This CS2 knife was added to the game with the update A Call to Arms. Kukri Knife can drop from the Kilowatt case—but sure, the chances are very small. If you want to have it in your Counter-Strike 2 inventory, better buy a Kukri Knife in this category on DMarket.
The knife can have 12 color patterns, such as Crimson Web, Blue Steel, and Urban Masked. All CS2 Kukri Knives look amazing, and any one of them will be a notable gem in your collection.
In the real world, such knives originate from India. They are used in combat, for hunting, and some rituals.
