The Most Expensive Knives in CS2

Methodology, because it changes the answer

Three rules, applied before anything was ranked:

• Three marketplaces minimum. A row quoted by one market is an asking price. A row quoted by two can still be broken. We require at least three independent quotes on the exact wear being ranked, and report the median of them.
• Factory New only, and stated as such. Ranking a knife by its best wear is the fair comparison, and mixing wears in one table hides the fact that some finishes have five conditions and some have two.
• The spread is published. Every row shows the lowest and highest marketplace quote alongside the median, so you can see for yourself which entries the markets disagree about.

Of 584 knife rows in the dataset, 523 clear the three-provider bar in Factory New, and 100 of those exceed $1,000. Prices come from csdb's aggregated marketplace feed; the full per-market breakdown for any knife is on the knife database.

The two prices that prove the point

Gut Knife | Doppler – Black Pearl, Minimal Wear: $18,000. That is one marketplace, alone, with nothing to check it against. The same knife in Factory New sits near $667, quoted consistently by three markets — and the Gut Knife is one of the cheapest models in the game, with a median Factory New price across all its finishes of about $165. If you rank on maximum listing price, this item finishes near the top of your list and your whole list is discredited.

Karambit | Doppler – Ruby, Minimal Wear. Two marketplaces quote it: one at about $7,880, the other at about $27,270. Two providers were not enough. This is why the bar is three, and why we rank on Factory New where the coverage is deepest.

The same pollution runs through the whole dataset — around one knife price row in nineteen has a single source. It is the reason the numbers on this page are lower and duller than the ones you will find elsewhere, and the reason they are usable.

The ranked list

Factory New, non-StatTrak, median of three or more marketplaces, 13 July 2026.

Read the spread column as a confidence rating. Rows 1, 3, 7, 8, 10, 11 and 12 have markets within a few per cent of each other and can be taken at face value. Rows 9, 14 and 15 have a wide gap between the cheapest and dearest quote — the median is still the best single estimate, but the true clearing price could sit meaningfully either side of it.

What the list is missing, and why

The Black Pearls.Doppler – Black Pearl on the M9 Bayonet, Karambit and Butterfly all carry Factory New quotes from only two marketplaces, so none of them qualifies. Their two-provider medians would place them inside the top ten. The one Black Pearl that does clear the bar is the Talon Knife at roughly $2,810 across three markets, which would sit just outside this table.

StatTrak. Our dataset carries no StatTrak knife rows, so this is a non-StatTrak ranking. Read it as a floor.

Pattern outliers. No aggregated price captures a blue gem. A Karambit | Case Hardened has a Factory New median near $1,820, but individual seeds trade for multiples of that, and the market name is the same for all of them. Our blue gem explorer and pattern database cover the seeds that actually matter; nothing in the table above accounts for them.

Souvenir and vanilla knives. Neither exists. A knife has no Souvenir variant, and the vanilla models are not carried in this dataset.

Patterns in the ranking

• Three models take fourteen of fifteen places. Butterfly Knife, Karambit and M9 Bayonet, with a single Talon Knife. That holds across the whole roster, not just the top: taking the median Factory New price of every finish a model has, Butterfly Knife lands near $1,795, Karambit near $1,428 and M9 Bayonet near $1,106, against roughly $119 for the Navaja Knife at the bottom. The knife tier list groups the full roster if you want the layer below.
• Two finish families dominate. Ruby, Sapphire, Emerald and Black Pearl are rare phases of Doppler and Gamma Doppler, hidden behind a shared market name. Crimson Web is the only conventional finish in the top ten, and it gets there on Factory New scarcity — its float floor is 0.06, so FN copies are a sliver of the pool while worn ones trade for a few hundred dollars.
• Volume is close to zero at the top. Most of the top ten recorded no sales in the 30 days before the snapshot. These are listing prices in a market with very few trades, which is a different thing from a liquid price.
• The gap to the middle is enormous. Only 100 Factory New knife rows clear $1,000, and the cheapest qualifying rows sit under $50 — the same item class spans a factor of well over 200. Cheapest knives covers the other end.

Before you buy anything on this list

1. Check the current per-market spread on the knife database rather than trusting a number from any article, this one included. Snapshots age.
2. On Doppler and Gamma Doppler, confirm the phase — the market name hides it, and the difference between a Ruby and a Phase 4 is thousands of dollars. Our Doppler phase guide shows how to tell them apart.
3. Check the float, not just the wear label. On the finishes above, Factory New spans 0.00–0.07 and low-float examples command a premium of their own; the float guide and float checker cover it.
4. If the item is Case Hardened, check the seed before the price. See the pattern database.
5. Preview it in the loadout builder alongside your gloves — see glove and knife combos for pairings that work.
