Broken Bow (3.5e Equipment)
From D&D Wiki
A broken bow is just what it sounds like: a bow With one of its limbs broken; ideally a long bow is broken with its sides at a 2:3 ratio, and a short bow at a 1:1 ratio. A short bow is 1/3 the weight of a longbow.
A broken bow is a double weapon. You can fight with it as if fighting with two weapons, but if you do, you incur all the normal attack penalties associated with fighting with two weapons; the shorter end of the bow is treated as a light weapon for purposes of attack modifiers, and as one size smaller for damage purposes. If it is a short bow, then both ends are treated as the smaller end. if it is a long bow and both sides are the same, both are treated as the larger side. At fine the smaller end deals 1d2-1 damage.
If a broken bow is wielded one-handed, it is treated as a reach weapon; treat the side that makes contact as the side you are attacking with. Switching sides of the broken bow is a move-equivalent action.
A broken bow may be used as a garotte, and may be used to make trip attacks.
