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

[phooky@hexa.club]

@rootwyrm @futurebird seriously those things are super deadly

[phooky@hexa.club]

@letsbeworms @futurebird gotta work out the angles for your deer hunting mortar, which you calibrate with your tactical protractor

[westerninfidels@mefi.social]

@futurebird @vfrmedia *Tactical* ruler.

[eliterrell@mastodon.social]

@WesternInfidels @futurebird @vfrmedia Assault ruler.

[rootwyrm@weird.autos]

@phooky @futurebird and they're WAY more dangerous if you actually throw them instead of dropping them on your foot.

[mokhtarstork@zirk.us]

@futurebird It does resemble a knife.... Is there a sharp edge?

[futurebird@sauropods.win]

@MokhtarStork

The edge is blunt and it's rather thick.

@letsbeworms @futurebird

Never belittle the physics that has sprung from males in pickup trucks in the woods. If they need defense rulers to dress a moose, give 'em. Who knows what quantum hyperspace they'll do?

In Hi Skool, science teacher explained math of pulleys, blocks-and-tackle, etc. She asked JimmaJo how that might be useful. He said, "I guess if you're in the woods and your truck got stuck in mud, you could wrap a rope around a tree and use it to pull the truck out." True story!

[mokhtarstork@zirk.us]

@futurebird I understand, however, the handle creates the impression of a knife when its not.

[ottaross@mastodon.social]

@futurebird But will it protect effectively against someone with an offense protractor?

[kboyd@phpc.social]

@letsbeworms @futurebird ah yes the ford range

[asweetgentleman@mstdn.social]

@futurebird I can totally see that used for epic battles between Metric System supporters and Banana-for-scale System defenders.

@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.)

[moss@beige.party]

@eliterrell @WesternInfidels @futurebird @vfrmedia I remember in the 80s there was a Rambo-based trend for combat knives with “survival” tools built in like a saw blade, fishing kit, matches, etc. and many had a ruler printed on the blade and listed as a feature. Like wow in case of life-threatening emergency you can measure something up to five inches long!

@michael_w_busch @futurebird

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?

[michael_w_busch@mastodon.online]

@helplessduck @futurebird

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

[helplessduck@beige.party]

@michael_w_busch @futurebird

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.

[karaksindru@kind.social]

@futurebird somehow my first thought of an "attack ruler" is like a slide rule of some kind...

[terryhancock@realsocial.life]

@futurebird
Seems very similar to the "tactical umbrella" to me.
