M9 Bayonet | Marble Fade appeared in the CS:GO shooter on January 8, 2015, with the “Full Spectrum” update. The item is contained in every “Chroma” case as one of 30 possible knife finishes, which are special items for these cases.

Almost the entire weapon's surface (except its handle and the cutting edge) is covered with red, yellow, and blue paint, forming a gradient transition of colors into each other. The handle is a standard gray color.

The pattern index determines the percentage of colors on the knife’s surface. Players mostly prefer the patterns where the knife tip has the highest percentage of red – they are “Max Red Tip” and slightly less precious “Red Tip.” They are followed by “Max Blue Tip” and “Blue Tip.” The more usual and modestly priced pattern is “Yellow Tip.”

Float Value of the item can vary between 0.00 and 0.08 – because of that, it is obtainable only in two exterior qualities: “Factory New” and starting from 0.07 – “Minimal Wear.” Because of the narrow range of possible float values, wear has little effect on the knife's surface, resulting in abrasions along the blade’s edges.

The item is categorized as the “Covert” rarity and is available with the StatTrak kill counter. It is moderately popular among CS:GO players.
