstones? - Woodwork Forums

Natural Japanese waterstones - Woodwork Forums

Ok, I have read those threads and realized I have no clue (my kids know this already) where I read that the Iyoto dishes easily.

OTOH, I have done some reading on various sword polishing sites including "3 Raven's Metalcraft" which has this in his blog:

What is Iyoto…

Iyoto stone comes from the area around Iyo in the Ehime Prefecture in Japan. Records show that iyomeshime has been used for polishing blades since the Nara Period, but there appears to be some anecdotal evidence that it was in use nearly 400 years earlier. (The Nara Period is around 700AD, so the recorded history of Iyoto stone spans over 1300 years!)
The mines were closed for a period of about 30 years in the last century, but were reopened and new material is slowly working into the marketplace.
Some varieties of Iyoto, of which there are several, were used as the final stone in sword polishing for about 500 years, until the Honyama mines around Kyoto became active. In the present day, and I hope someone will correct me if I’m wrong, Iyoto stones are part of the final series of stones foundation polishing (EDIT: looks like they might be part of the chu-nagura as well as the koma nagura).
Like all of the Japanese natural polishing stones, it is very difficult to pin down what the grit size is in order to give an accurate description of the material. The natural world didn’t provide uniform grains when these sedimentary rocks formed, unlike modern, manufactured stones that are composed of finely graded abrasives. In the case of Iyoto, the best that can be done is to provide a range of grit sizes that might be present in any given stone.
That being said, for comparison’s sake, Iyoto is somewhere between 800 grit (JIS) and 1500 grit.
The curve ball is that there are Iyoto that push into the 3000 range. For another trick pitch on top of the curve ball, that 3000 grit might come from the stone you bought as an 800 and have been using for the past few years.
The abrasive agent in Japanese water stones doesn’t break down uniformly, and the cementing particles in the lithic structure aren’t uniform either. Call it “The Miracle of Nature” or “God has a sense of humor,” but this is part of the reason why these stones are so wonderful and mysterious… You never know if the so-so rock you bought might not turn out to be the treasure of your collection as time goes on.
Many people who are familiar with synthetic or natural water stones know about the Nagura stone. It is a stone used to raise up the abrasive on fine grit water stones. It provides, with water, a thick “milk” on the surface of your stone that lubricates and polishes as you use it.
Iyoto can be used as Nagura, as well as for polishing blades. I have found that Iyoto (white and Arinoki) make a thicker paste than Nagura, and polish even better.
I just received a small shipment of Narutaki and Uchigumori stone, and I absolutely can’t wait to see what my Iyoto slurry stones will add to polishing with such fine grained stones!

I know this is kinda off topic, but anyone ever come across ANY natural bevel setter? Doesn't have to be Jnat. Was just curious if anyone found a decent one that would work for razors

Like a poster above, I am curious about the white amakusa...maybe it will work better than the red

Maybe when I get some money, I'll try it unless someone beats me to it

Nice quote on the source of Iyo stones or Iyoto. Iyo is on the island of Shikokyu near the town of Matsuyama, a beautiful town with tons of history and host (youtube it) of the Matsuyama mikoshi samuri battle festival. Matsuyama is also known for their porcelain ware. In the mountians behind Matsuyama and Iyo are the mines that produce the raw materials for porcelain, kaolin. The stratas of kaolin and those stratas producing material for Iyo sharpening stones are very similar and close together, not only in Iyo but in other areas too of Japan. This is why every once in a while you will hear of a chef who sharpens his knives on the back rims of porcelain dinner plates.

I'm getting surprising results from my Turkey stone, but am still to early in my experiments to say anything definitive. I will say this: their reputation for brittleness is earned. Mine is two inches thick and two inches wide. Of its four 6" x 2" surfaces, only one is crack-free.
