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 0.50, 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 |
