Prison is a brutal place filled with the worst that society has to offer. So how best to emphasize this violent nature to the viewers to draw big ratings? Show some random guy get stabbed in the kidneys with a sharpened toothbrush and left to bleed to death on the floor.

Congratulations, you just witnessed a shivving take place.

Shivs (sometimes known as shanks, as the names are interchangeable) are a common staple of most shows relating to the goings-on inside a prison, most often used for the purpose of trying to kill another inmate, either as an ordered hit for someone that's high up, or as retribution for something that the designated target did at a prior point. Bonus points if they come out during a PrisonRiot. Some inmates construct and carry shivs for the purpose of protecting themselves from violence. However, this is rarely shown, and even if it was, the punishment is the same, no matter what the reason it was made.

Because of the restrictive nature of prisons, shivs tend to be made of just about anything, ranging from the simple (such as a sharpened toothbrush) to the elaborate (a 6-foot-long pole made from tightly wrapped paper equipped with a sharpened steel tip) to the truly disturbing (two razor blades taped side by side and capable of making grievous wounds that are notoriously hard to stitch up). The construction of shivs remains a constant tug of war between the prisons attempting to stop the behavior with newer and greater restrictions, and the ingenuity of prisoners finding ways around said restrictions to continue their deadly art. See MacGyvering.

This is a case of TruthInTelevision; however, it's drastically underportrayed, as real prisons have displays showcasing hundreds of {{Improvised Weapon}}s made from the most innocuous of everyday materials.

[[folder: Anime & Manga]]
* ''Manga/{{Bleach}}'': During the Maggot's Nest storyline a prisoner takes Hiyori hostage and threatens to do her harm with a sharpened piece of stone if he isn't released. Being that it's Hiyori this plot doesn't end well.

[[folder:Film]]
* A particularly brutal shanking scene can be found in ''Film/AmericanMe''.
* ''Film/AnInnocentMan'': Shanking happens a lot in the movie, once witnessed by TomSelleck's character Jimmie and once carried out by Jimmie.
* Shivs are featured a considerable bit in ''Film/EachDawnIDie'' and at least one inmate (and possibly an abusive guard) meet their end this way. A newspaper article detailing the murder of the inmate goes as far as to report that the weapon was fashioned from a file. For some reason all the shivs look to be constructed in the same manner.
* In ''Film/ErnestGoesToJail'' a shanking doesn't occur but it's threatened if Ernest isn't allowed to win an arm wrestling match to maintain appearances that the inmate Nash is still safely locked up.
* While it's not used as a weapon the movie ''Film/IronMan1'' Yinsen's carving knife is certainly shiv-oriented in terms of its crude construction. Considering he's imprisoned at the time it definitely qualifies.
* ''Film/LawAbidingCitizen'' has a particularly brutal scene where one inmate stabs another in the neck with a T-bone from the steak they had for lunch.
* ''Film/LetsGoToPrison'': Extensive shiving and shanking is featured, but considering the subject of the movie it's often played for laughs.
* ''Film/OnTheYard'': An inmate gets stabbed in the armpit while pumping iron, meaning he also gets crushed by the weights he's lifting.
* ''Film/PitchBlack'': Riddick uses a sharpened piece of metal obtained from a crashed spaceship as his shiv of choice, both for killing and for personal grooming.
* ''Film/{{Predators}}'': Inmate Stans finds himself armed only with his shiv on the alien planet on which he's been dropped for the purpose of sport. He doesn't let that stop him from trying to kill several of the villains.
* ''Film/TheFugitive'': A prison guard winds up getting stabbed in an orchestrated escape plan while prisoners are being transported on a bus.
* ''Film/TheShawshankRedemption'': Andy Dufresne is threatened with having a shiv shoved through his ear if he doesn't submit to the rape-happy gang known as The Sisters. He manages to escape being raped by bluffing about the biting force of a dying man. ItMakesSenseInContext.
* ''Film/{{Elysium}}'': [[AxCrazy Kruger]] shanks [[SleazyPolitician Delacourt]] in the neck with a shard of a broken mirror. It's not that he's a prisoner or [[KnifeNut lacks more professional equipment]], it's just what he got at hand when [[BullyingTheDragon she gave him the tongue-lashing]].
* ''Film/TheGrandBudapestHotel'': The 'throat-slitter' made by M. Gustave's cellmates. It is used both to slice up the Mendl's pastries smuggled to them, and for its named purpose during the GreatEscape.
* ''Film/LockUp'': The gang that is trying to hassle Frank Leone can usually be seen with these. After defeating their gang leader in a fight, [[spoiler:Leone is suddenly stabbed by another prisoner and spends several weeks in the infirmary.]]

[[spoiler: Pennsatucky]] also has a wooden crucifix that has been sharpened to a point. At one point, Piper accidentally takes a screwdriver from the electrical shop that causes the prison to go into a panic due to its potential use as a weapon ([[spoiler: and later, the same screwdriver is returned to Piper specifically to be used as a weapon]]).
