Naniwa Diamond Whetstone Grit #600 DR-7506

I started my sharpening stone collection long time ago and have many Naniwa resin bonded diamond stones as well as splash n go ceramic stones. Excellent and reliable.Great feedback, even with the polishing grits, when sharpening quality hi carbon steel knives and tools.

This is perhaps my favorite of the 3 Naiwa diamond-in-resin stones I have. It cuts quickly, and can roll a consistent burr back and forth across an edge.(The 400 grit is great. Fast cutting on the verge of being a little harsh - but awesome, and weirdly still quite smooth. - The 3000 grit stone in this line is soft, milk-smooth & very effective.)I am comparing these stones to the older 'Pro' Naniwa ceramic water stones in 600, 1200 & 3000 grit. I like sharpening on the splash & go stones, but the resin stones are objectively faster, and I think many people would prefer them, if they didn't mind the price.

This stone is "feels" and sounds very different, in a good way. You don't feel the grit of the diamonds like my other stones, yet cuts even better with a finer scratch pattern. Doesn't make any sense, but you can see it in the results. It doesn't "feel" like the stone is doing anything, rather it feels almost smooth, especially for a 1000 grit. Yet when you look at the chisel or plane blade it is obvious that the cut is happening, and with a finer scratch pattern than my other two stones. Apparently, the resin bonding allows fresh diamonds to become available as the stone wears. Is it expensive, yes, but I feel that it will also last longer, and cut more consistently over a period of time. I plan on purchasing the other two diamond stones that Naniwa has to offer. If this one ever wears out, I'd buy another.

Nice stone but seemed finer than a 1K. Feed back was light but got the job done. Not as quick cutting as expected. Will try on ceramic knives in the near future. A little on the Pricey side. ( I am a big fan of Naniwa/Chosera stones)

This stone works extremely well and cuts harder steels with ease. I personally believe that this is fair priced for how well it works. Soapy water makes for extreme ease of use as well. Comes in an average size compared to many other stones. Would say that it is a bit heavier than ceramic stones but the weight really isn't compromising.

I sharpen knives everyday. it’s not my profession but I sharpen for myself, friends and family. This is the stone I use before moving to a finishing stone. If you don’t want or need a polished edge this stone would be great as the last stone in your sharpening progression. This stone cuts fast and leaves a beautifully consistent scratch pattern. You wouldn’t think it cuts as fast as it does by rubbing your fingers across it. The diamond resin coating is smooth and consistent. It loads faster than some other stones but cleans easily with a nylon brush and dish soap, and doesn't need flattening. It also comes with a dressing stone to remove any build up. I prefer to use the Naniwa flattening stone I purchased separately over the included dressing stone as that flattening stone is smoother than the included dressing stone and I think using the flattening stone will extend the life of this excellent stone.just use it, clean it occasionally and enjoy sharp edges. The technology used to make this stone is pretty incredible.If I had to pick one stone to sharpen with it would be this Naniwa 1K diamond resin. Gets the job done.

These stones are perfect. Important to read the manufacturer information. Also do some research. The best stone is nothing more than a rock in a fools hand.

I like the nice finish and the weight of it stays what you put it when using on A non-Slip surface Quality product
