Here's my take for all of the swords:
- So, if you chose the synonym sword, I couldn't probably just erase the words off paper. Then I'd know what you was saying. And this sword wouldn't be hard discarding when you want to speak from someone verbally. Without that being heard, that sword isn't a no-stop.*
- With the safety cone sword, this one would be very problematic to wield when out in public. At first, you're seeing things with your usual sight, and then suddenly your POV changes to someone else's. And there are probably gonna be a lot of people looking at you like "Why is that person carrying that strange sword?", causing you to see multiple POVs conflicting with each other, all while you either stop moving or keep moving, putting you at risk of bumping into stuff. I wouldn't wanna wield that sword...
- I think the advanced smelling sword is the safest one. You could just breathe through your mouth when you don't want to smell bad stuff. But it's also useful for stopping or escaping a disaster, like a house fire or a gas leak. With that in mind, I'd choose that sword.
*If you understood the joke give yourself a pat on the back LOL
