How Many Case Hardened Patterns Are There in CS2?

There are exactly 1,000 Case Hardened patterns in CS2, determined by pattern seeds numbered 0 through 999. Every Case Hardened skin in the game uses one of these seeds, and the seed determines the exact distribution of blue, gold, and purple across the weapon surface.

How the Seed System Works

When a Case Hardened skin is created (through case opening, trade-up, or any other method), the game assigns it a random pattern seed between 0 and 999. This seed feeds into a texture generation algorithm that produces the color distribution. The system is deterministic -- seed #661 always produces the same pattern on the same weapon model. However, the same seed looks completely different on different weapons because the texture wraps around each weapon model differently.

Fact	Detail
Total Pattern Seeds	1,000 (0 through 999)
Unique Per Weapon?	Yes -- same seed looks different on different weapons
Random Distribution?	Each seed has equal probability (~0.1% each)
Can Be Changed?	No -- pattern is permanent once created
Visible In-Game?	Yes -- inspect the item to see pattern index

Are All 1,000 Patterns Truly Unique?

Technically yes, but visually some patterns are nearly indistinguishable. Two seeds might produce patterns where the blue/gold distribution is so similar that only close inspection reveals the difference. At the extremes (very high blue or very low blue), patterns tend to look more distinct because the color distribution is more pronounced. In the middle range where blue and gold are roughly equal, many patterns blend together visually. This is why the community focuses on tiering patterns by blue percentage rather than trying to individually price all 1,000.

Blue Coverage Distribution

The distribution of blue coverage across all 1,000 AK-47 Case Hardened patterns is not uniform. Most patterns fall in the middle range with mixed blue and gold.

Blue Coverage Range	Number of Patterns (Approx.)	Percentage of Total
85-100% (Blue Gem)	~10-15	~1-1.5%
65-85% (Elite Blue)	~30-50	~3-5%
45-65% (Strong Blue)	~100-150	~10-15%
25-45% (Partial Blue)	~200-250	~20-25%
0-25% (Gold/Minimal)	~550-600	~55-60%

This distribution explains the pricing curve perfectly. Blue Gems are expensive because they represent only 1-1.5% of all possible patterns. Most Case Hardened skins will be predominantly gold or mixed, which is why the base price for a "normal" Case Hardened skin is relatively modest.

Pro Tip: The pattern seed is displayed when you inspect a skin in CS2. Look for "Pattern Template" or "Paint Seed" in the item details. This number is your key to identifying exactly which of the 1,000 patterns you have.
