Translation help on a WWII sword

[captainsimos]

My son inherited this sword from his father in law and there is writing on the wooden sheath I was hoping someone can translate. Sorry for the poor quality of the pictures. Thank you in advance.

I'll try to darken the writing up a bit.

長谷川ーHasegawa
貫一-Kanichi

This is probably somebody's name.

PIC 3

奥澤町三‐三二 ‐ Okusawa Machi 3-32

This is an address, probably the owners or stores or whoever's it was.

The picture is upside-down.
長谷川貫一 Hasegawa Kan'ichi (a person's name)
奥沢町 Okusawa machi (a place name. There is an Okusawa district in Tokyo's Setagaya ward for instance. May be any other Okusawa though)
三・三二 3/32 (some number, perhaps an address in Okusawa)
