Local student arrested for 'manufacturing weapons.' In reality, he printed some PLA shivs that would probably shatter if they hit a piece of parmesan cheese. The police seized the printer like it was a meth lab. 10/10 for the dramatic crime scene photo, though.

(Backstory: a few weeks ago a student in another city/school was stabbed with a (iron) knife and died so now politicians need to show that zero tolerance policies are successful.)

But they didn't confiscate his kitchen knives?

[–] RagingRobot@lemmy.world 13 points 1 day ago (1 children)

Those probably have serial numbers and a whole tracking system lol

[–] pineapplelover@lemmy.dbzer0.com 2 points 14 hours ago

Did they take away his rocks too?

[–] entwine@programming.dev 75 points 1 day ago (4 children)

I don't get it, are knives illegal in Italy? What if I want to cut my spaghetti?

[–] NaibofTabr 85 points 1 day ago

What if I want to cut my spaghetti?

[–] squaresinger@lemmy.world 70 points 1 day ago (2 children)

This is the really weird thing. If these knives were made of metal and in a kitchen drawer, nobody would think of them as being weapons. But since they are 3d printed, that's novel enough to warrant some panic or something...

[–] ExcessShiv@lemmy.dbzer0.com 10 points 1 day ago (1 children)

Not sure how rules are in Italy, but where I live "switchblades" and other one-hand operated collapsible knives are illegal.

[–] Jocarnail@lemmy.world 9 points 1 day ago (1 children)

Afaik, all single hand operation deployment knives are illegal in Italy. It's somewhat of a nonsensical rule when there are teenagers stabbing themselves with kitchen knives, but still...

[–] ExcessShiv@lemmy.dbzer0.com 4 points 1 day ago* (last edited 1 day ago) (1 children)

You can make surprisingly sharp objects, I once cut myself with my printed bed-scraper by accident.

These printed knives can absolutely also be used to hurt/kill someone, if you wanted to...like all type of knives and basic cutlery really...these being an illegal type is the trigger here I believe.

[–] Jocarnail@lemmy.world 1 points 1 day ago

Of course, I never intended to imply that a plastic knife would not be dangerous

[–] Jocarnail@lemmy.world 7 points 1 day ago

It's not because they are 3d printed. He was distributing them at school! That is the problem.

If he were to file down toothbrushes and do the same he would still be arrested and his files confiscated.

[–] JohnEdwa@sopuli.xyz 20 points 1 day ago* (last edited 1 day ago) (4 children)

Spring assisted switchblades are illegal in quite a few countries, so I imagine they are in Italy as well. Still completely ridiculous, as these are plastic toy replicas, and not actual knives.

[–] teft@piefed.social 5 points 1 day ago (2 children)

Often even unassisted switchblades are illegal. They're called gravity knives.

[–] FuglyDuck@lemmy.world 14 points 1 day ago (3 children)

Just to be pedantic, gravity knives aren’t switchblades.

They have a blade that slides freely (and under the force of gravity.) the grip is basically a hinged nutcracker that, when closed, traps the sliding blade either deployed or retracted.

In any case, they’re no more dangerous than your standard folding knives of the same general proportions.

The illegality of certain knives (switch blades, gravity knives, balisongs, etc) are largely not based on the danger or actual use of those knives as weapons.

In the US it’s usually reactionary and racism.

[–] teft@piefed.social 2 points 1 day ago (1 children)

Gravity knives are considered switchblades in many jurisdictions.They aren't spring assisted switchblades. They are gravity assisted hence the name. Switchblade just means any knife you open with a switch or button. Don't take my word for it though, go read the first line of the wikipedia page on switchblades.

In any case, they’re no more dangerous than your standard folding knives of the same general proportions.

Often they are less dangerous since they can fail to deploy (especially an OTF spring assisted switchblade). I had a sweet benchmade switchblade when I was in the army but alas it got lost at some point. That knife was the best for one handed box cutting.

[–] FuglyDuck@lemmy.world 5 points 1 day ago (1 children)

maybe instead go to the wikipedia page for 'Gravity Knife'

or just read my comment more fully. Gravity knives don't have switches. or buttons. If you're considering the hinge mechanism that allows a gravity knife to operate, then practically any folder is a "switch blade" and that's just not true.

from the wiki I linked:

A gravity knife is a knife with a blade contained in its handle, which opens its blade through the force of gravity. This mechanism of opening is fundamentally different from the switchblade...

Even in gravity knives that appear to be opened by a switch or buttons... all that button is doing is unlocking the blade to allow it to be deployed or retracted. If simply having a button or switch or something is all it takes to be a switchblade, then this classic gem would also be a switchblade.

[–] teft@piefed.social 2 points 1 day ago* (last edited 1 day ago) (1 children)

https://en.wikipedia.org/wiki/Switchblade

A switchblade (also known as switch knife, automatic knife, pushbutton knife, ejector knife, flick knife, gravity knife, flick blade, or spring knife)

Like I said, many jurisdictions consider gravity knives to be switchblades.

[–] FuglyDuck@lemmy.world 2 points 1 day ago (1 children)

and many jurisdictions have laws written by people who don't have a frooking clue and are simply reacting to a knife being associated with whatever out-group happens to exist at the time.

[–] teft@piefed.social 3 points 1 day ago

What does that have to do with the price of tea in china?

