【説明】
特別貴重刀剣に指定された、戦国時代初期・大永頃の備前刀工・祐定による傑作出来の無銘の刀になります。
昨年美術研磨に出しており状態も非常に良いです。

本作は無銘ながらも、与三左衛門尉が創始した腰開き
の互の目に蛙子風の丁子が交る、まさに与三左衛門尉
祐定そのものに伯仲する出来を表しており地鉄もよく積んでおり、戦国後期から増えた数打ちの出来ではありません。恐らくは与三左衛門尉祐定やその極めて近親の刀工による
大大名からの注文打ちの影打ちとして、無銘にされた上で世に流れたものと思料されます。
片手打ちの体配に強い反りがつき、前述の腰開きの互の目を焼いている事から恐らく時代は戦国初期の永正から大永にかけての時期と思われます。
この時期は馬上戦から徒歩戦へと戦の仕方が変化し、携行や抜き打ちに便利な手頃な長さの打刀が広く好まれ、祐定はその形状の刀の標本として扱われております。
特別貴重刀剣の鑑定書も付いており、もちろん刃切はなく状態も良いのでこのままでも十分にお楽しみいただけますが、与三左衛門尉祐定の名跡の付いた鑑定書を新たに狙ってみてもよいと思われます。
数打ちではない未備前、特に腰の開いた互の目を焼く祐定の刀は人気が高く、鑑定書も付いているとなると簡単に手に入る事はありません。この機会にぜひお求めください。

希望価格に大きく届かなかった場合取り消しを行うことがありますのでご了承を願います。

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.
