CS2 Knife Trade-Up: Every Recipe Priced and What You Get Back (2026)

Short answer: five Covert skins trade up into one knife from the knife pool of the case those skins came from. We priced all 45 CS2 containers on 1 September 2026 and found 23 knife recipes that can be costed honestly. Exactly one of them, the Operation Phoenix Weapon Case at plus 2.7%, returns more than it costs, and it stops doing that the moment you pay a selling fee. The popular cheap one, five Battle-Scarred AWP Chrome Cannons from the Kilowatt Case, costs $111.20 and returns $62.06 on average. Buying the cheapest Kukri Knife outright costs $36.91 and you pick the finish.

What the five-Covert knife trade-up actually is

Answer: it is a Trade Up Contract that takes five Covert skins instead of the usual ten, and returns a knife or a pair of gloves instead of a weapon skin. Valve added it in the Counter-Strike 2 update of 22 October 2025.

The patch note reads: “Extended functionality of the Trade Up Contract to allow exchanging 5 items of Covert quality as follows: 5 StatTrak Covert items can be exchanged for one StatTrak Knife from a collection of one of the items provided. 5 regular Covert items can be exchanged for one regular Knife item or one regular Gloves item from a collection of one of the items provided.”

Two details in that sentence do most of the work. The output comes from a collection one of your inputs belongs to, so the case you buy inputs from decides which knives you can possibly land. And the output is a knife or gloves, which is not a coin flip: it depends entirely on what that case holds. Everything else works like the standard contract covered in our CS2 trade-up contracts guide, including the fact that you lose all five inputs no matter what comes out.

That one patch note is also why knife prices sit where they do. Knives and gloves fell 53% to 60% over the following year while the cheap end of the Covert tier rose, several of those skins by more than 500%, which we traced item by item in our CS2 skin market crash breakdown. Anyone pricing a trade-up today is buying inputs at post-crash prices and receiving outputs at post-crash prices. Both sides moved, and they moved in opposite directions.

Half of the ten cheapest Covert inputs cannot produce a knife

Answer: a CS2 case carries one rare-item pool, and that pool is either knives or gloves, never both. Buy five Coverts from a glove case and the contract can only hand you gloves. Of the ten cheapest Coverts sitting in cases that hold a knife or glove pool, five can only ever make gloves, including the cheapest of the lot.

The cheapest Covert on that list, the AK-47 Head Shot at $22.22, is useless for a knife craft. The cheapest Covert that leads to a knife is the AWP Chrome Cannon at $22.24, two cents dearer. That two-cent gap is the entire difference between a Kukri and a pair of Hydra Gloves.

This is where most trade-up advice falls over. Lists of “cheap Covert skins for knife crafting” published in late 2025 and early 2026 are stuffed with glove-case skins, because the writers priced the inputs and never checked the output pool. If you want a knife, all five inputs have to come from a case that holds knives. Mixing a knife case with a glove case only adds a chance of landing the wrong category. Our CS2 gloves guide covers what the glove pools hold if that is the half you end up on.

Every knife recipe in CS2, priced

Answer: 23 of the 45 CS2 containers hold a knife pool that can be averaged honestly. One returns more than it costs. The other 22 lose, by anything from 1.3% to 85%.

Every figure below was read on 1 September 2026. The input is five of the cheapest Covert skin in that case, priced at its cheapest wear. The average result is the mean of every possible knife in that case, also at its cheapest wear, so both sides of the trade use the same basis. Sorted best to worst.

The bottom two rows are the ones worth staring at, because in both cases profit is not merely unlikely, it is arithmetically impossible. The most expensive result in the Shadow Case pool sells for $128 against a $213.15 entry. The original CS:GO Weapon Case reaches the best knife pool in the game, the legacy Bayonet, Flip, Gut, Karambit and M9 Bayonet set that tops out at a $1,794 Karambit Fade, but its cheapest Covert costs $447 a copy, so $2,235 buys a ticket whose best possible prize is $1,794. Ten other cases reach that same knife pool for as little as a seventh of the entry price.

A note on method, since the numbers depend on it. These averages assume every finish in a case’s knife pool is equally likely, which is the standard assumption and matches how those pools behave when unboxed. Valve has never published the weighting for the five-Covert contract, so treat the averages as the best available estimate rather than a published figure.

The one profitable recipe stops being profitable at the checkout

Answer: the Operation Phoenix Weapon Case returns $334.97 on a $326.25 outlay, a 2.7% edge. Sell that knife on the Steam Community Market and roughly 15% goes to fees, which turns the same trade into a 12.7% loss.

Of the 23 recipes, one clears break-even before fees and none clears it after. A 2.7% edge is also inside the noise of a market that moves a few percent a week, so a recipe that looks positive today can be negative by the time your inputs clear their trade hold. If you find a guide quoting a profitable knife trade-up, check whether it subtracted the fee. Almost none do.

Cheap entry buys bad odds, and the gap is enormous

Answer: the six recipes you can enter for under $135 lose 35.4% on average. The eight recipes costing $320 to $370 to enter lose 3.9%. Paying roughly three times more at the door cuts your expected loss by about nine times.

The reason is the shape of the pools rather than any generosity from Valve. The Kukri pool tops out at a $156 Fade, so no single result is big enough to carry the eleven that lose. The legacy pool behind the eSports and Operation cases runs to $1,794, so one good pull covers a run of bad ones. Cheap pools have thin tails, and a trade-up is a bet on the tail.

