The M9 Bayonet Case Hardened is one of the most recognizable and prestigious knives in CS2. Its large blade makes the Case Hardened pattern especially visible, and some patterns with dominant blue coloration are among the most desirable skins in the entire game.
As with other Case Hardened skins, the knife’s appearance depends on the pattern seed, a number from 1 to 1000 that determines how the texture is distributed across the blade.
Most seeds generate a mix of gold, purple, and blue areas. However, only a small portion of patterns feature a very high coverage of blue color – these variants are known as Blue Gems.
M9 Bayonet Blue Gem
Every M9 Bayonet Case Hardened uses the same texture, but its placement changes depending on the seed.
Key information:
- the pattern seed ranges from 1 to 1000,
- only a small number of seeds generate patterns with a dominant blue color,
- for the M9 Bayonet, the most important area is the blade playside,
- the larger the area of pure blue color, the higher the collectible value.
Due to its large blade, the M9 Bayonet is one of the knives where the Blue Gem effect appears particularly striking.
M9 Bayonet Blue Gem Seed Ranking
The trading community divides Case Hardened patterns into three quality tiers.
Tier 1 (T1)

Tier 2 (T2)
Patterns with a large amount of blue but with a noticeable mix of gold or purple.
Tier 3 (T3)
Seeds with smaller blue areas that may still look attractive but are not considered top-tier Blue Gems.
