FAQ

Is M9 Bayonet Vanilla CS2 a good buy, or should I invest in something more expensive?
Vanilla M9 is a timeless and minimal Covert knife. If that's your style, the Vanilla variant is definitely a great option. If you want something more colorful, go with Marble Fade or Doppler.
What are realistic M9 Bayonet CS2 price expectations if I'm upgrading from budget to gem?
Expect a jump from ~$500-$800 for classics to low 4-figures for Marble Fade/Tiger Tooth/Autotronic, and 5-figures+ for top gems (M9 Bayonet Sapphire CS2, M9 Bayonet Ruby CS2, CS2 M9 Bayonet Emerald).
Which cases are best if I want to try to get an M9 drop?
Although your chances are pretty slim, you can try Legacy cases for classic paints, Chroma series for Dopplers/Marble Fade/Tiger Tooth, and Gamma series for Gamma Dopplers/Lore/Autotronic/Black Laminate.
