This is a custom bow that should be able to slpit into two scimitars.
I came to this idea while reading a book by R. A. Salvatore.
In this book the main character (Drizzt Do'Urden, if you don't know him, please google him) constantly switches between bow and scimitar while his companion, an elven woman named Dahlia, has an eight feet bo staff that can turn into two four feet combat sticks, a tri-staff and two "exotic" flails (because saying "nunchucks" in D%D is still weird).
Now, while Dahlia's weapon is kinda dumb, the idea of a multi weapon seems intresting.
