Naniwa Professional (Chosera) Whetstone Sharpening Stone, 5000 grit

16 items left

Naniwa Chosera 5000 Grit Japanese Whetstone Sharpening Stone, NO stand/base, 20cmx7cm surface, 2cm thick. Made in Japan.

This very fine stone is just the ticket for finishing off your edge, or for regular maintenance. This is the smoothest most people will ever need to use, especially for German knives or any knife with standard steel.

Note: Naniwa has re-branded these as Chocera Pro (yes, changing the spelling to Chocera with a "c" now) for 2024. The stones are identical, just the branding/name and packaging has changed (again). You may receive the new or old packing as we receive and make the transition to new stock from the factory in Japan.

Naniwa Chocera stones are widely considered the finest stones money can buy. They are the next generation of the superb Chosera stones (which they replace), promising even faster cutting. They are artifical stones made with the magnesia bonding method. In terms of hardness they are slightly harder than the Super Stones, and because of the different bonding methods these "feel" harder and cut more quickly. They are very hard and long-lasting, but this extra hardness means that there is also more of a potential for cracking or chipping than with the Super Stones so be sure to air dry them and store in a cool, dry place and do NOT expose them to extremes of heat or cold (NO freezing!) or quick changes in temperature or humidity.

Do NOT soak them, and do NOT leave them soaking in water while you use other stones... in use, just splash more water on the stone as needed instead of prolonged and repeated soakings, otherwise hairline cracks can appear over time.

If you're not a regular user of your stones and only want them for occassional home use, we suggest that you consider the Super Stones or Traditional Stones instead, as they are still very high quality but are more forgiving of the cycle of wet/dry and extreme temperature and humidity changes in our climate. The Pro Stones fare better with regular use and regular lapping to avoid potential problems with cracks forming.

Warranty: 90-day warranty against manufacturing defects.

Good, true stones. The 1000 cut quickly and the 5000 polished well. In 30 minutes I sharpened 2 single bevel knives, each with micro-bevels, to shaving sharp. I am very pleased.
