This is the Saber (Shooting Knife) from the movie Blade Trinity. The grip is designed to print separately to the main frame for better esthetics and also for those who might want to print it in flexible materials. The main frame is hollow, the blade is detachable and the main frame also has a removable end cap for attaching a cord from it to the endof the blade for a more authentic look and for those who want to pose with it. The buttons are separate to the model for easier printing and painting.
On a side note for those who dont have high powered computers i recommend using the STL files rather than OBJ but if anyone has any issues when slicing let me know and ill be more than happy to cut the model up a bit more if required.
