★ Butterfly Knife | Gamma Doppler
Obtainable from the Operation Riptide Case and the Dreams & Nightmares Case, the Butterfly Knife Gamma Doppler is a Covert-tier balisong finished with black and silver metallic paint in the Gamma Doppler style. The butterfly knife, or balisong, is defined by its freely pivoting blade that fans open for rapid deployment or concealment — a design that is banned outright in many countries. The float ceiling sits at just 0.08, restricting this finish to near-mint condition only. StatTrak versions are available.
Cheapest wear we have on this page. Pattern / float overpay is extra.
