A YouTube creator attempts to build a sword that can transform into a belt, inspired by a movie prop. Initially, he tries to create a complex mechanism using 3D printed parts and magnets, but this proves to be tedious and not very effective. He then simplifies his approach by using a flexible metal strip that can be bent into a sword shape, but still be flexible enough to wrap around a waist like a belt.
After experimenting with different materials and designs, he succeeds in creating a functional sword-belt that can be worn like a regular belt, but can be quickly drawn and used as a sword. The creator tests the sword-belt by cutting through various objects, including fruit and a soda bottle.
The video also includes a humorous montage of the creator using the sword-belt in a fictional fight scene, as well as a segment showcasing inventions sent in by viewers. The video is sponsored by Blinkist, a service that provides summaries of non-fiction books, which the creator finds useful for researching his projects.
