Sword 3 is an unidentified blade most likely of Chinese origin. The sword has a small removeable dagger hidden at the base of the handle. The combined length is just over 43 inches. The dagger is 10 inches in length when removed (blade and handle). The sword material appears to be damascus steel. There is a visible rippling effect throughout the entire blade. I believe the handle for both the sword and the dagger are bamboo. The sheath is made of the same material, with a metal interior. The primary blade has inscriptions at the base of each side of the blade. One side says two things, the first part says “momokawa” (百川) which is the name of an old rakugo play. The second part might be “morihito” (守仁), a first name probably (though not a common one). We could possibly be looking for a smith called Morihito Momokawa? I only recognize two characters on it, 正 (translates to "correct"/"right") and 二 (translates to "two") (it’s upside down in the pic). I'm not certain on their combined meaning. The inscription is of Chinese origin but is also used in Japan. The dagger is made of a different metal from the primary blade. It is soft, light, and flexible. There is heavy rust/tarnish present on the dagger.

My father owned it. I inherited the blade after his passing
