This legendary knife comes from the 2015 Christmas Event, where it was unboxed from the Christmas Knife Box. The event is long over, so the only way to get Tree now is through trading. The look is a wooden tree-shaped blade, which is why collectors of old event knives still pick it up. Value history shows no recorded moves, so expect a quiet, slow trade rather than quick profit.
