★ StatTrak™ Butterfly Knife | Gamma Doppler Phase 4 (Factory New)

What the StatTrak™ counter does

The ★ StatTrak™ Butterfly Knife | Gamma 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 sets a deep, dark green marbling against black, giving it a moodier look than the brighter numbered phases in the same line, and still distinct from the solid-coat Emerald grail. 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 gamma doppler phase 4 — or simply the butterfly phase 4.

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

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 Operation Riptide Case and the Dreams & Nightmares Case, the two boxes carrying this knife's Gamma 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 Butterfly Knife | Gamma 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 | Gamma 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.
