They can be duel-wielded, but they can't be duel-reloaded. They have the loading property, and it takes two hands to load. So....fire your bows, but then you have to put one down/away to load.

My favorite bit of weapon flavor I did was a character that grew up in a town that had been historically plagued by vampires. The whole culture of the area was about fighting vamps, and the favored weapon was a morning star (which traditionally have a wooden handle). These guys would hide a stake under a pommel attachment. Fight with the morning star like normal, but if need be, the bottom could be taken off for a wooden stake.
