Knife skins are the most coveted and expensive items in CS2, with the rarest examples reaching prices that rival luxury cars and real estate. While knives dominate the high-end market, Revolution Case gloves and other Clutch Case gloves also command serious money in the CS2 economy.
Knife skins don't affect gameplay, but they're the ultimate status symbol whether you're grinding CS2 ranks or just collecting. The rarest knives cost more than most people's annual salaries.
The Quick Answer
The most expensive CS2 knife is the Karambit Case Hardened "Blue Gem" pattern #387 in Factory New condition, valued at an estimated $1.5 to $2 million. It is the only Factory New copy in existence, and its owner rejected a seven-figure offer in 2021 because it was "too low". Since no verified public sale has ever taken place, that figure is based on rejected offers and collector estimates rather than a confirmed transaction.

Prices reflect mid-2026 marketplace data and documented sales. High-end knives mostly trade privately, so real transaction prices can sit well above public listings.
The Crown Jewel: Factory New Blue Gem Karambit
What Makes This Knife Worth $1.5 Million?
The most expensive CS2 knife combines several ultra-rare factors:
- Knife Type: Karambit - The most desired knife model with its distinctive curved blade
- Skin: Case Hardened - Allows for unique pattern variations
- Pattern: #387 "Blue Gem" - Near-100% blue coverage on the play side
- Condition: Factory New with 0.0480 wear rating
- Uniqueness: Only one known to exist with this exact combination
The Case Hardened pattern system randomly generates color distributions, with blue being the rarest. Most Case Hardened knives feature primarily gold and purple tones, making a near-100% blue pattern extraordinarily rare - essentially a perfect storm of RNG that may never be replicated. You can see how #387 compares to other top patterns in CSGOSKINS.GG's Karambit Blue Gem pattern guide.
The $1.5 Million Offer That Got a Flat "No"
In September 2021, an anonymous buyer made an offer for the knife worth roughly $1.5 million - reported as around 1.2 million euros paid in Bitcoin, just over 22 BTC at the time. The offer was relayed through a middleman (ohnepixel2) because both parties wanted to stay private.
The owner's reply became CS2 trading legend: "Not interested, 1.2 is low." Rumors of a later offer closer to $2 million being rejected have circulated since, though that one has never been confirmed.
That refusal is why this Karambit is considered the most expensive knife skin not just in Counter-Strike, but in any video game. For context, the same pattern #387 in Well-Worn condition - a far worse float - sold for around $120,000 in June 2023.
How Rare Is the Blue Gem Karambit?
It's easy to ask what the chances are of getting this knife from a case.
With over 930 million cases unboxed, the odds of pulling the rarest knife work out to roughly 0.00000010695%. Needless to say, it is probably never dropping again.
Remember, it also needs the near-100% blue pattern and a wear rating of 0.0480 or better. That combination has happened exactly once.
What Case Did the Blue Gem Karambit Come From?
The 2013 CS
Weapon Case was the first case the skin came from. Other cases where expensive Case Hardened knives can drop include:-
Weapon Case
-
Weapon Case 2
-
Weapon Case 3
-
eSports 2013 Case
-
eSports 2013 Winter Case
-
eSports 2014 Summer Case
-
Revolver Case
-
Operation Bravo Case
-
Operation Phoenix Weapon Case
-
Operation Vanguard Weapon Case
-
Winter Offensive Weapon Case
Released on the 14th of August, 2013, the Karambit Case Hardened quickly became one of the most popular pulls for unboxers. The one-of-a-kind Blue Gem dropped with a wear rating of 0.0480 and pattern template 387.
Who Owns the Most Expensive CS2 Knife?
As of 2026, the knife belongs to a Chinese collector known as "Newb Rage", who also goes by "青い王" - a name that translates to "Blue King". He remains one of the most mysterious figures in CS2 trading.
The collector is extremely private and only talks to a select few people, who are themselves secretive about those conversations - especially regarding this knife.
Why Are Blue Gems So Expensive?
It comes down to supply and demand. With such a limited supply of perfect or near-perfect patterns, no new supply can enter the market - even Valve's 2025 knife trade-up system can't produce a specific pattern and float on demand.
Prices at this level are set by whatever the wealthiest collectors are willing to bid against each other. Some figures in the Counter-Strike scene believe the #387 Karambit would clear $2 million if it ever sold publicly, though that remains speculation until a documented sale happens.
The CS2 Knife Market in 2026
The market changed dramatically on 23 October 2025, when Valve let players trade up five Covert skins into a knife or gloves from the same collection. Roughly $2 billion in skin market value evaporated within 48 hours as generic knife prices collapsed - the Butterfly Knife Gamma Doppler Emerald, for example, fell from about $20,000 to $11,000 almost overnight. CSMarketCap's crash analysis breaks down the damage in detail.
The recovery was fast. The total CS2 skin market cap climbed back past $5.5 billion within weeks and sits around $7.5 billion as of June 2026. One-of-one collectibles like the #387 Karambit held value through the crash because no trade-up contract can replicate a specific pattern and float.
Typical knives still range from $100 to $500, while rare patterns and conditions push into five and six figures. With case keys around $2.50, the unboxing economy is as busy as ever - and if you want to inspect skins properly in-game, our CS2 console commands guide covers weapon inspection and display settings.
Understanding Knife Pricing in CS2
Factors That Determine Knife Value
- Rarity - Drop rate, case availability, and trade-up eligibility
- Pattern - Unique patterns like Blue Gems or specific fades
- Wear Rating - Factory New commands the highest prices
- Knife Type - Karambits and Butterfly knives are most sought after
- StatTrak™ - Adds a significant premium on rare combinations
- Market Demand - Popular designs command premium prices
Other Expensive CS2 Knives Worth Noting
Beyond the legendary Blue Gem, several other knives command impressive prices. Just as Recoil Case gloves and Snakebite Case gloves offer premium cosmetic options for hands, these knives represent the pinnacle of weapon skins:
Butterfly Knife Marble Fade ($1,500-$2,000)
Released in 2017 through the Spectrum cases, the Butterfly Knife Marble Fade combines two highly desired elements: the flashy butterfly knife animation and the colorful marble fade pattern. Factory New versions with optimal "Fire and Ice" color patterns sit at the top of that range in 2026.
Stiletto Knife Crimson Web ($1,300-$2,700)
The sleek Stiletto paired with the iconic Crimson Web pattern creates a sought-after combination. Factory New versions are rare because Crimson Web tends to spawn in lower conditions, and FN listings ranged from roughly $1,300 to $2,700 in mid-2026.
M9 Bayonet Crimson Web ($6,000-$15,000+)
One of the original high-tier knives from 2013, the M9 Bayonet Crimson Web in Factory New condition is exceptionally rare. FN listings start around $6,000, while StatTrak™ Factory New versions have sold for over $15,000.
M9 Bayonet Gamma Doppler ($9,000-$11,000 for Emerald)
Standard Gamma Doppler phases are far more affordable, but the Emerald phase is a different story at $9,000 to $11,000 in 2026. The vibrant green coloration and sub-0.1% drop rate make it a staple of high-end collections.
