A Water Stone for Curved Blades

Water Stones have become a favorite of sharpeners in search of the best edges. But previously, sharpeners working with curved edges like those found on pruning shears, florist's and grafting knives, and hawksbill knives have had to work mostly with flat stones, and anyone who has tried to sharpen a concave curve on a flat stone can attest to the difficulty that presents.

The Gouken Curved Water Stone neatly solves that problem. These stones feature a long, narrow shape with one edge shaped to a convex curvature, and another to a concave. Whether your knife, shears or carving tool has an inside or an outside curve, these water stones fit the bill.

Handy Size

At 5-1/4" (133mm) x 1-3/16" (30mm) x 3/4" (20mm), the Gouken Curved Water Stone fits comfortably in the hand, and will work with a wide variety of different blades.

3 Grits

The Gouken Curved Water Stones are available in three grits:

  • Coarse 220 - For fast sharpening
  • Medium 1000 - For lighter sharpening and refining after using a coarse stone
  • Fine 3000 - For finishing and maintaining sharp edges
Buy them individually, or get all three grits and save.

Care and Use

The Gouken Curved Water Stone should be soaked until saturated prior to use. Generally, this takes several minutes, but the exact time may vary. Look for a trail of bubbles when you submerge the stone. When the bubbles stop or significantly slow, the stone is saturated and ready to use. These stones should not be stored long term in water, and should be allowed to air dry between uses.

Made in Japan.

Received my Sharpening System today,(Norton IM83) and I've got to tell you that I am excited about using this product. I've been in the meat cutting business for 45 years, and as you can imagine, I've used allot of different types and styles of sharpening equipment. I have had 3 Norton Multi-Oil Stone units in my lifetime, and then I see this IM83 and I think that this is what I need to carry with me when and wherever I go. I just LOVE this little box full of expertise equipment to keep me sharp and at a razors edge. Thank you for the service, it was fast and easy, and I received it within 3 days of ordering. I know knives and how they work, and I can't wait to start putting that edge on my "other" knives I own.
