The Okada-giri
- The 太刀 銘吉房 (tachi, mei Yoshifusa), called 岡田切 (Okada-giri), is in the Tokyo National Museum. It was designated in 1949 under the old law and has been a National Treasure since 2 February 1955.
- Its name dates from 1584, during the Komaki and Nagakute campaign: Oda Nobukatsu used it to kill his retainer Okada Sukesaburō Shigetaka. The Japanese Wikipedia adds that he was accused of collusion with Hideyoshi.
- The sources consulted call it by that name, but do not give it as a meibutsu, and it has not been checked whether it is in the Kyōhō meibutsuchō (享保名物帳).
