刃物の切味がすばらしい夢のトイシ 

ダイヤモンド砥石は砥粒が硬く、ほぼ擦り減らないので、砥石のような減りがほとんどなく常に平面精度を保ちます。

高い研磨力。使用されている素材がダイヤモンドの砥粒を使用しています。

ダイヤモンドは硬さがあることから、ひとつひとつの砥粒が硬く鋭くなっており、そして砥粒が表面に突き出しています。

そのため研削性がとても高く、良く研げるのもダイヤモンド砥石も特徴です。

焼結はダイヤモンド砥粒と結合材を高温高圧で焼き固めて作ったものです。

焼結は層を厚く作ることが出来るので、電着とは異なり寿命が長く安定して使用することが出来ます。

番手も荒砥石から仕上げ砥石まで幅広く種類があるのが特徴で、研磨力は電着には若干劣りますが、その分研ぎ傷が浅くなり次の砥石の傷消しが楽になります。

平面保持力も高いので、仕上げ砥石でしたら和包丁の裏押しなどにも最適です。

反面電着と比べて製造コストが高いので価格も高価なものが多く、層の厚みも影響して少し砥石減りがあるのと、目詰まりがあるので面直しが必要になる事があります。

メリット
層が厚く、電着よりも寿命が長く安定して使用出来る。
荒砥石から仕上げ砥石まで幅広く番手があり、研ぎ傷も電着よりも浅くなる。

デメリット
製造コストが高いので、価格が高価になりやすい。

ダイヤモンド砥石に合った使い方

切り刃のベタ研ぎ: ダイヤモンド砥石に合った研ぎ方は平面に刃を研ぐ、いわゆるベタ研ぎです。

ダイヤモンド砥石の特徴は硬く常に平面であることと、高い研磨力です。

そして研ぐ刃もとても硬いのですが、これはお互い硬い物同士で研ぐことになります。

そのためダイヤモンド砥石で研ぐ場合は、お互いが点と点で研ぐので接地面はとても狭くなります。

これを研ぎ続けていきますと、点と点が広がっていき切り刃が平面のベタ研ぎとなります。

包丁はハマグリ刃にすることが理想ですが、ハマグリ刃に研ぎ続けていくと稀に刃が丸刃になって厚みが出るときがあります。

この時にダイヤモンド砥石で切り刃の厚みを整えることが出来ます。

また鉋やノミなどの大工道具は常にベタ研ぎの刃ですので、これらにもダイヤモンド砥石は向いています。
和包丁の裏押し
包丁には必ずベタ研ぎをしてもらう包丁があります。

それが和包丁の裏押しです。

裏押しをする時は必ず砥石を平面にしておく必要がありますが、平面維持力が高く、常に平面な状態のダイヤモンド砥石は裏押しには最適の砥石の一つだと思います。
砥石の面直し
意外かもしれませんがダイヤモンド砥石は面直しに最適なものです。

面直し用の砥石もありますが、これも面直しに使用すれば砥石と同じように減っていきます。

均等に減っていけばいいのですが、どうしても砥石と同じように片減りしてしまいます。

ですが、ダイヤモンド砥石はさんざん説明しています通り、常に平面な状態ですのでダイヤモンド砥石で面直しをすると砥石の平面の精度もとても高くなります。

International Shipping Methods
Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao.my and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters). After sending the email, notify us in the customer service message. We will confirm with the seller as soon as possible. and if there are any related questions, we will contact you through the customer service message. Thank you for your cooperation."

1. "Product ID"
2. Photo of the "Delivery Note" (if any)
3. Photos of the outer box (including inner and outer packaging)
4. Photos of the product (Please include relevant descriptions to help us confirm with the seller)

Important Notes:
1. Do not include foreign text or other products in the background of the image.
2. Please keep the complete product packaging (including the shipping label information), and refrain from repairing or altering the original condition on your own, as any changes may result in the case being unable to be processed.
3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
3. Transport Damage: If the goods are damaged during international shipping (to the pickup point), you need to provide photos of the outer packaging of the parcel and clear photos of the damaged goods' outer packaging.
