TOP 10 Most Expensive CS2 Knives

Why CS2 Knives Can Cost Tens of Thousands

In the CS2 economy, knives are more than cosmetics. They are digital luxury assets, status symbols, and in some cases long-term investments. The most expensive CS2 knife skins regularly sell for prices comparable to real-world luxury watches or cars.

But why do certain knives reach five- or even six-figure valuations? This guide breaks down the mechanics behind CS2 knife value, highlights record-breaking sales, and explains what collectors are really paying for.

What Makes a CS2 Knife Expensive?

Knife Type and Animation

Not all knives are created equal. Karambit, Butterfly Knife, and M9 Bayonet dominate the high-end market due to:

• Unique inspect and idle animations

• High visual presence in gameplay

• Strong demand from professional players and collectors

Skin Finish and Pattern

Some finishes are inherently rarer and more desirable:

• Case Hardened (Blue Gem patterns)

• Doppler (Sapphire, Ruby, Black Pearl)

• Gamma Doppler (Emerald)

Pattern index can multiply value dramatically, especially when combined with iconic knife types.

Float Value and Condition

For elite collectors, float values matter as much as the skin itself.

• Factory New (FN) is mandatory for top-tier pricing

• Ultra-low floats (e.g., 0.000x) command significant premiums

Rarity and Case Availability

Knives tied to discontinued or rarely opened cases appreciate faster. Limited supply + steady demand define most rare CS2 knives’ price trends.

Market Demand and Prestige

Some knives are expensive simply because everyone knows they are expensive. Prestige creates self-reinforcing value, especially in the CS2 knife market.

Most Expensive CS2 Knives

Below is the list of historically high-value knife skins. Prices are based on public sales, private trades, and verified listings.

1. Karambit | Case Hardened (Blue Gem – Pattern #387)

Price: $1,500,000+

The Karambit | Case Hardened with the #387 Blue Gem pattern is widely considered the most expensive CS2 knife ever discovered, and arguably the most valuable cosmetic item in the game’s history.

What makes this knife truly exceptional is its absolute uniqueness. Only one Karambit with this exact pattern exists. Unlike most expensive CS2 knife skins, it doesn’t have a fixed market price. Its value is defined entirely by collector demand, private negotiations, and prestige. At the time of writing, the owner reportedly rejected an offer exceeding $1.5 million, reinforcing its legendary status in the CS2 economy.

Case Hardened finishes are defined by a randomized pattern generation system, producing varying proportions of blue, gold, and purple tones. While most patterns are relatively common, a tiny fraction feature dominant blue coverage. These are known as Blue Gems, and they represent the pinnacle of Case Hardened desirability.

Pattern #387 is considered the bluest Blue Gem ever recorded for a Karambit. The play side of the blade is almost entirely deep blue, with minimal gold interference: a statistical outlier among already rare outcomes. Combined with the Karambit’s iconic curved blade and animation, this creates a perfect storm of rarity, aesthetics, and prestige.

2. Karambit | Doppler (Sapphire)

Price: $15,000+

Unlike Case Hardened Blue Gems, Sapphire Dopplers are visually consistent, which makes them easier to evaluate but no less exclusive. Their value comes from controlled scarcity and stable long-term demand, especially among collectors who prioritize clean, flawless aesthetics.

In the CS2 knife market, Karambit Sapphires are considered a benchmark luxury asset with strong liquidity at the high end.

3. Butterfly Knife | Doppler (Sapphire)

Price: $27,000+

The rich blue surface reflects light differently during movement, making Sapphire Butterfly knives especially eye-catching in gameplay.

Because Butterfly knives already have high baseline demand, Sapphire versions often command premium prices compared to equivalent Karambits, despite slightly lower overall supply.

4. M9 Bayonet | Doppler (Ruby)

Price: $9,000+

The M9 Bayonet | Doppler (Ruby) is a classic example of understated luxury. Ruby Dopplers feature a solid, saturated red blade with minimal visual noise, making them instantly recognizable without being flashy.

