* ''BlazBlue'': One of Hazama's iconic weapons (the other being his GrapplingHookPistol Nox Nyctores, Ouroboros).

* ''VideoGame/TeamFortress2'''s Spy uses one for his main form of attack, a one-hit-KO backstab.

The butterfly knife, also known as a ''balisong'', is a traditional Filipino knife. Its design, with two rotating handles, allow it to be flipped open and closed. It will usually appear in the hands of a KnifeNut, who will perform a complex, flashy and [[KineticClicking noisy]] flip. Anything beyond a simple and quick opening is AwesomeButImpractical as the hand is vulnerable to a strike disarm throughout the manipulation.

* In ''FallingDown'', the main character [[SortingAlgorithmOfWeaponEffectiveness upgrades]] his [[BatterUp baseball bat]] in his first encounter with the gang members. The gang member flips it open in a threatening display, but can't complete the simple opening smoothly.

* In the ''WhiteCollar'' third mid-season finale "Countdown", Keller snacks on a mango while threatening Mozzie, cutting pieces off with a butterfly knife. It is locked open and not flipped, which would be difficult to do while coated in juice.

* Buckingham is playing with one when he is talking to captured D'Artagnan in ''Film/ThreeMusketeers2011''.

* ''CasinoRoyale'': Le Chiffre's bald mook uses a spearpoint butterfly knife to cut out Bond's tracker and to remove the chair's seat in preparation for the [[GroinAttack rope torture]]. It resembles a paratrooper knife in the first scene, but he flips it before and after the chair.

* In ''LethalWeapon 4'', one of [[JetLi Wah Sing Ku]]'s {{mook}}s wields a butterfly knife. Oddly, JeffImada plays the other mook.
* TheMummyTrilogy

* During the kidnapping in ''{{Marilith}}'', the title character draws a butterfly knife from the waistband of her skirt and flips it open between panels.

* In a [[http://www.youtube.com/watch?v=bIUNYuSmWe8 commercial for San Miguel beer]], StephenChow performs a manipulation with a butterfly ''bottle opener'' that impresses and attracts all the women in the bar.
** Butterfly bottle openers do exist, but that design (flat, large rectangular hole) must be wider than bottle caps. This extra width over knife blades adds weight, affects balance, and throws off flipping. Due to this inherent flaw, nearly all are cheap novelties.

* ''TeamFortress2'''s Spy uses one for his main form of attack, a one-hit-KO backstab.

Not to be confused with butterfly swords, which are single-edged short-swords that are [[DualWielding dual-wielded]] and used in Chinese Kung Fu.
