Rare AK-47 Case Hardened Patterns in CS2
Discover the rarest AK-47 Case Hardened patterns in CS2, including the legendary #661 Scar Pattern. Learn what makes them valuable, how tiers work, and where to find your perfect blue gem.

In the world of CS2 skins, few weapons carry the mystique and value of the AK-47 | Case Hardened. It’s a classic skin that launched with the earliest cases, and over the years, it’s become a legend—especially thanks to the community's obsession with one thing: blue gems.
What Makes It Rare?
Out of the 1000 possible Case Hardened patterns, only a handful are considered blue gems. These are the ones with mostly blue across the top side of the rifle, especially near the magazine and stock. The more vibrant and solid the blue, the rarer and more valuable the pattern becomes.
The Iconic Pattern #661

Also known as the Scar Pattern, #661 is the most valuable AK-47 Case Hardened skin in the game. Here's why it's so sought after:
Bright, saturated blue covers the top of the gun
Minimal gold and purple hues in visible areas
Stunning shine in low float (Factory New)
Flex-worthy status in the community
One Factory New StatTrak™ #661 AK was sold for nearly $1.5 million, setting a record as the most expensive skin in Counter-Strike history.
AK-47 Case Hardened Pattern Tiers

Tier 2 (Good blue in visible spots)

Pro tip: Tier 3 patterns with a blue mag still look amazing in-game—and cost far less than Tier 1.
Does Wear Matter?
Yes, it does. The Case Hardened finish uses the Patina style. That means instead of scratches, high float AKs just look duller. Lower wear = more shine = higher price. Factory New and Minimal Wear versions dominate the high-end market.
How Patterns Actually Work
When you unbox or trade-up a Case Hardened AK, the game randomly applies a segment of the texture. That’s what determines where the blue lands. Knives can land full-blue gems. But because the AK-47 is larger, it can never be fully blue. The key is blue in the right places.
Looking for a Blue Gem?
Finding a good Case Hardened pattern is hard, but that’s what makes it fun. Whether you're hunting for #661 or just something with a splash of blue, WAXPEER has tons of listings and filters to help you find your perfect AK. Who knows? You might land the next legendary skin.
