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 (https://www.printables.com/model/350089-anduril-thin-model-for-wall-mount), but I added the black grip and forged the blade-handle union.
