KAT Codes (July 2026) — Knife Ability Test Codes & Music IDs
KAT (Knife Ability Test) is a fast-paced free-for-all knife fighting game on Roblox developed by Fierzaa. Players spawn into arenas, pick up knives with unique abilities, and battle to rack up the most kills before time runs out. If you landed on this page searching for KAT codes, good news: KAT now has a working code redemption system, and we list all the active codes below.
KAT added a Redeem Codes menu that unlocks once you reach level 50. Codes reward free crates, weapon passes, and other in-game freebies. We have cross-checked the active list against multiple code trackers below, and we also cover the game's Music ID (Radio Pass) feature, plus tips and strategies to help you progress faster in Knife Ability Test.
KAT also has a separate feature that involves entering codes of a sort: the Radio Pass. If you purchase the Radio Pass for 150 Robux, you can enter Roblox Music ID codes to play custom tracks during your matches. We cover that in detail below.

How to Redeem Codes in KAT
KAT (Knife Ability Test) has a built-in code redemption feature, though it is gated behind a level requirement. Follow these steps to claim your free rewards.
- Launch KAT (Knife Ability Test) on Roblox and make sure you are level 50 or higher (the redeem option is locked below that level).
- Press the crossed hammer/wrench button in the top-left corner of the screen.
- Click on Redeem Codes to open the code entry menu.
- Type or paste a working code from the table above into the text box exactly as shown.
- Press Enter to claim your reward. Repeat for each active code.
KAT also rewards you directly for playing. Every kill you score earns coins, and those coins let you open crates, buy knives, and unlock new abilities. Codes give you a head start, but consistent play is still the fastest way to build a full knife collection.
How to Use Music ID Codes in KAT
Separate from the reward codes above, KAT also has Music ID codes through the Radio Pass system. These play custom music rather than granting items. Here is how it works.
- Open Roblox and launch KAT (Knife Ability Test) (Place ID: 4592931260).
- Purchase the Radio Pass from the in-game shop if you have not already. It costs 150 Robux and is a one-time permanent unlock.
- Once you own the Radio Pass, look for the radio icon on your screen during a match.
- Click the radio icon to open the music player. You will see a text field where you can enter a Roblox Audio Asset ID.
- Paste or type any valid Roblox music ID into the field and press play. The track will play for you during the match.
Music IDs are not promotional codes. They are numerical identifiers for audio files uploaded to the Roblox library. You can find Music IDs by searching the Roblox audio catalog or by looking up specific songs on community databases. Keep in mind that Roblox updated its audio privacy policy, so only audio uploaded by the game developer or verified accounts may work reliably.
Other Ways to Get Free Knives in KAT
Beyond redeeming codes, here are the legitimate ways to earn free knives and items in Knife Ability Test.
Earn Coins Through Gameplay
Every kill you get in KAT awards you coins. The more kills you rack up per match, the more coins you earn. Focus on improving your aim and movement to maximize your coin income each round. Over time, you will accumulate enough coins to open crates and buy items from the shop.
Open Crates
KAT features multiple knife crates that you can open with coins or Robux. Each crate contains a random selection of knives with varying rarities. The free coin crates are your primary path to building a knife collection without spending real money. Save your coins for the crates that have the best odds on the items you want.
Daily Rewards and Login Bonuses
KAT periodically offers rewards for consistent play. Logging in regularly and completing matches helps you build up resources over time. While these rewards are modest compared to what you might get from codes in other games, they add up across days and weeks of play.
Trading with Other Players
KAT has a trading system that lets you exchange knives with other players. If you pull a rare knife from a crate that you do not want, you can trade it for something you prefer. Trading is one of the most effective ways to target specific items without relying on luck or spending Robux.
KAT Game Tips and Strategies
Codes give you a head start, but skill is what wins matches in KAT. These tips will help you dominate and earn coins faster.
Movement and Positioning
KAT is a fast-paced game where standing still gets you killed. Always keep moving, and use the map geometry to your advantage. Jump around corners, use elevation changes to throw off your opponents, and never run in a straight line when someone is chasing you. The players who consistently top the leaderboard are the ones with the best movement habits.
Knife Abilities Matter
Each knife in KAT has a unique ability. Some throw projectiles, others create area-of-effect damage, and a few have defensive capabilities. Learn what each knife does and adapt your playstyle accordingly. When you pick up a new knife mid-match, take a second to check its ability before charging into a fight. Using abilities at the right moment is often the difference between winning and losing a duel.
Map Awareness
KAT has a variety of maps, each with different layouts and chokepoints. Learn where players tend to cluster, where the best ambush spots are, and which areas give you a clear line of sight across the map. Experienced KAT players know every map by heart and use that knowledge to predict enemy movement and set up kills before opponents even see them coming.
Prioritize High-Value Targets
In free-for-all matches, not every target is equal. Players on kill streaks are worth more attention because eliminating them can shift the scoreboard in your favor. Watch the kill feed to track who is performing well and focus your efforts on shutting them down. This aggressive approach earns you more coins and keeps the competition off balance.
Practice Throwing Accuracy
Many KAT knives have a throwing mechanic that lets you hit players from range. Practicing your throw accuracy gives you a significant edge because most players rely on close-range melee attacks. A well-timed knife throw can eliminate an opponent before they close the distance. Spend time in matches deliberately practicing ranged throws until it becomes second nature.

KAT vs. Other Knife Games on Roblox
KAT sits in a competitive space alongside other popular knife and combat games on Roblox. Understanding how it compares can help you decide where to spend your time.
KAT vs. Murder Mystery 2: While both games involve knives, they play very differently. Murder Mystery 2 is a social deduction game where one player is the killer and everyone else tries to survive. KAT is a pure free-for-all combat game where everyone fights at once. Both games have code systems for free rewards. If you enjoy raw PvP action, KAT is the better fit. If you prefer mystery and suspense, MM2 is your game.
KAT vs. Blade Ball: Blade Ball is a newer entry in the Roblox combat space that focuses on deflecting a deadly ball rather than direct knife combat. Blade Ball does have a code system with regular code drops. KAT offers a more traditional knife-fighting experience with ability-based combat. Both games are worth trying if you enjoy competitive Roblox titles.

About KAT (Knife Ability Test) on Roblox
KAT was created by Fierzaa and has been one of the staple PvP games on Roblox for years. The game drops players into arena-style maps where the goal is simple: pick up knives, use their unique abilities, and eliminate other players to score points. Each match is a timed free-for-all, and the player with the most kills when time runs out wins.
What sets KAT apart from other combat games is its knife ability system. Every knife has a distinct special ability, ranging from explosive throws to teleportation dashes to shield deployments. This adds a layer of strategy on top of raw mechanical skill, since choosing when and how to use your knife's ability can completely change the outcome of a fight.
The game has accumulated hundreds of millions of visits on Roblox and maintains a steady concurrent player count. Its combination of accessible gameplay and a high skill ceiling makes it appealing to both casual players who want quick matches and competitive players who want to climb the leaderboard. KAT continues to receive updates from its developer, including new knives, maps, and gameplay tweaks that keep the experience fresh for returning players.
