★ StatTrak™ Ursus Knife | Doppler Ruby (Factory New)

What the StatTrak™ counter does

The ★ StatTrak™ Ursus Knife | 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. Doppler Ruby skips any secondary graphic — the whole blade is a single translucent red chrome, deep and pure with none of the black that shows up in the numbered 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 ursus ruby — or the ruby ursus, depending on who is typing.

What StatTrak™ changes about the price of the Ursus Knife | Doppler Ruby

Every confirmed kill with this weapon adds one to the number printed on the model. The count lives on the item rather than the account, which is why it survives trades and sales intact — and why it can never be wound back down. 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

Expect to pay more than for the plain version: StatTrak™ copies are much thinner on the ground at any given finish and exterior. The premium tracks the skin itself, not the counter — buyers pay for the finish and the float, and a big number adds little.

FAQ

Doppler Ruby isn't tied to a single collection — it comes from the Prisma Case and the Prisma 2 Case. 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 Ursus Knife | 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 Ursus Knife | 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.
