▶️ The CS:GO Butterfly Knife Emerald
Valued at $7,000 to $10,000, the Butterfly Knife Emerald is highly desired for a lot more than just its striking, green finish. The rare emerald colorway, coupled with the scarcity of the knife, is what has driven up the value. With these knives being limited in supply, finding one in Factory New condition is very difficult, and it makes it even more desirable for collectors.

▶️ The CS:GO Karambit Doppler Emerald
The Karambit Doppler Emerald is priced between $8,000 and $12,000. Its value is a result of the combination of its distinct design and rarity. Karambit knives are loved by CS:GO players due to their unique curved shape, which mimics a tiger’s claw. The Doppler Emerald variant of this knife is particularly rare, which raises its value higher among CS enthusiasts.

▶️ The CS:GO Butterfly Knife Ruby
With a price tag of $8,000 to $12,000, the Butterfly Knife Ruby is highly desired. The knife is known for having smooth and fluid animations and looking really cool. When you add the Ruby version’s deep and rich coloring, it makes it look even better. Also, because the knife is part of the rare Doppler Ruby collection, its scarcity and appeal make it a high-ticket item among CS collectors.

▶️ The Karambit Ruby
The Karambit Ruby is priced between $9,000 and $13,000, and it’s well-known in the CS:GO community for its sleek design and deep red hue. The Karambit is modelled after traditional Southeast Asian blades, and it’s this iconic shape has made it one of the most sought-after knives in the game. This particular knife is a very rare collector’s item, since the Ruby variant belongs to the rare Doppler Ruby phase.

▶️ The CS:GO M9 Bayonet Doppler Sapphire
The M9 Bayonet is a large, military-style blade, which is popular among CS:GO users because of its menacing look. When you add on the Doppler Sapphire finish, which known for its awesome blue color, it looks far cooler. As well as how the knife looks, it is the fact that it comes from the Sapphire phase itself that it is such a valuable commodity, as it is priced between $8,000 - $15,000.

▶️ The Butterfly Knife Doppler Sapphire
Just like the M9 Bayonet Doppler Sapphire, the Butterfly Knife Doppler Sapphire is valued at $8,000 to $15,000. The butterfly knife’s unique animation, in combination with the rarity of the Doppler Sapphire finish, makes it a top choice for both collectors and players who enjoy showing off in-game. The most-expensive versions of this knife come when it is found in Factory New condition, as this adds significantly to its value.

▶️ The CS:GO Karambit Doppler Sapphire
Like I mentioned before, the Karambit knife is popular among CS:GO players thanks to its great looks. When you add in the Doppler Sapphire finish to this knife, the price for this knife can go as high as $15,000. Given its status as part of the limited Doppler phase, the rarity and the amazing look of the blade make it one of the most valuable knives available.

▶️ The StatTrak™ Karambit Crimson Web
Now that we are getting into the top 3, these knives are extremely rare to find. The StatTrak™ Karambit Crimson Web Priced can be priced anywhere between $50,000 and $100,000 if it is in Factory New condition. By adding StatTrak and Crimson Web to the already popular Karambit knife, it’s understandable that it comes with such a high price tag.

▶️ The CS:GO StatTrak™ M9 Bayonet Crimson Web
The StatTrak™ M9 Bayonet Crimson Web has been valued from $50,000 to $100,000 and it’s considered to be one of the most expensive knives in the game. This is a result of the combination of its rarity, as well as its functionality. The addition of the StatTrak™ feature, which tracks player kills, adds a layer of usability that die-hard CS:GO players really enjoy. As well as that the Crimson Web is a rare design, which looks epic on the large M9 Bayonet.

▶️ The Blue Gem (Karambit Case Hardened)
The Karambit Case Hardened Blue Gem (Pattern 387) is the most expensive knife in CS:GO. It may sound unbelievable, but this knife is valued over $1.5 million dollars. The value comes from the knife’s Case Hardened finish, which is one of the rarest patterns that you can get. When combined with the Karambit’s iconic design and its condition in Factory New, this one-of-a-kind knife has become a legendary status symbol in the CS:GO community. It is really one of the most expensive CS:GO Skins.
Knives in CS:GO can be worth some astronomical prices that non-CS:GO players would never understand. But, with some knives with unique combinations of patterns and special features being so incredibly scarce, it’s no wonder that these items have moved from being just weapons in a game, to extremely valuable digitized commodities worth over $1.5 million.
The Karambit Case Hardened (Blue Gem) holds the title as the most expensive CS knife, as it is valued at over $1.5 million.
A knife's value is determined by a bunch of different factors. These include the rarity of the knife, the skin pattern, and the condition (Factory New being the highest). Some knives can have special features like StatTrak, which can also raise the value. The cheapest CS:GO Knife doesn't have these features.
Although it’s impossible to say for certain, it is possible that CS:GO knife prices can rise over time, as the knives increase in both rarity and demand. As fewer Factory New knives become available and the CS player base grows, the scarcity of rare patterns or StatTrak™ features can drive the prices further.
