Interesting, this duality male/female in African weapons.
Another exemple with these Laka throwing knives called miya-bo, the nga-til is the male one, and the ngéégue the female :

"The King, Mbang is the guardian of the trowing knives, and without the autority of miya-bo he would have to resign the office.Once a year, at the rain-making festivals, the Mbang displays the miya-bo to the people.At other time of the year the throwing knives are kept in a special hut, the ngéégue, facing the setting sun, nga-til looking towards the dawn.This is also the way in which the bodies of Sara Daye men and women are placed when they are buried"
from "African Arms & Armour" C.Spring
I agree with the fact that the nature inspired the creator of the weapons, especially, just look at the different shape : leaves, branch...women !
Abstract or figurative like my avatar wich is sometimes describe as "the representation of a human being with raised arms, some see it even as the representation of female sexual organs, provided you hold the blade in an abnormal position, upside down." from "Tribal arms monographs vol I / N°2.
But maybe this is the product of a delirious mind of an european...
Do you know other exemple of male/female weapons, not especially African ?
