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.

Sturdy and Easy to Move
Color: Black, Size: 132"- 6 Panel
This 6 ft black partition on wheels is exactly what I needed to divide space without sacrificing style or stability. It’s sleek, professional-looking, and blends in well with any environment—from office spaces to home studios. The build quality is impressive—very sturdy and doesn’t wobble at all once it’s in place. The wheels glide smoothly and lock securely, making it easy to reposition or keep stationary as needed. Assembly was quick and straightforward, with all parts clearly labeled. Overall, this partition is a perfect combination of functionality and design. Highly recommend it if you need a durable, mobile room divider that looks great and performs even better.

Nice once put together.
Color: Black, Size: 88"- 4 Panel
I really enjoyed these ones. They got put up, putting them together was a two-man task and not very easy at all. They work really good. They're very heavy duty. You can hang things on them. I kick mine out of the way and they work like a charm!

Sturdy, Easy to Set Up, and Looks Great
Color: Grey, Size: 34" - 3 Panel
I’m really happy with this RANTILA 3-panel room divider. It was simple to set up, stands securely on its own, and gives plenty of privacy. The height is perfect, and the panels look clean and modern in my space. It’s lightweight enough to move around but still feels sturdy. Overall, a great divider that works exactly as I needed.

Not 6 ft
Color: Grey, Size: 34" - 3 Panel
I bought this for filming my auditions. I am 5’4” .The height lists is 6 ft but the fabric only reaches 5’9 1/2 “! when I must film myself head to toe, the top bars are showing. It’s easy to set up. But when I film I must tilt my camera to keep the top bars out of frame which is not acceptable.
