Two-bladed sword

A two-bladed sword is an exotic, two-handed melee weapon that can be used as a double weapon.

Description
The two-bladed sword is approximately the same length as a greatsword or a quarterstaff but has two short sword-sized blades at either end. The whole thing is one piece of metal but instead of a hilt the two blades share an elongated tang in the middle. This tang is usually wrapped in leather or leather-bound wood for a comfortable and versatile grip. An average two-bladed sword costs 100gp and weighs 10lbs (4.5kg).

Weaponology
It takes special training to wield a two-bladed sword effectively, therefore it is classified as an exotic weapon. The two-bladed sword is a double weapon that can be used for two-weapon fighting and must be wielded two-handed if so.
