Decorated quality is an item quality assigned to weapons with a special grade factor, exterior wear, and possible Strange counter and/or Unusual effect. They were introduced in the Gun Mettle Update. Decorated weapons are cosmetic "skins" with 6 levels of rarity referred to as Grades and a separate ranking of exterior wear referred to as "Wear." The only methods to obtain a Decorated item is through contract completion and unboxing specific weapon cases. Strange variants add a Stat Clock to the side of the weapon that tracks kills, and Civilian Grade weapons can also have a Stat Clock applied to them using a Civilian Grade Stat Clock.
