Chosera sharpening stones are used for sharpening knives on Edge Pro sharpeners. Chosera is a high-end series from Naniwa. Chosera stones are made of aluminum oxide. All Chosera stones are 6 mm thick and are mounted on high quality aluminum blanks.
Chosera series stones are universal, and can be used to sharpen knives of any steel.
Chosera stones should be used with one of these lubricant:
Chosera stones do not have any minor defects.
Chosera stones always have a color pattern. This is not a defect.
Chosera stones do not require any preparations. It's preliminary lapped.
Warnings. Do not soak Chosera stones in water. Just splash, or use a water spray. Never store Chosera stones in water. Never dry Chosera stones near heat.
Many end products are made by Gritomatic. We buy Chosera sharpening stones from international distributors, perform the cutting, flattening and lapping, and mount the stones to blanks. We keep the names of the original sharpening stones in the names of the finished products, as well as the countries of origin of these stones.
The first thing you should consider when combining stones from different brands is grit scale. Boride uses FEPA-F, while Chosera uses a different scale. Chosera 5000 is approximately equal to F 1200. That means that Chosera 2000 and 3000 will be a step down from Boride 1200. You should consider Chosera 10000 instead.
Yes and no. Chosera stones from 400 to 3000 grit use the JIS scale. Chosera 5000 and 10000 stones do not. Please see our grit chart for more information about conversions.
Buying 3 mm thick Chosera stones is not recommended. A thickness of 6 mm is becoming the community standard for Edge Pro sharpening stones. Additionally, 3 mm stones have a shorter life cycle and must be purchased more often than 6 mm stones, which is something to consider given the high price of Chosera series stones. Additionally, 3 mm thick Chosera stones are prone to sudden rifting when drying, making them unusable.
We don't sell sharpening stones without blanks.