My original comment said gravity knives are considered switchblades in many jurisdictions. Politicians being morons doesn't change that fact.

Like butterfly knives, many places in the us too. Ny for instance, cops are taught to flick knives open to be able to charge for knives no reasonable person would think fit the gravity description I read once.

Auto-translate is saying 'snap knife', but I'd imagine it's to do with it being deployable / spring loaded in some way.

[–] Spesknight@lemmy.world 19 points 1 day ago (1 children)

Background: there was a student stabbed to death in Liguria (whole other place) and so media is going crazy about anything knife related.

[–] 100_kg_90_de_belin@feddit.it 13 points 1 day ago

The students were of Egyptian and Moroccan descent, so right-wing politicians are having a field day with the whole "culture war" shit

[–] Wispy2891@lemmy.world 39 points 1 day ago (1 children)

Poor guy even got his ams with four rolls of pla confiscated ☠️

I can't imagine getting a search warrant for toys in a teenager room.

[–] ExcessShiv@lemmy.dbzer0.com 4 points 1 day ago

3D printers are not really toys though, regardless of how ridiculous this arrest is. It's a tool, like a hammer or drill...nothing more, nothing less.

[–] sj_zero@lotide.fbxl.net 12 points 1 day ago

Hopefully someday these places make murder illegal so people can't kill others without violating the law.

Next we'll all see more legislation to make 3D printer software monitor everything you make and auto-report anything deemed dangerous to the elite

[–] artyom@piefed.social 14 points 1 day ago* (last edited 1 day ago) (1 children)

he printed some PLA shivs that would probably shatter if they hit a piece of parmesan cheese.

How big of a piece of parmesan are we talking? Ever tried to cut into a wheel of cold parmesan? It's pretty tough. Meatbags are a lot less tough.

That being said, we learned how to make knives by smashing a couple of rocks together like a thousand years ago, this ain't stopping nobody.

[–] Agent641@lemmy.world 5 points 1 day ago

I can confirm it's much harder to stab a wheel of parmesan cheese than a person, but at least the cheese doesn't scream

[–] empireOfLove2@lemmy.dbzer0.com 23 points 1 day ago (1 children)

I'm sure they'll be introducing legislation that makes owning your own means of production onerous if not illegal within a week or two. Can't be having citizens realize they can make their own replacement parts or consumer items!

[–] Stampela@startrek.website 4 points 1 day ago (1 children)

There’s a little nuance here, the kid was dumb enough to bring one of those to school, so some worry is warranted… some. Now as you can imagine this is going to have consequences, but as we do have functional gun control laws, it’ll be something inane. Probably won’t impact 3D printing at all is the upside.

[–] empireOfLove2@lemmy.dbzer0.com 6 points 1 day ago (1 children)

Italy is fairly rightwing and has been drifting more right over time. Don't underestimate their ability to not let a crisis go to waste!

[–] Stampela@startrek.website 2 points 1 day ago

Yeah, but we seem to like hampering the right to manifest, so I’m sure it’ll get thrown in the mix.

[–] escapeVelocity@lemmy.ca 8 points 1 day ago

This guy will go to jail and start making knives for other inmates lol

[–] DaddleDew@lemmy.world 19 points 1 day ago (1 children)

That's performative. Sucks to be the student who will have his life ruined to be made "an example" out of.

The just d took a shortcut to filing a toothbrush. Those don't do shit a kitchen knife wouldn't do.

[–] Bazell@lemmy.zip 18 points 1 day ago* (last edited 1 day ago) (1 children)

People who 3D print anime weapons replicas:

[–] Kolanaki@pawb.social 7 points 1 day ago (1 children)

The swing speed on Guts' greatsword is so slow, the cops have plenty of time to unload 2 maybe even 3 magazines into them, so they're not as dangerous as the faster DPS weapons like daggers and shivs.

[–] SpikesOtherDog@ani.social 3 points 1 day ago

Yeah, but in this case it's less a sword and more a lump of plastic.

[–] BuboScandiacus@mander.xyz 4 points 1 day ago

Those knives sure are dangerous

Hope they will soon ban these too and put their manufacturer in jail:

[–] dual_sport_dork@lemmy.world 2 points 1 day ago

Well, I guess if I ever move to Italy I'll be screwed...

[–] fonix232@fedia.io 10 points 1 day ago

To be perfectly fair, a proper wheel of Parmigianino Reggiano IS quite hard...

[–] foodandart@lemmy.zip 8 points 1 day ago (1 children)

Wow. Going after letter openers now, are they?

[–] Jocarnail@lemmy.world 3 points 1 day ago

If you were to bring a letter opener to school and sell it to your friends you would still get a nice meeting with the police. The existence of the journal article is more related to the fact that a kid was stabbed to death in school last week, than to the fact that a dumb kid did something stupid and marginally related to his 3d printer.

[–] modus@lemmy.world 1 points 1 day ago (1 children)

Another murderbot off the streets. Italy is safe.

For now.

[–] spitfire@lemmy.world 1 points 1 day ago (1 children)

They need to ban printer sales

[–] lightnsfw@reddthat.com 3 points 1 day ago (1 children)

This is fucking dumb. I made a better knife than that on the bench grinder in my high school shop class. The teacher watched me do it (and immediately took it away).

[–] spitfire@lemmy.world 1 points 20 hours ago

Of course. One can make a better knife, or just take one out of a kitchen drawer.
