Natural Stone Release
September 1, 2026 | 12:00 PM (JST)
（日本語文以下あり）

This time, the release will be at 12:00 PM (JST), two hours later than the previous release.

This release includes a larger selection of Ohira stones. Ohira is one of the stones we find particularly useful for knife polishing, and we have selected stones with finer grit and those that can produce a beautiful Kasumi finish.

One stone we especially recommend is Kizuyama.
It is a hard stone, and it has been a while since we last came across one. To be honest, it is not a stone for everyone.

However, it has very strong cutting speed and polishing power, we highly recommend it for edge sharpening and Kiridashi sharpening.

Every stone has been tested before being listed, and the results can be found on each product page. We have also uploaded videos of the stones, showing how they behave from a dry surface, how much water they require, and how much slurry they produce.

We hope this information will help you choose the right stone for your sharpening.

前回の販売に引き続き、9月も1日に天然砥石を販売します。
今回は12:00 PMからの販売です。前回と販売時間が異なりますので、ご注意ください。

今回は大平を多めにご用意しました。大平は包丁研ぎと相性が良く、細かい粒度や霞仕上げにおすすめのものもございます。

特におすすめしたいのが木津山です。
とても硬い石で、私たちも久しぶりに見つけることができました。
正直なところ、万人向けの石ではありません。
それでも非常に優れた研磨力があり、本刃付けや切出しの研ぎには特におすすめです。

今回販売する石もすべて面を整え、研ぎのテストも行っています。
各石の説明及び動画は、各商品ページからご確認いただけます。

Komon's natural stones are prepared and ready to use.

Each stone is carefully prepared before we offer it. The edges are rounded to prevent them from catching the blade and causing scratches during sharpening.

The surface is also flattened and conditioned with a medium-grit diamond plate, so the stone is ready to be used as soon as you receive it.
(Before each use, please clean the stone thoroughly, refreshing the surface and rounding the edges every time.)

Our next Natural Stone release will be on September 1 at 12:00 PM (JST). Details of the available stones will be posted on August 25.

Please note that the release time has changed from the previous release.

After the Kasumi finish

Kasumi Powder is made through our own blend and process, it does not contain coarse abrasive particles.
This allows you to create a beautiful Kasumi finish without introducing unwanted scratches to the blade.

However, the most important step is the foundation work before using Kasumi Powder.
We recommend preparing the blade to at least 1000 or more before applying Kasumi Powder.

The blade surface needs to be even, without uneven areas, and the sharpening lines should be consistent. For this, the blade must be properly straightened.
(If you need to correct blade distortion, we recommend our Knife Straightening Stick, Hizumitoribō!)

Where to apply the Kasumi finish.
(Before applying Kasumi Powder)

A Kasumi finish is created by polishing the soft iron (Jigane) of a knife, bringing out a beautiful cloudy/hazy white appearance that is characteristic of the traditional Sakai in Osaka finish.

When applying Kasumi Powder, it is important to consider which areas you want to refine and which areas you want to keep unchanged.
Before starting, carefully cover the areas where you do not want the Kasumi finish with electrical tape. In general, the area from the spine down to around the shinogi line is often covered.

By controlling the area of application, you can create a cleaner contrast between the polished Jigane and the remaining surface of the blade.

30/07/2026

Kasumi Powder restores a Kasumi finish by simply mixing it with water.

Add water to the powder in a separate container until it reaches a toothpaste-like consistency.

Protect any areas you do not want to polish with electrical tape, then gently apply the paste to the blade using the included abrasive sponge. Once you have reached the desired finish, rinse the blade thoroughly with water.

To spread the paste evenly, it is helpful to first place a few small dots of paste across the blade before working it in with the sponge.

Especially during the summer, the paste can dry out quickly.
If it does, lightly mist the blade with a spray bottle or add a small amount of water to the container as needed.
