This is Anduril from Lord of the Rings. This is designed as a desktop toy - something to play with when sitting at your computer and needing distraction. It's designed to print in one piece. The handle and main blade section are drawn from someone else's model, but I added the black grip and forged the blade-handle union.
The author remixed this model.
I used the handle and main part of the blade of the original weapon, shrunk it down, and then repaired the grip and handle as the smaller sizing created defects in the model. I added a black grip to the handle and modelled as a single print desktop toy.
