The NANIWA Super Stone (New Ceramics) series is a Japanese sharpening stone designed to deliver a smooth, “natural stone-like” sharpening feel while maintaining consistent synthetic performance.

Unlike conventional whetstones that feel scratchy or overly hard, this series provides a softer, more refined sharpening sensation that closely resembles traditional natural Japanese stones. This allows for controlled sharpening with minimal deep scratches on the blade surface.

The stone uses WA abrasive grains combined with a specially formulated bonding structure, which is the key to its unique “smooth sharpening feel.” Only a small amount of water is needed to start sharpening, making it easy and convenient to use.

It is suitable for a wide range of applications, from kitchen knives to woodworking tools such as chisels and plane blades. The fine grit options also make it ideal for high-level finishing work, including mirror polishing and aesthetic blade finishing.

Available in a wide grit range from coarse (#220) to ultra-fine (#10000), supporting everything from shaping to final polishing.

The series is available in two thickness options: 10 mm and 20 mm mounted stones with a plastic base.

A Huge Hit in My Bully Breed House!
Color: Green, Pattern Name: Hammerhead Shark
I have a house full of bully breeds, and this hammerhead shark toy is by far one of their favorites. I’ve actually bought a few of them so there are extras around the house — otherwise they’d all be fighting over the same one! That alone tells you how much they love it. The shape makes it easy for them to grab, chew, and toss around, and the squeaker keeps them interested without being obnoxiously loud. What really impressed me is the durability. My dogs are serious chewers, and we’ve had these for a while now. They’re still going strong, which is saying a lot in this house. The combination of rubber and nylon seems to hold up really well to heavy chewing. The bacon scent definitely helps keep their attention, and I like that I can add a little peanut butter for extra enrichment. It keeps them busy and off my furniture — always a win. If you have strong chewers, especially bully breeds, this one is absolutely worth picking up. Durable, fun, and clearly dog-approved in this house.

Finally a Toy My Aggressive Chewer Can’t Destroy
Color: Green, Pattern Name: Hammerhead Shark
My dog is an extremely aggressive chewer, and finding toys that last more than a few minutes has always been a challenge. Most toys are destroyed almost immediately, but this one has held up incredibly well. He chews on it constantly, and it still hasn’t been destroyed!

A Green Hard Plastic Sea Creature? Chew Toy
Color: Green, Pattern Name: Hammerhead Shark
This is a sturdy chew for my 40 lb retriever who is 9 months old. BUT after she has been chewing on it there are sharp edges which hurt my fingers when she wants me to throw it. It is strong and she enjoys it, so she can continue as long as she wants but, If it cuts her tongue or mouth it’s gone.
