I make and sell real life, 3D replicas of daggers from video games, TV, and movies. Currently I am using the original names of the daggers to sell my products (and I am aware that I am likely infringing on intellectual property). However, if I rename the weapons to more generic names to sell them under as opposed to their in game names, would this still be copyright infringement? My main concern is that the appearance is still the same as it is in the game. Is it likely to get me into legal trouble?
