Red is one of the most recognizable colors among CS2 knife finishes, but genuinely red-dominant finishes are surprisingly rare: many finishes that sound "fiery" turn out pink, rust-colored, or mixed once you actually check them. Three finishes hold this niche best: the recognizable Crimson Web, the bright Slaughter with no Well-Worn or Battle-Scarred versions, and the predominantly red Ruby gem on Doppler. The price spread is wide: from ≈$60 for a Shadow Daggers | Crimson Web at Battle-Scarred up to ≈$10,330 for a Butterfly Knife | Doppler Ruby, which only exists in Factory New and Minimal Wear. A good balance of price and look is the Gut Knife | Slaughter, starting around $90 at Field-Tested. Below is what each one looks like, where it comes from, and what drives its price.
Shadow Daggers | Crimson Web (the recognizable pick)
The Shadow Daggers in the Crimson Web finish carry a deep red base with a black spiderweb pattern laid over it; the web's placement is driven by its pattern index, and rare copies with well-placed, prominent webbing on the visible side of the blade can carry a real collector premium. The finish arrived with the Shadow Case in September 2015, alongside the model itself, comes in all five wears, and has a StatTrak version.
Pricing here has an especially wide spread: from Battle-Scarred (≈$60) to Factory New (≈$480) — a regular copy costs a fraction of the top wear, so the "from" price doesn't reflect this model's real ceiling. The dark red look fits aggressive and horror-themed loadouts well.
Gut Knife | Slaughter (the budget pick)
The Gut Knife in the Slaughter finish carries a metallic red marble pattern over a mirrored steel base; on the best copies the marbling reads as nearly solid red, while lesser ones show more silver showing through. The finish arrived in the game in August 2013 and shows up in eleven early CS:GO cases — from the CS:GO Weapon Case through the Revolver Case, released between 2013 and 2015 — the same pool as the blue Blue Steel finish. It comes only in Factory New, Minimal Wear, and Field-Tested — no rougher wear of Slaughter has ever existed, so even the most worn copies stay capped at Field-Tested.
That narrow wear range is exactly what makes this model a convenient budget entry: pricing runs from Field-Tested (≈$90) to Factory New (≈$120), a minimal spread compared to Crimson Web. The Gut Knife remains one of the more affordable ways to carry this finish thanks to the model's comparatively low base price.
Navaja Knife | Doppler Ruby (the affordable gem)
The Navaja Knife | Doppler in its Ruby gem carries a predominantly saturated red coating on the blade, without the pronounced color mixing seen on the regular Phase 1 through 4. The finish arrived with the Prisma Case and the Prisma 2 Case (2019 and 2020) and exists only in Factory New and Minimal Wear.
The Navaja is one of the cheapest knife models to carry Doppler at all, so Ruby on it can cost several times less than the same Ruby on a Karambit or Butterfly Knife — a solid way to get a predominantly red gem without a five-figure budget. Pricing runs from Factory New (≈$290) to Minimal Wear (≈$420).
Butterfly Knife | Doppler Ruby (the premium gem)
The Butterfly Knife | Doppler in its Ruby gem carries the same predominantly red color as the Navaja, but on a model with a flip mechanism that carries its own separate premium. The finish reached the Butterfly Knife through the Spectrum Case and the Spectrum 2 Case (2017 to 2018) and exists only in Factory New and Minimal Wear.
Between the narrow float range and the model's own high base price, this is the roundup's showcase piece, not an entry point: pricing sits around $10,330 at Factory New. The Minimal Wear market for this model-and-finish pair is nearly empty, so Factory New is the price to go by. For more colorways on this model, see the best Butterfly Knife skins roundup.
Getting a Red Knife
Cases are the original source of all four finishes, though since October 2025 a matching knife can also come from a trade-up contract. Crimson Web on the Shadow Daggers drops from the Shadow Case, while Slaughter on the Gut Knife comes from the same pool of eleven early cases as the blue Blue Steel finish, from the CS:GO Weapon Case through the Revolver Case. Ruby on the Navaja comes from the Prisma Case and the Prisma 2 Case, and on the Butterfly Knife from the Spectrum Case and the Spectrum 2 Case. These cases aren't part of the main active weekly drop pool, so in practice people buy them on the market along with a key.
The second route is a trade-up contract: five regular Covert-rarity skins convert into one random knife or pair of gloves from the potential pools tied to the input items used. The contract doesn't let you pick a specific model or finish in advance: the input skins you choose only shape the set of possible outcomes. A broader look at which cases are worth buying gives more context for picking a specific container.
What Affects a Red Knife's Price
Knife model. The same finish prices very differently across models: Ruby on the budget Navaja can cost several times less than the same Ruby on a Butterfly Knife, a premium for the model's base price, not the color.
Finish tier. Ruby typically costs several times more than a regular Doppler phase: item databases show it appearing meaningfully less often, though Valve doesn't publish exact probabilities for individual variants.
Float and available wears. Doppler in any form is capped at Factory New and Minimal Wear, and Slaughter is capped at Factory New, Minimal Wear, and Field-Tested; no rougher copy of either has ever existed. Crimson Web comes in all five wears, giving it the widest price spread between a regular and a top-condition copy.
Pattern index. On Crimson Web, the web placement is determined by the pattern index — rare patterns with well-placed webbing on the visible side of the blade can cost more than average copies.
StatTrak. The kill counter usually pushes the price up, but at low liquidity for a given model-and-finish pair, a StatTrak copy's price can move unpredictably and isn't always higher than a regular copy's.

Frequently Asked Questions
Which red knife is the best starting pick without a big outlay?
The Shadow Daggers | Crimson Web is cheapest at Battle-Scarred (≈$60), but the top wear on this model costs several times more. The Gut Knife | Slaughter stays in a narrow range from ≈$90 to ≈$120 regardless of wear — a more predictable budget pick if you don't want to gamble on the top condition.
Does the Ruby gem drop as often as the regular Doppler phases?
According to item databases and community trackers, Doppler's gems (Ruby, Sapphire, and Black Pearl) show up meaningfully less often than the regular Phase 1 through 4, which is one reason they cost significantly more. Valve, though, doesn't publish an official breakdown of the odds between individual Doppler variants.
Why doesn't the Doppler Ruby Butterfly Knife have a Battle-Scarred version?
The Doppler finish is physically capped to a float range covering only Factory New through Minimal Wear. No rougher copy exists for any model carrying this finish, Ruby included.
Can you get a red knife through a trade-up contract instead of cases?
Yes, but the outcome is random: a trade-up contract of five regular Covert skins yields one random knife or pair of gloves from the potential pools tied to the input items used, not a guaranteed model or finish. If red matters more on gloves than on a knife, see the roundup of the best red CS2 gloves.
