Opening cases in CS:GO and CS2 is always a gamble, but for players chasing knives specifically, not all cases are equal. Each case contains its own knife pool, and some cases are known for holding the most desirable, expensive, or unique blades. Below is a breakdown of the best cases to open if your goal is to get a knife.
General Knife Drop Odds + Best Cases for Knives
- The chance to unbox any knife is about 0.26% (~1 in 385 cases).
- This percentage is the same across all cases, but the type of knife depends entirely on the case you open.
- Some cases contain exclusive knife models or finishes that can only be found there, which is why choosing the right case matters.
Operation Breakout Case
- Exclusive knives: Butterfly Knife (one of the most popular and expensive knife models).
- Reason to open: The Butterfly Knife is only available from a few cases, and Breakout is the original source.
- Market value: Butterfly Fade, Doppler, or Slaughter versions often reach thousands of dollars.
Operation Hydra Case
- Exclusive knives: Hydra case contains the rare set of special gloves instead of knives, but it also includes the classic knife pool.
- Reason to open: Not the best pure knife case, but due to limited supply and expensive contents, it remains highly desirable.
Gamma Case & Gamma 2 Case
- Exclusive knives: Gamma Doppler finishes (Emerald, Ruby, Sapphire, Black Pearl, Phase 1–4).
- Reason to open: Gamma Dopplers are some of the most famous and valuable knife skins. Only these cases can drop them.
- Market value: Gamma Doppler Emerald is one of the most expensive knives in the game.
Chroma Case Series (Chroma 1, 2, 3)
- Exclusive knives: Introduced the Chroma finishes (Doppler, Marble Fade, Tiger Tooth, etc.) across multiple knife models.
- Reason to open: Wide variety of high-value finishes. Chroma 2 and 3 expanded the availability to more knife types.
Huntsman Weapon Case
- Exclusive knives: Huntsman Knife (unique blade model).
- Reason to open: The Huntsman Knife is only available through this case and a few others. Certain finishes (Fade, Crimson Web) are highly sought after.
Shadow Case
- Exclusive knives: Shadow Daggers (the only case to first introduce them).
- Reason to open: Although controversial in style, rare Shadow Dagger finishes like Fade and Marble Fade are still valuable.
Operation Vanguard Case
- Exclusive knives: The case features the standard knife pool but is valued because it was one of the early cases to expand availability of popular knife finishes.
- Reason to open: Older case with collectible status.
Price Efficiency and Availability
- Older operation cases like Breakout, Hydra, and Vanguard are expensive on the market because they are discontinued. Opening them costs much more but gives access to exclusive knives.
- Gamma and Chroma cases are more available and cheaper, making them better for players who want a realistic chance at a rare Doppler or Fade knife.
- StatTrak versions of knives can be unboxed, but the odds are even lower — roughly 10% of the knife odds.
