How Rare Is a Knife in CS2? Drop Rates Explained
A knife in CS2 is classified as "Exceedingly Rare" -- and the name is not an exaggeration. At roughly 0.26% per case opening, knives are by far the rarest item category you can unbox. Here is a complete breakdown of what that rarity means in practical terms.
Rarity Tiers in Context
| Rarity | Color | Drop Rate | Times Rarer Than Blue |
|---|
| Mil-Spec (Blue) | Blue | ~3.20% | 1x (baseline) |
| Restricted (Purple) | Purple | ~0.64% | 5x rarer |
| Classified (Pink) | Pink | ~0.13% | 25x rarer |
| Covert (Red) | Red | ~0.026% | 123x rarer |
| Knife/Glove (Gold) | Gold | ~0.26% | 12x rarer than blue |
Wait -- knives are actually more common than Covert reds? Yes. This surprises many players. The knife/glove tier sits at about 0.26%, while individual Covert skins are around 0.026% each. However, the knife tier contains many possible outputs (different knife models and finishes), so while you have a 0.26% chance of getting any knife, the chance of getting a specific knife is much lower.
Visualizing the Odds
If you imagine 10,000 case openings happening simultaneously across the CS2 player base, here is roughly what the outcomes would look like:
- ~7,992 cases would produce Consumer Grade (white) items
- ~1,598 cases would produce Industrial Grade (light blue) items
- ~320 cases would produce Mil-Spec (blue) items
- ~64 cases would produce Restricted (purple) items
- ~13 cases would produce Classified (pink) items
- ~3 cases would produce Covert (red) items
- ~26 cases would produce a knife or gloves

Psychology plays a role in the perceived rarity. When you open cases, the near-miss effect (seeing a knife flash past on the spinner) creates an illusion that you were "close." In reality, the spinner animation is purely cosmetic -- the result is determined server-side the instant you confirm the opening. Additionally, content creators who post unboxing videos have a survivorship bias -- you see the rare knife openings because those are the clips that go viral, creating a skewed perception of how often knives actually appear.
Note: The ~0.26% figure is a community-derived estimate from millions of tracked openings. Valve has never confirmed the exact rate. Actual rates may vary slightly, and there is ongoing debate about whether rates differ between cases or remain perfectly uniform.
