Karambit | Fade
Karambit Fade is always in fashion if you score a good fade percent, especially the “Full Fade” or “99%” that collectors crave. These stand out with that bright gradient finish. Faded tip? That’s bad news—people want that full pink/gold front.

Karambit | Doppler (Sapphire)
Karambit Doppler Sapphire hits this list for a reason – nobody forgets that deep blue blade. CS2 traders always ask for these and don’t mind paying extra. Sapphires only pop up in a tiny percent of drops, so you rarely see them equipped in matches.
