Hutu sickle sword/axe

[sdmook]

First of all, hello!
My name is Sebastiaan Mook and I'm a small time collector of everything that looks cool to have.

I just bought a Hutu sickle sword/blade.
(the advert should be disappearing soon of the web, but it might still be there)



Its not this one, the handle is a little different, for the rest its identical.
The handle in my case if wrapped in rope.

What I would like to know, is the probable date of manufacture of these kind of weapons?
I have a hard time finding any good info about it on the web..

Kind regards,

Sebastiaan Mook
