★ StatTrak™ Karambit | Doppler Ruby (Factory New)

What the StatTrak™ counter does

The ★ StatTrak™ Karambit | Doppler Ruby (Factory New, FN) is the StatTrak™ copy of this skin — the same Covert ★ finish, the same look, with a kill counter built into the model. This is the Ruby phase of the Doppler line — a pure, deep translucent red chrome finish with none of the black marbling seen on other Doppler phases. Factory New is the cleanest grade this skin comes in and the one buyers pay the most for, covering the 0.00–0.07 band of the float scale. Most players just call it the karambit ruby — or the ruby karambit, depending on who is typing.

What StatTrak™ changes about the price of the Karambit | Doppler Ruby

What the counter tracks is confirmed kills, shown as a running total on the model itself. It is tied to the item, not to the owner, so the number follows the skin from inventory to inventory and only ever goes up. A StatTrak™ Swap Tool moves a count between two StatTrak™ items of the same type, which is as close to a reset as the game allows.

Where a StatTrak™ copy comes from

The StatTrak™ premium comes from scarcity: far fewer copies exist at the same finish and exterior. It is the finish and the float that set the figure, though — the kill count on a given copy barely moves it either way.

FAQ

This phase drops from the Chroma Case, Chroma 2 Case, and Chroma 3 Case — the specific run of cases that carry the Doppler line. StatTrak™ is settled at the drop: a copy either leaves the case with a counter or never has one, and it cannot be added afterwards.

Can the StatTrak counter on the Karambit | Doppler Ruby be reset?

No. The count only moves one way and stays with the item through every trade and sale. A StatTrak™ Swap Tool moves a count between two StatTrak™ items of the same type, which is as close to a reset as the game allows. It still cannot lower the number.

Does StatTrak change how the Karambit | Doppler Ruby looks?

No, apart from the counter on the model. The finish, the pattern and the float range are identical to the plain version, so at the same exterior the two look the same in hand.