Ruby finishes are rarer than most Doppler phases, and Factory New examples are tightly held by collectors. While less volatile than Blue Gems, Ruby M9s are considered stable high-value knives with a predictable demand cycle.

5. Karambit | Gamma Doppler (Emerald)

Price: $20,000+

Among all Gamma Doppler finishes, Emerald stands at the very top of the price hierarchy, and when applied to a Karambit, it becomes one of the most coveted luxury skins in CS2.

Gamma Doppler skins are generated from hundreds of possible pattern variations, blending black, green, and light blue hues in different proportions. While many of these patterns are already expensive, Emeralds are unique: they feature an almost pure, saturated green blade with minimal secondary colors. This makes them instantly recognizable and extremely rare.

Rarity alone doesn’t explain the price. Emerald Karambits with ultra-low float values (starting with 0.00) are especially sought after. These knives frequently trade at $20,000 and above, with top-condition examples pushing significantly higher depending on market demand.

6. Butterfly Knife | Fade

Price: $2,7000+

The Butterfly Knife | Fade is one of the most visually striking and collectible CS2 knives, known for its multicolored gradient and wide price range. Among Fade skins, the Butterfly Knife and its close counterpart, the Karambit, consistently command the highest premiums due to their dynamic animation and rarity.

Fade skins are defined by a smooth gradient that blends pink, blue, and yellow tones, with the exact proportions varying from knife to knife. Collectors measure this variation using “Fade percentage”, which indicates how much of the blade’s surface is covered by the gradient. Lower-percentage Fades typically show around 80% of the gradient, with the remaining blade exposed as bare-metal gray. Full Fades, covering nearly 100% of the blade in the gradient, are the most desirable and expensive variants.

The interplay of Fade percentage and knife type creates significant pricing differences. Entry-level Butterfly Fades often start around $2,700, while top-condition Full Fades can exceed $15,000 in the marketplace. The combination of rarity, aesthetic perfection, and the knife’s fluid animation makes the Butterfly Fade highly sought after by collectors and traders alike.

7. Karambit | Doppler (Black Pearl)

Price: $12,000+

The Karambit | Doppler (Black Pearl) is one of the rarest Doppler outcomes and one of the hardest to value.

Black Pearls feature a dark, oil-slick appearance with subtle shifts between purple, green, and black depending on lighting. Unlike Ruby or Sapphire, Black Pearl finishes are not immediately bold, which limits casual demand but enhances collector appeal.

8. M9 Bayonet | Case Hardened (Blue Gem)

Price: $10,000+

While the Karambit emphasizes elegance and animation, the M9 Bayonet emphasizes blade surface area, which allows Blue Gem patterns to fully express themselves. High-tier patterns can display massive uninterrupted blue sections, making them visually dominant.

Collectors value M9 Blue Gems for:

• Pattern clarity

• Larger play-side visibility

• Lower price relative to Karambit equivalents

This makes them a popular choice for buyers seeking rare CS2 knives with slightly better accessibility

9. Butterfly Knife | Gamma Doppler (Emerald)

Price: $27,000+

Emerald Gamma Dopplers are defined by an almost entirely green blade, with negligible secondary coloration. On a Butterfly knife, this creates constant visual motion as the blade flips, catches light, and shifts tone during animations. These knives are extremely rare, and Factory New, low-float examples are often held off-market.

10. Karambit | Doppler (Ruby)

Price: $18,000+

Ruby finishes provide:

• Strong color identity

• Excellent visibility in-game

• Lower pattern variance compared to Case Hardened

Because of this consistency, Ruby Karambits are easier to price, easier to sell, and easier to justify as long-term holds. They remain one of the most liquid assets among expensive CS2 skins.

Are Expensive Knives Worth the Price?

For casual players, mostly no. For collectors and traders, often yes.

High-tier knives offer:

• Strong value retention

• Low correlation with regular skin market volatility

• Prestige and recognizability

Many expensive CS2 skins outperform mid-tier items over long holding periods.
