For fans of Counter-Strike 2, knives have always been the best and most valuable item in the game.

In this guide, we’ll list the most expensive CS2 knives, exploring why knives in CS2 are so expensive, and which specific models collectors and many CS2 players are after in 2026. Some people may associate the most expensive CS2 knife with classic finishes like the Blue Gem Karambit, which is renowned for its stunning deep-blue tones. Here, we’ll cover the specific factors influencing these prices, highlight the rarest knives, and discuss whether investing in CS2 knives is really worth it. Let’s get started!
Why Are Some CS2 Knives So Expensive?
If you understand what’s behind the most expensive knives in CS2, this knowledge will definitely help you evaluate the market and maybe even spot some potential investments. Here’s what influences a knife’s value:
- Rarity: Some finishes and knife models are rare, which immediately makes them more valuable.
- Pattern: Within each finish, there are specific patterns or color distributions. For example, the “Blue Gem” pattern on a Karambit or M9 Bayonet can multiply its price.
- Condition: The knife’s wear level – whether Factory New or Battle-Scarred – affects its appearance and value. Knives in pristine condition generally fetch higher prices.
- Popularity of the Knife Model: Certain knives, like the Karambit and Butterfly, are more popular due to their unique animations and designs.
For example, Blue Gems are a pattern type on certain finishes that have an almost full-blue appearance. So what is the price of the Blue Gem Karambit – the most coveted knife in CS2? Karambits with these patterns are among the most expensive in CS2. The price of a Blue Gem Karambit can soar because of the scarcity of this exact pattern and the high demand among collectors who want this particular shade. Below we have compiled the most expensive knives currently available, such as this Karambit, their prices, cases and collections.
