With the current ones, you have 3 modes, basically.
- Just the hilt (with the blade removed. just push and twist and it’ll come out). I think they sell belt clips so you can carry it around this way.
- The hilt plus the blade, but unlit.
- Hilt plus lit blade. There’s just a little switch on the side. When it’s lit, it acts like a real lightsaber - with all the appropriate sounds when you come in contact with something.
