King stones are manufactured by Matsunaga in Osaka, Japan. They are the best known and oldest manufacturer of Japanese waterstones in the West. The King stones are soft and comfortable to sharpen with. You can actually feel and see the stone cutting the surface. The stones have to be resurfaced frequently because a hollow can quickly develop while you are using it. They also need to be re-flattened periodically because with use, they wear concave.
This King combination whetstone is made of 1000-grit on one side which sharpens and smoothes your knife, and 6000-grit on the other side to hone your knife. The dimensions of the stone are 7.25 by 2.5 by 1.0 inches. The stone will take away grinder marks and give you a nice polished edge. A plastic stand comes with this waterstone.
Several customers on Amazon said that you really don’t need the 6000-grit on this stone. According to reviews the lower grit does a great job of removing chips in the blade, and reprofiling knife edges. A carpenter, “Wood Wizard” says the waterstone produces mirror sharp edges that last a long time. Ralph Taliercio says that if the stones are used properly, they will give excellent razor sharp results. One customer suggested a small bottle be included for lubricating the stones. A professional chef noted that this knife is more for beginners because there is a noticeable difference in the slur that builds up. Another customer noted that these stones are not as effective on very dull knives. Amazon customers rated these stones 4.4 out of 5 stars.
