CSGO Guide: Which Cases Contain the Butterfly Knife - Complete List
In CSGO, the Butterfly Knife can be found in several cases, with the Operation Breakout Case being the first and most notable one to introduce this highly sought-after knife. Released in July 2014, this case remains the primary source for obtaining the original Butterfly Knife.
The Butterfly Knife can also be found in newer cases that feature the Chroma finishes. These include:
- Chroma Case - Chroma 2 Case - Chroma 3 Case
Additionally, you can get Butterfly Knives from the following cases:
- Gamma Case - Gamma 2 Case - Operation Phoenix Case (as a rare special item)
It's important to note that Butterfly Knives are extremely rare drops from these cases, with approximately a 0.26% chance of obtaining one. When you do get a Butterfly Knife, the skin pattern is randomly selected from the available finishes in that particular case.
The newer Operation Riptide Case also features the Butterfly Knife in its rare special items pool, offering more modern skin finishes.
Remember that all knife unboxings are considered "Covert" rarity items and are marked as "★ (Rare Special Item)" in the case contents. While these cases offer the opportunity to obtain a Butterfly Knife, the extremely low drop rate means that purchasing one directly from the Steam Market might be more practical, albeit more expensive.
For collectors and traders, the Operation Breakout Case remains particularly significant as it was the original source of Butterfly Knives in CSGO, though prices for both the cases and the knives have risen significantly over the years.
