How to Get a Knife in Counter-Strike 2: Cases, Covert Trade-Ups, Market and Trading

Every player in Counter-Strike 2 already owns a knife. The plain default CT and T knives are free and always in your loadout. What most people mean by "getting a knife" is getting a knife skin, like a Karambit or Butterfly Knife, and those are among the rarest items in the game.

There are four legit ways to get one: opening cases, the knife trade-up contract, buying on the Steam Community Market, or trading with other players. This guide covers how each one works, the real odds, and the scams to avoid. Everything here reflects the game as of November 2026, including the trade-up change from October 2025, which is still live.

Quick answer

If you want one specific knife, buying it outright is almost always cheaper than chasing it through cases.

Requirements

• A copy of Counter-Strike 2 (free to play) on Steam.
• Prime Status if you want weekly Care Package drops, which can include cases.
• Steam Guard enabled. The Steam Community Market requires Steam Guard to have been active for at least 15 days, and the mobile authenticator protects you from most account theft.
• Steam Wallet funds for keys or Market purchases.

Method 1: Opening cases

Weapon cases drop from the weekly Care Package or can be bought on the Market, and each one needs a key to open. A key costs $2.49 from Valve.

The odds per case are official. Valve published them in 2017 after a Chinese regulation required it, and they carried over unchanged to CS2:

That 0.26% works out to roughly one gold item per 385 cases on average, and in glove cases the gold slot can be gloves rather than a knife. On average you spend far more on keys than the knife is worth. Treat cases as entertainment, not a plan.

Method 2: The knife trade-up contract

This is the biggest change in years. On October 22, 2025, Valve extended the Trade Up Contract so that Covert skins, the top weapon rarity, can be traded up into special items:

• 5 regular Covert skins become one regular knife or pair of gloves.
• 5 StatTrak Covert skins become one StatTrak knife. StatTrak gloves don't exist, so this recipe always returns a knife.

The result always comes from the special-item pool of a collection that one of your five inputs belongs to. The rule is still in place as of November 2026.

Step by step

1. Pick a target case. Decide which case's knives (and gloves) you'd be happy to get. Mixing collections spreads the result across several pools, while five Coverts from the same case lock it to that case's pool.
2. Check the inputs are eligible. Use Covert skins from collections that actually have a knife or glove pool, normally weapon cases. Collections without special items can't produce a knife.
3. Mind the wear. The output's float is based on the average float of your five inputs. Battle-Scarred inputs won't give you a Factory New knife.
4. Match StatTrak. All five inputs must be StatTrak or all five regular. Only StatTrak inputs give a StatTrak knife.
5. Avoid Trade Protected items. Skins you just received in a trade can't be used in a contract for seven days (see below).
6. Open the contract. In your inventory, open the Trade Up Contract, add the five Coverts and confirm. The five inputs are consumed and the special item appears in your inventory.

You still can't choose the exact knife model or finish. Since the update, Covert prices have risen while knife prices dropped, so compare the cost of five Coverts with simply buying a knife from the same case.

Method 3: The Steam Community Market

The Market is the most predictable route. Search for the knife, check the listing's wear and pattern, and buy with Steam Wallet funds. You get exactly what you paid for.

A few things to know:

• Sellers pay about 15% in fees (5% Steam, 10% CS2 game fee), which is baked into prices.
• Money from Market sales stays in your Steam Wallet. You can't withdraw it as cash.

Method 4: Trading with other players

You can trade skins you already own toward a knife through Steam trade offers. This works well if you have a pile of mid-tier skins. Since July 2025, CS2 uses Trade Protection:

• Items from a trade are protected for seven days. You can equip and play with them, but you can't sell, trade or use them in a contract during that time.
• Either side can reverse trades from the past seven days. A reversal undoes all protected trades at once, and the account that reverses gets a 30-day trading and Market restriction.

This protects you from accidental bad trades, but it also creates a new scam, covered below.

Bonus: Terminals and gloves

In 2026 Valve added Terminals, which show you an item and its fixed price before you pay. The Sealed Dead Hand Terminal, added in March 2026, has 22 new gloves in its rare pool. That makes Terminals a possible glove route, but not a knife route.

Tips and common mistakes

• Paying off-Steam. If you pay someone via PayPal or crypto for a skin, they can reverse the trade within seven days. The knife goes back to them and your money is gone. Only use payment methods that wait until protection ends.
• Logging in through links. Fake Steam login pages, stolen Web API keys and "check out my skin" links in chat are the main way inventories get emptied. Always log in on steamcommunity.com directly and never share your API key.
• Trusting "admins" or "middlemen." Treat any stranger who asks you to send items "for a check" or to "verify" your inventory as a scammer.
• Mixing StatTrak and regular inputs. A contract needs all StatTrak or all regular Coverts.
• Expecting a profit from cases. The odds are fixed and public. Spending on keys rarely pays back.
• Gambling sites. Third-party case and coinflip sites are not a legit route to a knife. Stick to the methods above.
