It's simple, versatile, and easy to design/mold.

Or try to make it appear more modern, such as these:

It all depends on who you are trying to appeal, the traditional Kamas would work very well in a set or wave of ninja styled

the infamous nunchaka.
The advantage of the more modern Kama is that they would blend in more with other of Will's Creations. Such as the tactical
sword, which has a resemblance to the ninjato, a straight-bladed ninja sword.
