That’s actually how they are sold to maintain plausible deniability. Like how single roses in gas stations are sold in conveniently shaped glass containers. Or vape batteries being sold as “soldering irons” with a shitty soldering tip that doesn’t even work.

Point: it’s not a bottle opener. It’s a seatbelt bypass from the start. There are valid use cases for having one, like in a shop setting; but the average dudebro having one is a major red flag.
