★ Butterfly Knife | Slaughter
The Butterfly Knife Slaughter is a Covert-rarity balisong available from the Operation Breakout Weapon Case. Its finish applies a zebra-stripe pattern — alternating bold stripes across the blade and handles — rendered in colors consistent with the Slaughter line. The butterfly knife form allows the blade to pivot freely between dual handles, facilitating rapid deployment or single-hand concealment, which explains why the design is legally restricted in many countries. Float values run from 0.01 to 0.26, keeping it toward the cleaner end of the wear spectrum. StatTrak versions are available.
