Most Expensive Knife Skins in CS2 – 2025 Price Guide
The Ultimate Flex: Why CS2 Knives Can Cost a Fortune
With thousands of hours in Counter-Strike 2, one thing becomes obvious: not all knives are created equal. Some skins are just straight-up status symbols, and if you’ve ever browsed skin marketplaces, you already know there are knives priced like real estate.
These high-tier blades go for insane amounts of money, with some easily crossing $10,000 and even $1.5 million in one legendary case. But what actually makes these knives so expensive?
Let’s break down the top 10 most expensive knife skins in CS2 in 2025 and why they cost what they do.
1. Karambit | Case Hardened Blue Gem (Pattern 387)
Price: $1,500,000+
This knife isn’t just rare it’s legendary. The Karambit Blue Gem (pattern 387) features a blade almost completely covered in rich blue tones, with zero gold tint, which is extremely rare for a Case Hardened finish.
There are only 13 known Blue Gem Karambits with this level of purity, and only one with a float as low as 0.048. It’s not just a skin it’s the holy grail of CS2 collectibles. Owned by a player named Newb Rage, it holds the current record for the most expensive CS2 skin in history.
2. Butterfly Knife | Doppler Sapphire
Price: $15,500 – $26,000
If you’re after pure eye candy and slick animations, the Butterfly Sapphire is your dream skin. The deep blue gem-like blade paired with the fan-favorite Butterfly inspect animation makes this knife a collector’s favorite and a streamer’s dream pull.
Its price keeps climbing due to high demand and its iconic status in the CS2 community.
3. Skeleton Knife | Crimson Web
Price: $608 – $26,200
This knife combines sleek design with deadly aesthetics. The web pattern overlays a dark red base, and in Factory New StatTrak condition, it can sell for well over $25,000 especially with rare pattern placements.
A solid investment for players who want something edgy and rare.
4. Butterfly Knife | Gamma Doppler Emerald
Price: $17,500 – $23,000
The Gamma Doppler Emerald variant glows with an intense, toxic green hue and is rarer than the Sapphire. Only a handful exist in Factory New condition, making it highly collectible. Plus, it holds its value well compared to flashier options.
5. Karambit | Doppler Sapphire
Price: $9,100 – $17,500
A perfect blend of nostalgia and prestige, this Karambit Sapphire is a throwback to CS:GO’s most iconic blade shape. Thanks to discontinued Chroma cases and an ultra-rare drop rate (less than 0.0001%), this knife is a top-tier pick for OG fans and investors alike.
6. M9 Bayonet | Gamma Doppler Emerald
Price: $9,750 – $19,000
Want a knife that dominates both visually and physically? The M9 Bayonet’s larger blade makes it feel more imposing in-game. Add the vibrant emerald hue, and you’ve got a knife that’s not just rare it’s massive in presence and surprisingly undervalued compared to its Butterfly counterpart.
7. Karambit | Gamma Doppler Emerald
Price: $8,500 – $16,500
With a smoke-like pattern flowing across a rich green blade, this knife is a stunner. The lower the float (especially sub-0.01), the higher the premium adding thousands to the value. It’s ideal for anyone building a green-themed loadout or chasing the perfect float.
8. M9 Bayonet | Doppler Ruby
Price: $6,850 – $15,700
Aggressive, bold, and blood-red the Ruby M9 is the T-side’s favorite flex knife. With a StatTrak Factory New version hitting over $12,000, it’s become the go-to alternative for players who find Sapphires too common.
9. Karambit | Doppler Ruby
Price: $6,890 – $12,100
A legendary blade that’s as collectible as it is deadly. This Karambit Ruby is part of the discontinued Chroma series and has earned its place in skin history. With a 0.26% drop chance, it’s one of the rarest Karambit finishes to ever exist.
10. Talon Knife | Doppler Sapphire
Price: $5,000 – $9,200
Love the Sapphire look but can’t afford the Butterfly? The Talon Sapphire is your best bet. Its talon-shaped blade is unique, and at nearly half the price of a Butterfly, it’s a smart pick for collectors and players who want something fresh.
Why These Knives Are So Expensive
- Rarity: Patterns like Blue Gem or Doppler Sapphire are insanely rare drops.
- Demand: Butterfly and Karambit knives have cult followings.
- Design: Doppler and Fade patterns age well and never go out of style.
- Float and StatTrak: Low float + ST adds thousands to the value.
Big Tip: Don’t Just Check Steam Market
IMPORTANT: Steam prices are always inflated. If you’re serious about buying high-tier knives, check marketplaces like:
- Bitskins – Trusted and usually 10–20% cheaper
- Skinport – Easy UI and safe trades
Also, consider trading cases, cheap knives, or lower-tier skins for upgrades. You’d be surprised how many collectors are open to partial trades if your offer stands out.
Always compare prices across multiple platforms. A few extra minutes of research could save you hundreds or even thousands of dollars.
