View Full Version : More Jnats: 2 Asano Koma, 2 large Asano Botan, 1 Chu nagura

Five rare stones for sale. Details below.

These are all 'nagura' stones. People tend to think of nagura as slurry stones, and of course small nagura can be great for this, but that's not what is always meant by the term. Nagura can also be large koppa or full-sized and excellent for sharpening. 'Asano' nagura have a quality control system and are the most well-known, along with Tsushima nagura.

These are all great stones. Luckily I've got one more of each that I'm keeping.

First, here are all 5 together:

#1 above: Asano Koma (79g) sealed in cashew lacquer. $90 shipped to most countries

#2 above: Larger Asano Koma (132g). $135 shipped to most places

#3 above: Large koppa-sized Asano Botan (498g). Price $300 shipped to most places.

This one's quite special and an excellent bevel-setter for smaller knives. I got it from a big jnat collector who'd use it to set bevels on his razors. (His write up on this stone is here (http://www.tomonagura.com/mikawa-nagura/botan-nagura-koppa.html) and he's also got a video of it in use here (http://www.youtube.com/watch?v=lye8glRNETg).) Top quality Botan, and the price reflects what I paid.

(4) Top:

(4) Bottom:

4# above: An even larger koppa-sized Botan (670g). Price $280 shipped most places. This one also came recommended for its purity. Very fast natural, as Botan are supposed to be, and ideal for starting normal progressions with knives. For razors, I'm told these are the best natural bevel-setters.

5# above: Chu Nagura (1044g). Price $230 shipped to most places. This would be called koppa-sized, but it's big, wide and solid (145x90x43mm). Very uniform and clean layered stone. The corners have all been smoothed out and the whole stone feels very smooth.

This one is not Asano but, like the other stones above, the kanji describes it as a 'pure Mikawa white nagura'. Nagura like this look similar to Asano, but can be used differently. 'Chu' means middle and they were/are used mid-way through the sword polishing progression to erase scratches from previous coarser stones, so that the finishing stones after can do their thing. Use it that way, an ideal pre-polisher. However, you can also get a pretty nice, fine finish from it too.

Sorry, missed including a shot of (4) Bottom. This is for the larger Botan which has some skin on the underside:

A couple people have asked about grit ranges for these. The Botan, stones #3 and #4 above, might be around 1k-2k, or maybe even 3k as very white ones like these are supposed to be finer. The Chu Nagura, stone #5, is finer and would fit in well after an aoto for example, say in the 6k-8k range.

The small Koma, #1 above, is SPF. Thank you.

07-19-2014, 03:13 PM

Thanks, Jeffus. I'll PM you and then maybe you can reply.

07-30-2014, 07:11 PM
Jeffus - sorry, couldn't PM you. Maybe because you're a new member? I don't know how the PM rules go.
