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

For the ★ StatTrak™ Butterfly Knife | Doppler Phase 4, Factory New (FN) is one of two wears and takes nearly the whole scale. The float of the finish runs from 0.00 to 0.08, and Factory New covers 0.00 to 0.07. Covert rank, with the ★ mark. This is a blue butterfly knife with a kill counter, and in CS2 it drops from the Spectrum Case and the Spectrum 2 Case.

What the ★ StatTrak™ Butterfly Knife | Doppler Phase 4 looks like in Factory New

The blade is a deep blue with violet and dark swirls, like marble. The handles are black, with a bright cobalt-blue insert down the center of each, and the latch is blue too.

Factory New leaves the metal clean, so the swirls show in full. Wear is fixed at drop, while the StatTrak counter tallies kills and is never reset.

Where the ★ StatTrak™ Butterfly Knife | Doppler Phase 4 came from

No Workshop submission stands behind the ★ StatTrak™ Butterfly Knife | Doppler Phase 4: it is Valve's own work. The finish was released on March 15, 2017, and has number 421 in the Valve catalog. The sources are the Spectrum and Spectrum 2 Cases, so neither can be named as the only one.

Phase and pattern

The phase is built into the item name: "Phase 4" is chosen on the page, not when a case is opened. Even so, copies differ within the phase, since the pattern index shifts the ratio and placement of the colors on the blade. On Phase 4 a "Max Blue" variant is singled out. Doppler also has gems, Ruby, Sapphire and Black Pearl, and these are separate listings.

What to check before buying

In a ★ StatTrak™ Butterfly Knife | Doppler Phase 4 listing, these are the items to inspect:

• float: no copy inside 0.00 to 0.07 beats another by much;


• the share of blue on the front of the blade;


• the kill counter reading: it goes to the buyer as it stands.

A name tag can be put on the knife, while knives have no stickers.

What the ★ StatTrak™ Butterfly Knife | Doppler Phase 4 costs in Factory New

Getting the ★ StatTrak™ Butterfly Knife | Doppler Phase 4

From the Spectrum Case and the Spectrum 2 Case. A StatTrak version in a craft is assembled from five Covert skins, and all five must carry StatTrak. A random rare special item comes out, and neither phase nor model can be chosen.

StatTrak and Souvenir

The normal "Phase 4" is sold as a separate item, and that is where to go if the counter isn't needed. Souvenir knives do not exist. The counter cannot be zeroed: the StatTrak Swap Tool only exchanges the values of two items of the same type.

Who this wear suits

Factory New on the ★ StatTrak™ Butterfly Knife | Doppler Phase 4 is worth buying if:

• you want a blue butterfly knife from Doppler without gem prices, and you want a kill counter;


• your CS2 loadout is built on blue and black;


• float spread doesn't matter, since inside 0.00 to 0.07 the difference between listings is minimal.
