| Natural whetstones in Japan are all higher-quality ones, however they are
hard to get for ordinary users because of their expensiveness. Therefore,
we sell secondhand natural whetstones used by Japanese professional craftsmen
at popular prices. Japanese natural whetstones are divided into 3 main
types: rough/medium/finishing, though their types can't be judged before
sharpening them, so it is hard to sell them through internet. In addition,
it is impossible to sell exactly what users wish to buy unless the sellers
for them have some knowledge on cutting knives and natural whetstones.
That is why, we ask a 'KIYOTSUNA' craftsman who is a blacksmith having
an ancient and honorable origin as well as a owner of knife sharpener shop,
to sharpen knives actually using every natural whetstone and to judge the
type and quality. |

- The grain types of natural whetstones -
|
|
| Normally, Japanese natural whetstones are divided into 3 types, and further
here are subdivided into 6 types by breaking up the middle of each type. |
|
|
 |
|
rough whetstone |
| This type is used to sharpen chipped blades and to adjust their form. Suitable
for sharpening blades because of its rough grain type. |
| middle rough whetstone |
| This type is used to sharpen chipped blades and to adjust their form. Suitable
for making alteration of blades' form. |
| middle whetstone |
| Suitable for making alteration of the blades form and angle, as well for
fixing some chipped blades. Use after sharpening by a rough whetstone. |
| middle finishing whetstone |
| Suitable for making alteration of the blades form and angle, as well for
fixing some chipped blades. Easier to use than a middle whetstone. |
| finishing whetstone |
| Use for finishing to sharp blades. Absolutely essential for sharpening
kitchen knives to razors. |
| super finishing whetstone |

in Japan. |

| |
- Grades of natural whetstones -
|
|
| The grades were evaluated after the 'KIYOTSUNA' craftsman had sharpened
blades with considering the whole condition of our natural whetstones. |
|
|
|
| |
- The Hardness of natural whetstones -
|
|
| Using harder type of natural whetstones which produce less turbid water,
you need to sharpen blades after getting turbid water by rubbing together
with a whetstone called 'NAGURA'. |
|
|
|
| |
- The grinding surface of natural whetstones -
|
|
| Natural whetstones have sometimes bands or impurities in them. And we notice
the possibilities to be interacted by the damages when sharpening blades. |
|
|
|
|
| About Grinding Surface |
| When you use a natural whetstone, its grinding surface must be flat. But please note that the natural whetstones we sell don't have flat grinding surface. For those who are used to using natural whetstones, it is easy to make their grinding surface flat, though for novice users maybe a little difficult. Generally, making the surface of a finishing whetstone flat, we use a synthetic whetstone with grain type #1000, or for a middle whetstone, we do a synthetic one with grain type #100. |

| |
- How to source our natural whetstones -
|
|
| We have obtained the natural whetstones from shaving saloon owners who
have used and sharpened Japanese and Western razors. They were used by
professional craftsmen for years, so excellent quality and higher value. |
|
| |
- The origin of our natural whetstones -
|
|
| We speculate they were produced in the Kyoto area. |
