大型で質の良い、ほぼ未使用の希少な天然改正砥石を出品いたします。

こちらは25年以上前、京都の歴史ある砥石屋さんで購入した正真正銘、本物の天然改正砥石です。
改正砥石の鉱脈は新潟と山形の県境にあり、青系の砥石と茶系(赤系)あるいはその中間色がありますが、今回出品するのはどちらかというと茶系に近いものです。

改正砥の鉱脈の入り口は、山形新幹線を建設する際に埋められてしまったそうで、廃坑から半世紀以上経過しており、今後新たに採掘することが出来ない希少な品です。

改正砥石は古くから刀剣研磨に使われ、天草砥石(主に備水)で付いた傷を素早く取り去る目的で使われています。
このまま刀剣研磨用としてお使い頂けますし、もちろん、包丁や鑿・鉋用としてもご使用頂けます。
包丁では仕上げ用、鑿・鉋では中砥石としてお使いください

長さ:233mm 幅:64mm 厚さ:85mm 重さ:2.71㎏

写真は井上藤助の日本剃刀を、名倉無しで数回軽く研いでみたものです(剃刀は付属しません)。
すぐに黒い研ぎ汁がもくもくと出て来て、気持ちよく研ぐことが出来ます。

写真にあります通りわずかなヒビが入っていますが、使用にはほとんど影響ありません。

欠点の少ない改正砥石が市場に出回ることは、非常に少なくなりました。
非常に質が高く、今後入手できる機会は少ないと思います。
 
個人保管の中古美品ですが、試し研ぎをしたのみで実際には使用していません。
 
天然砥石の特性として、人工砥石ほど使いやすいわけではありません。
この砥石はかなり使いやすい部類ですが、まったくの初心者の方や天然砥石にあまり慣れておられない方にはお勧めいたしません。
研いだ感想などはあくまでも私の主観ですので、ご了承ください。

残念ながら近年、手元および目元が不如意になって参りましたため、少しずつ長年のコレクションを手放してまいります。
手元に残したい一本ではありますが、使って頂ける方にお譲りすることにしました。

天然砥石の性質や特性をご理解の上、ノークレーム・ノーリータンでお願いいたします。

なお出張等で不在にすることが多いため、お支払いのタイミングによっては発送まで一週間程度、日数を頂く可能性があります。
またお盆期間(8月9日から16日まで)は発送が出来ませんので、あらかじめご承知おきください。

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.
