Naniwa Chosera 1000 Grit Japanese Whetstone Sharpening Stone, NO stand/base, 20cmx7cm surface, 2cm thick
This semi-fine stone is used for prepping a final edge. This will smooth out the initially rough edge left by by a coarse stone or will return the burr for final finish with a fine 5000 grit stone.
Naniwa Professional 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 durable 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.
