Natural Whetstones from the natural quarries of Kyoto,Japan are widely considered the pinnacle of sharpeners. This is a very fine grained finishing stone and are recommended for experienced sharpeners only. The natural quality of the stone means that the sharpening particles will be uneven and may not be consistent throughout. For this reason no guarantees can be given to the inner makeup of these stones. Furthermore each natural whetstone will slightly differ in size and condition, we highly encourage you to take a look at all the pictures before choosing a whetstone. These natural whetstones are assigned a series number (20-40), an identifying letter, and a grade from A-F based on their condition (size, weight, width, and any surface defects). Higher letter grades and higher numbers tend to be larger and wider stones that are mostly even across their surface and have minimal surface defects. Natural whetstones dish at a much slower rate than synthetic ones and therefore a good size stone can easily last a lifetime of use. These stones are essentially a lifetime investment.
