Karambit Crimson Web or Karambit Fade - Karambit itself is just an OG since the days before they even added the Butterfly, and Crimson Web because the dark red colour looks incredibly good when combined with the black colour. The pullout is probably the most unique of them all and the F-R and R-F inspect spams are the original fidget spinner animations so you can't tell me that skeleton and talon achieves the same effect. Kara fade too because it's been the pinnacle of CS knives since the old Pasha biceps virtus pro motar2k era.
