Model of a sword from the anime "Attack on Titan". This is a functional sword. All buttons and lever are pressed. The blade is fixed inside and pulled out with the trigger. The demo clip briefly shows the assembly process.
For assembly, 4 springs of different formats, 6 bolts with nuts, one sleeve for the trigger and an aluminum flat sleeve for the blade (shown in the photo and video) will be required. But you can pick up all additional details at your discretion.
