Skins by rarity

13 weapon finishes from Mil-Spec up to Covert, plus a knife behind the case.

  • Covert: M4A4 Asiimov and Sawed-Off The Kraken.
  • Classified: the AWP Redline is an all-time classic, alongside the M4A1-S Guardian and P250 Mehndi.
  • Restricted and Mil-Spec: FAMAS Pulse, MP9 Rose Iron, M249 Magma and more, from a dollar up.

The rare item: M4A4 Asiimov

The M4A4 Asiimov is the original Asiimov, a sci-fi design in white, orange and black that later defined the whole Asiimov line across other weapons. Its 0.18 float floor means there is no Factory New or Minimal Wear, so copies start at Field-Tested around €172 and climb in StatTrak, and the Sawed-Off The Kraken is the second Covert.

"This is the Asiimov that started it all. The M4A4 defined a design language the whole game copied."

Where the skins come from

Winter Offensive Collection skins drop from the Winter Offensive Weapon Case, which holds a knife as its rare special. Compare live prices on our markets page.

Trade-up contracts

You can trade up ten same-rarity skins from this collection toward the tier above, and since 2025 you can craft a knife from five Covert items. The expected value is negative, so craft for the item, not the profit.

As a collector item

Winter Offensive is a 2013 case that has long left the drop pool, so supply is fixed and the collection carries early-era interest. The M4A4 Asiimov and the classic AWP Redline anchor demand. A strong long-term hold.
