The Naniwa Chosera 10000 (10k) whetstone uses magnesia as binder for the abrasive, in this case white aluminium oxide.
The Chosera stones do not soak up any water so the stones do not need to be sprinkled with water frequently. This makes Chosera stones rather easy to sharpen with. Because of their hardness you will not cut into the stone easily and sharpening with these stones will take less time. Their hardness make them a good choice for knives made from hard steel.

Splash with water before and during sharpening, do not soak or store in water.

Grit: 10000

Measurements: 210 X 70 X 30 mm

Comes with anti slip towel

About grit sizes
Whetstones come in various grit sizes. The higher the number, the finer the grit. A finer grit results in a sharper knife. Sharpening a really dull knife on a fine grit will take much time, so you will need to treat it on a coarser grit first.

120 - 600: Appropriate when real dull knives need to be brought back in the right shape
800 - 1,000: Appropriate to sharpen knives that were already in a reasonable state
2,000 - 3,000: For a result sharper than most knives are when they leave the factory
5,000 - 12,000: To polish the knife and get a razor sharp edge

Remarks pertaining to Chosera sharpening stones
During manufacture, Chosera sharpening stones are bound with magnesium. This superior production method guarantees superb results. However, these magnesium-bound stones are more prone to developing hairline cracks. To prevent this from occurring, it is important NOT to use too much water when wetting Chosera sharpening stones. So Chosera stones should NEVER be left to soak in water for a prolonged period of time! It is also important to dry these stones thoroughly after use and store them in a dry, dark place.

It is an expensive stone but it really works very well. Polishing is what you do, not sharpening! This is the crème de la crème product among sharpeners!

This is a top product. For the production of this is the bar very high. And we all know that in the high-end product for each region for a few percent more performance-digit percentages to be paid more. A variant of the law of diminishing returns. Do you want the top 10% more performance than you pay 100% more willy-nilly. Therefore, despite the high cost of the stone for the P / K ratio also October 1

Review from www.knivesandtools.nl. For your convenience translated into English by Google Translate.
I primarily bought this stone for my razors. I have been only a few of King's 8000 (also synthetic Japanese water stone), but this thing is much better (and "only" five times as expensive ...). The razor is sharper than on 8000 pieces, but it also goes much faster and easier. Great for razors so. I sometimes use a Chosera 5000 and 3000 for grinding. My chef's knife I t / m the Chosera 5000, and I got him for the hell ever done this 10000. Is indeed very sharp (see the youtube videos of knives and tools), but I think I will not often do. Because there is no foot in it is a strange duck in the bite when the rest of the series Chosera doing, and that's what impractical. I also like the stone as nice as possible for the razors, knives for cooks and I am satisfied with the 5000-sharpness. Stone is quite expensive I must say, but as I said it actually performs much better than the cheaper 8000 stone that I had (both razors and chef's knives).

Fine stone. Together with other chosera stones (400-800 - 3000 - 5000) Reach me (after some practice) a very good result. Razor Sharp. Be careful that the retention angle, otherwise the knife bites into the stone. In chosera stone that chance is not very large. He is hard enough.
I think he's not cheap compared to other stones.
I do not know what's the reason was.
Very good service, you will soon rock the house. I have had a telephone conversation with knives and tools, what struck me was the friendliness and honest advice. Big compliment.
