Sweater is an uncommon knife that was originally obtainable by unboxing it from the Christmas Box during the 2017 Christmas Event. It is now only obtainable through trading as the event has since ended.
Appearance[]
It resembles the appearance of a classic ugly Christmas sweater, hence the name. The blade is primarily a holly green, but overlapping it is this red and white selburose Christmas design. Its guard is a ruby red, and the handle is a solid black, contrasting from the rest of the knife.
