Case Hardened pattern & Blue Gem
Case Hardened skins are tinted by a paint seed, one of 1000 patterns. The seed fixes the blue, gold and purple layout on the weapon, so two Case Hardened of the same wear can look completely different and trade at very different prices.
Seeds with heavy blue coverage on the most visible side are called "Blue Gems". On the AK-47 the best-known examples are seeds like 661, 670 and 955; on the Karambit, seed 387 is the reference Blue Gem. Tier lists rank seeds by blue percentage, and top patterns command large premiums over an average Case Hardened.
Because the seed is not shown in the item name, buyers check the paint seed in the inspect screen or a pattern database before paying a Blue Gem price.

Float & wear: how it works
Float is a hidden 0–1 value generated when a skin drops. It sets how worn the skin looks and which exterior name it gets. A lower float looks cleaner and usually costs more, even within the same exterior.
This skin can roll float 0.00 to 1.00, so only the highlighted exteriors exist for it.
| Exterior | Float range |
|---|---|
| Factory New | 0.00 – 0.07 |
| Minimal Wear | 0.07 – 0.15 |
| Field-Tested | 0.15 – 0.38 |
| Well-Worn | 0.38 – 0.45 |
| Battle-Scarred | 0.45 – 1.00 |
Case Hardened renders the M9 Bayonet as color case-hardened steel, the mottled blues, golds and greys produced by heat-treating the metal with wood charcoal at high temperature. No two blades share the same coloring, and copies with large concentrations of blue across the blade face are the prized ones.
