Many of the other no touching tools do not have any type of enclosure which we will touch it with our hands or clothes eventually. Even those with an enclosure, it is a separate enclosure so it is not as convenient. This design is inspired by the army knife design where you could pull the hook out and store it without a separate enclosure!

Another main point of my design is that it would lock in place when opened or closed so it would not accidentally wobble or slide out of place. (There is a slight click when fully opened and closed, which is a bit satisfying, but don't fidget with it after using it in public!)

It could also act as a keychain or just put it in your pocket when going out.

This is the updated version with a thumb hook added to improve accessibility and hygiene as one does not need to be near the contaminated hook. It could now also be opened with one hand! Thanks to some kind people in the internet for their advice. (@dr.dentz and @mikeholczer)
