★ StatTrak™ Butterfly Knife | Doppler Sapphire (Factory New)

This is the ★ StatTrak™ Butterfly Knife | Doppler Sapphire in Factory New (FN), and the turquoise stripe on the handles is still untouched. Covert rank, with the ★ mark. The Doppler finish reached the butterfly knife with the Spectrum cases. The scale ends at 0.08, so the second and last wear is Minimal Wear (MW).

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

The blade is blue across the whole face: violet swirls at the heel, the lacquer lightening toward the tip, with light blue glints laid over it. The handles are black, a glowing turquoise stripe runs along each half, and the latch is blue too. The pivot screws and the lock are left unpainted. On this model the kill counter is placed on the blade.

The ★ StatTrak™ Butterfly Knife | Doppler Sapphire in this wear falls within 0.00 to 0.07. Paint comes off first from the cutting edge and the handle ridges, and the turquoise line dulls at its edges. In Factory New none of these areas is touched yet.

Phase and pattern

Sapphire and Black Pearl occur only on Doppler, while the green Emerald occurs only on Gamma Doppler of the same model. In CS2 all four rare variants are called gems, and the phase is in the item name.

Within Sapphire, the pattern index spreads the glints across the face and sets the depth of the swirls at the heel. Sources have no single view on a premium for a lucky index. The counter is unrelated to the artwork: the pattern and the reading are rolled separately.

Where the ★ StatTrak™ Butterfly Knife | Doppler Sapphire came from

The finish's author is Valve itself; Doppler never went through the Steam Workshop. In the Valve catalog the finish is listed under number 416. The butterfly knife itself appeared in the game earlier, with Operation Breakout in 2014. The finish was added to it only on March 15, 2017, with the Take a trip to the Canals update and the Spectrum Case. Valve described the look adjustment of Doppler in CS2 in a separate post on May 24, 2024.

What to check before buying

When choosing a ★ StatTrak™ Butterfly Knife | Doppler Sapphire, pay attention to the following:

• the counter reading: it is shown in the listing, and the number cannot be zeroed;


• the phase in the name: Doppler has seven variants, and blue copies of Phase 4 in a thumbnail can pass for Sapphire;


• the float: inside the wear the number does not affect the look, but it is checked before paying;


• the applied name: a name tag on a butterfly knife stays after resale.

The wear fits in 0.00 to 0.07, so listings look the same.

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

Here the counter adds nothing to the price: the normal version and the StatTrak™ one start level, within a percent of each other. The nearest neighbor above in the StatTrak™ line is Butterfly Knife | Gamma Doppler Emerald, only a few percent away. Downward the gap is sharp. Butterfly Knife | Doppler Phase 2 is about one and a half times cheaper than Sapphire, and Phase 4 and Phase 1 are twice cheaper or more. The cheap part of the rank trails by about an order of magnitude.

There are two wears here as well. Minimal Wear gets the top hundredth, 0.07 to 0.08, and everything cleaner goes as Factory New.

Getting the ★ StatTrak™ Butterfly Knife | Doppler Sapphire

The Spectrum Case and the Spectrum 2 Case hand over the butterfly knife as a rare ★ item, but neither the phase nor the counter is chosen at opening.

A craft is not targeted either: five Covert skins give a random knife or gloves. StatTrak™ comes only from StatTrak™ inputs, and the game does not let you mix them with normal skins.

StatTrak and Normal

The finish also has a normal version without the counter, and it starts level on price. The skin has no Souvenir variant.

Who this wear suits

Factory New on the ★ StatTrak™ Butterfly Knife | Doppler Sapphire is sensible when at least one of these fits:

• you specifically want StatTrak™ and do not want to add to the gem's price for the counter;


• the set is built on blue and turquoise, and black handles do not fight with it;


• the turquoise stripe should run evenly along the full length of the handles;


• the edge must be free of scuffs: in Minimal Wear it gives out first.
