Design of Barbarian Weapons

I have sketched 5 different versions of what my barbarians weapon could be like. Some have been inspired from the secondary images i gathered within my presentation whereas one was a weapon made of  bones. The bones have been gathered from many different creatures that the barbarian has scavenged from. This is a design that could seem rather ruthless looking. Sadly, I was not pleased with a weapon made solely off bones since it would not provide the amount of damage a metal weapon would bring. I then decided to use the design of bones and metal together.
