The NANIWA Nagura Dressing Stone “IRODORI” is a Japanese surface conditioning stone designed to enhance the performance of whetstones.

Unlike sharpening stones, Nagura stones are used to activate and condition the surface of a whetstone by generating fine abrasive slurry. This slurry improves sharpening efficiency, controls cutting speed, and helps achieve a smoother and more refined edge.

“IRODORI” is a synthetic Nagura stone developed to provide consistent and predictable performance, unlike natural Nagura stones which vary in grain structure. It produces a controlled slurry that can be adjusted depending on grit selection.

By using different grit levels of IRODORI, users can:

  • Accelerate sharpening speed with coarser Nagura
  • Reduce scratching and refine finish with finer Nagura
  • Clean and refresh clogged whetstone surfaces

It can also be lightly rubbed directly on blades or used to clean and maintain whetstone surfaces, making it a highly versatile sharpening accessory.

Available grit range: #220 to #12000 (multiple variations)

How to use
  1. Nagura Stone & Whetstone should be kept wet throughout the sharpening process by sprinkling with water,which acts as a lubricant on the stone.
  2. After setting Whetstone in  unmoved condition, rub the whetstone with Nagura stone equally(moving forward and backward) and wet stone power will appear soon, but do not wash or wipe off this residue and continue sharpening.
  3. Sharpen your knife as usual.

I found some of this years ago and loved it. Ran out, couldn't figure out where to find more then this last Christmas my mother gives me some of the rose salve and I remembered how much I loved the lotion. So as I was looking for more of the rose salve (also AMAZING) I got some of the lotion. It goes on really light feeling, but has some serious softening abilities. I use the salve on my knuckles first then use like a Chick-pea size amount of the lotion overnight and my hands are great the next day, especially considering how much I've been washing my hands and using hand sanitizer these last few weeks. It smells like lemon meringue pie, and is more lightly perfumed than BBB stuff (which I love since I'm prone to headaches). I love CO Bigelow products, have yet to try one I dislike. I use the overnight lip balm in the winter or during colds when my lips crack and dry the most. I use the rose salve for my regular daytime lip balm (stuff is the duct tape of the salve world, no joke!) and for extra relief on any dry skin. Some might argue it's a little expensive for the size you get, but you don't need much of any of them so they last forever. I still have half a tube of rose salve lip balm from Christmas and I use it every day, several times. They all smell good, they all feel really clean on, they do what they're supposed to without adding products (like glycerin) that will cause further dryness or chapping. Thank you so much, CO Bigelow for making so many quality products and being so consistent with the quality for so long. Fan for life here!
