Toyotomi Hidetsugu
This is one of the few blades signed by Masamune that is not in question as to the signature. It was bought by Toyotomi Hidetsugu in 1601 for 500 Kan and was passed to Shōgun Ieyasu and from him to Maeda Toshiie. Maeda Toshitsune presented it again to the shōgun, possibly on his retirement. Later, the sword was handed down among the Owari Tokugawa. This blade is a tantō (dagger) approximately 25 cm (8 sun 6.5 bun) with a carving of roots on the "omote" (front, outer edge) side. It also has chopstick-like grooves (g"omabashi" 護摩箸) on the back and a dragon at the "ura" part of blade ("kurikara" 倶利伽羅). The blade features an engraving of Fudō Myō-ō, the buddhist deity which gives this blade its name.
