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.

Easy to assemble. Still used for over a year 🙌🏾
Color: White, Size: 6 Panel
Everything is perfect! I would buy again in other colors and heights if I need additional separation in the basement.

Cheap Garbage
Color: Black, Size: 4 Panel
This item is just cheap crap. Shoddily put together, shoddy materials, and looks cheap. If you’re just putting it in a space that you don’t really care that it’s cheap, then it might be fine for what you need. But don’t expect much.

Keeps areas separated
Color: Black, Size: 6 Panel
Item arrived quickly. I use this to keep my cats out of a part of the cellar. Works great. They've figured out how to slip through side. I made a panel that covers those spots. Still the best item to keep area separate.

Worth the investment
Size: 1 Panel, Size: 1 Panel
I had to order this in an emergency. To put it in brief words, I live in a two level studio unit. My bedroom TV fell backwards off the bureau accidentally and down the stairs to its demise. Putting this together was no problem, instructions were thorough and easy. It came with several bars that connected together smoothly and an Allen key for the brackets and screws for the feet. I did one less horizontal bar on top and bottom so it could fit, which was great because with all of them on it was too long. However I ran into the difficulty of the horizontal bars popping out of the brackets during the last stages, but eventually got it done. I was also looking for a specific type of divider where I could adjust the feet so I could tuck it in between the dresser and banister. Glad I made this purchase.
