Karambit knives in CS2 can rightfully be called legendary. Among the skins in this category, there are many versions that are highly valued due to their uniqueness. Their cost can reach tens of thousands of dollars, so although the chance of getting such a knife when opening a case is extremely small, some players continue to hope for luck. Here are the categories of knives that are most valued.

Karambit Doppler
In CS2 there are many skins whose pattern index affects the coloring, but in few places the difference is so noticeable. Typically, this setting determines how exactly the texture will be applied to the 3D model of the weapon, with versions that have more interesting pattern elements visible being valued more. For Karambit Doppler knives, the difference is much more significant.
The variants of this knife are called “phases” and differ in their predominant color. For example, Karambit Doppler Phase 1 is painted in shades of dark blue, and Doppler Phase 2 – in shades of dark red. Without knowing the details, you might think that these are two different skins – but in fact they differ only in the pattern index.

Among the skins in this category there are several more particularly valuable options that cost even more than “phases”. They are rare and are named after gemstones based on their predominant color:
Karambit Doppler Sapphire – blue;
Karambit Doppler Ruby (ruby) – red;
Karambit Doppler Black Pearl (black pearl) – black.
Karambit Gamma Doppler
Gamma Doppler is similar in color to the options described above, but falls out of other cases. If Doppler knives can be obtained from three cases of the Chroma series, then Gamma Doppler drops only from Gamma and Gamma 2. Among them, several “phases” are also distinguished, but the most highly valued option is called Gamma Doppler Emerald. For "emerald" with a low float, collectors can pay more than ten thousand dollars.
Knives from other cases
The options described above are considered the most expensive, but the variety of the Karambit skin does not end there. It is also worth paying attention to versions that drop out of old cases that were released in the early years of the game, for example, from cases from the eSports and Weapon Case series. The most expensive “prey” that can be obtained from them – knives with patterns Crimson Web, Case Hardened and Fade. In all three cases, the pattern index can greatly affect the price.

Before this, we mainly mentioned knives painted in bright colors, but more minimalist colors are also of interest to collectors. Plus, you don't have to shell out a fortune to buy them. For example, options such as Urban Maskedor Blue Steel are popular among players. Some may also like protective light coloring, such as Boreal Forest or Safari Mesh. It is not surprising that such designs are found in old cases, because at first the developers preferred more realistic colors.
In total, there are now over thirty different colors for Karambit in CS2, if you count the phases as individual skins. Not all of them are as expensive as the rarities listed above – in the same Chroma Case and Gamma Case there are other notable designs. If you decide not to rely on luck when opening cases and are ready to invest in replenishing your collection, in the Lis-Skins.com catalog you will find various varieties of this unique knife, including Fade and various “Doppler” phases.
