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.

Little Small On The Wrist
Really cool timepiece, been loving timex a lot recently, this is me coming over Casio/G-shocks. Although it is a bit smaller on the wrist it still looks very nice and I really love the gray and like green color contrast. Really easy to read the time as well.

Sturdy and digital
This watch has “ fake screws” holding the band on . The band is actually held on by the usual pins holding it on most watches but weaker . The pin came off while I was putting it on for the first time! This is the second time I bought off Amazon in 2 weeks where the watch appeared to be sturdy and the pins fell off . Going back to military watches that have material straps that go completely around wrist and do not have pressure on pins

Ten years of ownership…Thank you, Timex!
Color: Black, Size: One Size
Solid watch for everyday wear. I have worn this watch for over 10 years. I let a watch shop replace the battery about every 18 months. Other than the original band (which lasted 5 years) I have had zero problems. Still looks great, rugged and manly😇 Overall I recommend this watch for its value, reliability, simple clear design, legible hands in all light conditions. Great watch!!!

Solid Watch for Everyday Casual Wear
Color: Black, Size: One Size
I have purchased this item other times and I’m quite satisfied with wearing this watch everyday with casual wear. The size is just right not too small or large.