Buyers already know this, which is why the input prices sit where they do. Crafters bid up Coverts in cases with expensive knife pools until the gap narrows, and the market has done that job well at the top end and badly at the bottom. Six recipes now sit within 5% of break-even, and every one of them is an older case feeding the legacy knife pool. The recipes people actually run, the cheap modern ones, are the ones the market has left mispriced against the buyer. Paying $22.24 a skin feels like the frugal choice and is the most expensive mistake on the table.

The cheapest recipe in the game, in full

Answer: $111.20 in, $62.06 back on average. Five Battle-Scarred AWP Chrome Cannons out of the Kilowatt Case is the cheapest knife contract in CS2, and it is a 44% expected loss with one winning outcome in twelve.

The Kilowatt knife pool is twelve Kukri Knife finishes and nothing else, so this recipe does at least guarantee a knife. Here is every result, priced at its cheapest listed wear.

The median result is $45.08, which is 40% of what you spent. The single most likely experience is paying $111.20 and watching a $37 Safari Mesh drop into your inventory. The Gallery Case reaches the identical pool and costs $125.60 to enter, which makes it strictly worse.

The StatTrak version is slightly less bad

Answer: five StatTrak Coverts return a StatTrak knife, and the route cannot produce gloves at all, because no glove finish has a StatTrak version. The cheapest StatTrak run costs $121.85 and returns $74.42 on average, a 38.9% loss against 44.2% for the regular version.

StatTrak inputs cost about 10% more here while the StatTrak Kukri pool sells for about 20% more, so the ratio improves a little. It is still a loss, and it is still a loss on every other case too.

Crafting against just buying the knife

Answer: buying wins on cost, on certainty and on choice. The cheapest Kukri on the market is $36.91. The cheapest way to craft one is $111.20. You are paying three times the price for a random finish.

Our cheapest CS2 knife guide lists the budget finishes across every model, and our CS2 knife types guide covers why a Kukri and a Butterfly with identical drop odds sit hundreds of dollars apart. If the goal is owning a knife rather than gambling, the market has been cheaper than the contract since the day the contract shipped.

Why twelve cases are missing from the table

Answer: because their outcome lists cannot be averaged honestly. The Chroma, Gamma, Spectrum, Prisma, Dreams & Nightmares, Operation Riptide and Fever pools are built on Doppler finishes, and price trackers list every Doppler phase as a separate item when the game treats them as one finish with an uneven phase roll behind it.

Run the same calculation on the Prisma Case and it appears to return $510.81 on a $244.85 input, which would be free money. It is not. Those 44 rows list Doppler, Doppler Phase 1 through Phase 4, Doppler Sapphire, Doppler Ruby and Doppler Black Pearl as separate entries, up to eight of them per knife model. Counting a Talon Doppler Black Pearl at $2,440 as one forty-fourth of the pool inflates the average enormously. Operation Riptide and Fever show the same false positive for the same reason.

Any guide quoting a profitable Doppler-pool trade-up has almost certainly made this mistake. Pricing those pools properly needs the real phase distribution rather than a flat average, and our Doppler phases guide covers how uneven that distribution is. The 23 recipes in the table have no phase-based finishes at all, which is why they can be averaged straight.

What wear your knife comes out as

Answer: the wear of the output tracks the average wear of your five inputs, mapped into the float range of whichever finish you land on. Cheap Battle-Scarred inputs give you the worst wear that finish allows, which is exactly the price used on both sides of every table here.

That matching matters more than it sounds. A lot of trade-up content compares Battle-Scarred input costs against Factory New output prices, which makes almost any recipe look profitable. If you buy the cheapest inputs, you have to value the outputs at their cheapest wear too, and once you do, the edge disappears.

The exception is finishes that only exist in a narrow band near the clean end of the scale. A Kukri Fade runs $156 at its cheapest wear and $162 at its dearest, six dollars apart, so your input floats barely move its value. The full mechanic sits in our CS2 float guide and the trade-up contracts guide.

The costs that never make it into the calculator

Answer: the seven-day trade hold on the output, the fees when you sell, and the fact that buying five copies of one skin moves its price. All three make the real return worse than the table.

The knife arrives with a seven-day trade hold, so a craft you run today cannot be sold until next week at whatever the market has drifted to. Fees come next. Selling on the Steam Community Market costs roughly 15% in combined fees, broken down in our Steam market fee guide. Third-party marketplaces charge less, and the trade-offs are in our marketplace comparison and our guide to selling CS2 skins.

Then there is liquidity. A $22.24 AWP Chrome Cannon is one listing, not an unlimited supply. Buying five in a row walks you up the order book and the fifth costs more than the first. On a heavily traded skin that is a rounding error. On a thin one, like the $65.25 AUG Chameleon behind the only positive recipe here, it can wipe out a 2.7% edge on its own. Our guide to buying CS2 skins covers where the spreads actually sit.

Who should actually run one

Answer: two groups. People already holding five Coverts from the same knife case who were going to sell them anyway, and people who want the gamble and have priced what it is worth to them. Nobody else.

If your five Coverts are already sitting in your inventory, the calculation changes, because the inputs are sunk and the only question is whether a random knife or the cash is worth more to you. That is a taste question rather than a maths one. If you are buying inputs specifically to run a contract, you are buying a lottery ticket with a known negative return, and the numbers to hold onto are these: the best recipe in the game returns 87 cents on the dollar after fees, the popular cheap one returns 56 cents before them, and two cases cannot pay you back at all no matter what drops.

It is worth knowing what this mechanic sits inside legally, too. The New York Attorney General sued Valve on 25 February 2026, alleging that the CS2 case system promotes illegal gambling. Valve filed a motion to dismiss in May 2026 arguing that mystery boxes are not gambling under New York law, the Attorney General has responded, and nothing has been decided. Our guide on whether CS2 skin gambling is legal covers where that leaves players.
