Non-Craftable Professional Killstreak Fists Kit

Used to add killstreak properties to an item. Killstreak effects must be removed from an item via Restore button before a new kit can be applied.

This Professional Killstreak Fists Kit appears as an industrial assembly consisting of a metallic oil can, a vertical LED display, and various exposed electronic circuit boards. A single droplet of oil hangs from the spout, completing the rugged, utilitarian aesthetic of the components. When applied, this kit upgrades the target item to track killstreaks and adds a specialized sheen effect that cycles across the weapon surface. Upon reaching a high enough killstreak, it also enables a unique, pulsating eye-effect around the player's character.
