Sci-Fi Fantasy Bow (OC Concept & 3D Model)

A bow for my character of a sci-fi book. (Was part of a uni project in 2022, where we had to model an object of our choice (based on our concept design). We also had to go into groups and each group got a theme. My group had museum as its theme.)
The bow may look like it's a simple bow used in the Middle Ages, but it is actually high technology. It can fold in, so only the handle is visible. And that handle can camouflage with the environment or make itself look uninteresting (i.e., should someone put it into a museum, it'd look rusty and useless).
