I recently gifted my girlfriend a tachi sword, which she absolutely loved. She's a big fan of Japanese series, especially ones like Rurouni Kenshin, so the sword perfectly fits her interests. It was such a unique surprise, and she appreciated how it tied into her hobbies.
If your girlfriend enjoys Japanese culture or historical pieces, a tachi sword might be an exciting gift. It's not something you see every day, and it could be a meaningful addition to her collection. I found some
tachi sword for sale for those interested, at a very good price.
