Ethnographic Arms & Armour - cast lady bamboo cane sword

Newbie here. Recently inherited a lovely piece that I was completely unaware of, it came with a hand carved short wooden riding crop that GGgrandfather carved for GGgrandmother. It appears to be cast lead (soft heavy, but the blade might increase weight) top with a small brass "button" to release an ornate blade both carved out and embossed. The bamboo cane is common, you can see wear on the area one might hold it 3/4 way up. The cast female figure is just head and shoulders, but nicely detailed. She has a somewhat flattened nose and some embossed detail is either worn or broken off and a lot of dents scrapes which suggests somewhat heavy use. The blade has some rust but beautiful detail, notches, and embossed details. You can see it was cast between hair and ribbon where there is no wear, hmmmm that might be suspicious if the piece is intentionally worn. It will need some workk on the button as it is worn and can slip out of place, (where does one go to get that "fixed". A very feminine weapon so of course I love it and cannot wait to see if someone has seen something similar in their travels. I am in Canada, but family lineage is French and Scottish if that helps.
