What the StatTrak™ counter does

The ★ StatTrak™ Butterfly Knife | Doppler Phase 4 (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. Phase 4 leans into a mostly blue marbled swirl set against a black base, one of four numbered Doppler phases that Valve locks in at generation. 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 butterfly doppler phase 4 — or simply the butterfly phase 4.

What StatTrak™ changes about the price of the Butterfly Knife | Doppler Phase 4

The counter logs every confirmed kill you get with it and keeps the running total on the model. It belongs to the item and not to your account, so it travels with the skin through every trade and sale, and nothing sets it back to zero. 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

A StatTrak™ copy is far scarcer than a plain one at the same finish and exterior, so it normally costs more. How much more follows the finish and the float rather than the number on the counter — a high kill count is a curiosity, not a price driver.

FAQ

This phase comes from the Spectrum Case and the Spectrum 2 Case, the two boxes that carry the Doppler line for this knife. 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 Butterfly Knife | Doppler Phase 4 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 Butterfly Knife | Doppler Phase 4 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.
