In most CRPGs, the weapons are too fantastic and don't have any real life counterpart, or they are very common types of weapons and mostly derived from Medieval - Renaissance European weapons.
In this thread I would recommend posting some suggestions regarding exotic weapons from real life which can be included in the game.
My first suggestion would be the "Yatagan" sword. It is a short sabre which was extensively used in the Ottoman Empire territory between 16th - 19th centuries. It was the trademark sword of Jannissaries. The originality of this sword comes from the fact that it is curved towards the front and has no hand guards at the hilt. It was ideal for carrying as a side arm next to the musket, due to its small size and strong slashing momentum because of having its center of weight towards the tip.
The yatagan was worn on the waist inside the sash, slightly similar how the samurai used to wear the wakizashi. (On this photo M. Kemal Ataturk posing as a Janissary)
