What in the name of EDC nonsense is a "defense ruler" ?

UPDATE: Clearly I need to show ya'll some photos of this nonsense

The one time I encountered such a thing, it was very obviously "I am going to pretend that this is not a blunt sword".

The handle was the giveaway.

@michael_w_busch

why not just have a blunt sword?

@futurebird

I am guessing that this is a way to try to get around rules about concealed weapons.

(When I was training in kendo; we had to be careful to not violate those rules when carrying blunt training blades in gym bags.)

I've never bought a pair of brass knuckles in my life, but I have bought a few paperweights that looked remarkably similar in form and were made of brass.
I wonder if that's what's happening here?

@helplessduck @futurebird

There is similar rules-skirting with "high power narrow beam flashlights" that are very obviously actually dangerously bright laser pointers.

I carry something that is very obviously a club in my car. It's a miniature bat, and I absolutely can't carry that around with me on the street. After some cursory searching, I'm questioning whether having it in my car is even legal in North Carolina.
