Knifeless sim slab
Every pull is graded like a collectible card: tier, wear, float and pattern sealed on a slab. Classified and rarer pulls get a foil.
Winter Offensive Weapon Case
The Winter Offensive Weapon Case puts AWP | Redline, M4A1-S | Guardian and P250 | Mehndi in its classified tier, which comes up on 3.2% of opens. Covert is the next step up: M4A4 | Asiimov and Sawed-Off | The Kraken split 0.6% between them.
At the top is a rare special tier made only of knives, 65 finishes in all. The case has StatTrak versions.
Restricted and mil-spec skins fill out the rest of the case. The simulator rolls every open from these odds, and no open depends on the one before it.

Questions
- What is inside the Winter Offensive Weapon Case?
- The case holds 13 weapon skins under its knife tier. Below the classified skins come the restricted Dual Berettas | Marina, FAMAS | Pulse, MP9 | Rose Iron and Nova | Rising Skull, and then the mil-spec Five-SeveN | Kami, Galil AR | Sandstorm, M249 | Magma and PP-Bizon | Cobalt Halftone.
- What knife can you get from the Winter Offensive Weapon Case?
- Any of ★ Bayonet, ★ Flip Knife, ★ Gut Knife, ★ Karambit and ★ M9 Bayonet. They share one set of finishes, so every type exists in patterns such as ★ Karambit | Crimson Web, ★ M9 Bayonet | Fade, ★ Bayonet | Case Hardened and ★ Gut Knife | Night, and in a version with no finish at all.
- When was the Winter Offensive Weapon Case released?
- The Winter Offensive Weapon Case first appeared in the game on December 18, 2013. Its 65 knife finishes cover every knife type in the case: ★ Flip Knife | Fade, ★ Bayonet | Slaughter, ★ M9 Bayonet | Blue Steel, ★ Karambit | Stained and ★ Gut Knife | Scorched are a few of them, one for each type.
- What is the drop rate for the Winter Offensive Weapon Case?
- Mil-spec skins drop on 79.9% of opens, restricted skins on 16% and a knife of any type on 0.3%. Those are rates per tier: an open settles on a tier and then on one item in it, so a single finish such as ★ Karambit | Slaughter is far less likely than its tier.
- Is the Winter Offensive Weapon Case worth opening?
- The answer changes with prices, so it lives in the expected value block on this page: the average item value an open produces at these odds, before fees, measured against the price of the case and its key. ROI and profit chance are computed next to it, with no verdict from us.
