結論(まず簡単に)希少品。同じ物無し一点物

見た感じは 天然仕上げ砥石(合砥) の可能性がかなり高いです。
本職用として整形された仕上砥 に近いタイプです。
サイズは写真参照。

京都七条大宮の本職用砥石店で32年前に購入
今の時代よりずっと良い石が普通に売られていた頃です。
写真から分かる特徴

① 色と模様
乳白色〜淡いクリーム色
表面に赤い斑点(赤ピン)
片側に赤みが出ている
目はかなり細かい

これは京都天然仕上げ砥石でよくある特徴です。
京都の天然砥石は、仕上砥は特に
本山合砥
巣板
内曇
戸前

などに分類されます

中でも
白地+赤ピン=仕上げ砥としては上等寄りの石 です。

② 側面(層の出方)

側面を見ると
層が細かく詰まっている
気泡穴(巣穴)が少ない
表面がかなり緻密

京都の天然砥石は
「石英の微粒子が非常に細かく、2.5ミクロン以下」と説明されています

つまり
→ 粒度でいうと #8000〜#12000クラスの仕上げ砥に相当する可能性があります。

③ 形状と厚み

写真を見る限り
長さ:約15cm
厚み:約18mm前後
重量もそこそこありそう

このサイズは
昔の「本職用サイズ」に近いが少し小さめです。

現在の天然仕上げ砥石は、採掘量が激減しているため
この厚みはかなり貴重です。

種類の可能性(見た目からの推定)

一番可能性が高い順に並べると:

① 本山合砥(ほんやまあわせど)
プロ用の仕上げ用
大工・包丁職人が使う石

天然砥石専門サイトでも
「本山合砥は最も評価が高い仕上げ砥」 とされています



② 巣板系の仕上げ砥の場合
研ぎやすい
仕上がりが早い
木工刃物向き



性能(実際の使い心地の目安)

見た目から予想すると:
研ぎ味:やや硬め〜中硬
泥はあまり出ないタイプ
刃先はかなり鋭くなる
つまり
「切れ味重視の天然仕上げ砥」タイプです。
天然砥石の一点物になります。
写真でご判断ください、
又ご購入頂いた後の返品、返金は致しかねます。

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."

Please provide:
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.
