Knife Arena Codes (September 2026)

Knife Arena is a free-for-all Roblox combat game where you fight opponents with light and heavy knife attacks to climb the leaderboard. Redeem codes here to grab free skin cases for your knife collection without grinding matches.

Working Knife Arena codes

Enter these codes exactly as shown, since they are case sensitive and often stop working once the developer rotates them out.

FREELIKE1 — Random Mystic Knife NEW
freecase — Release Case x1

How to redeem codes in Knife Arena

Launch Knife Arena on Roblox and wait for the main menu to load.

Tap the settings icon, shaped like a cogwheel, in the top-left corner of the screen.

Select the “Redeem Code” option from the menu that opens.

Type or paste a working code into the “Enter Code Here” text box, then press “Redeem”.

A successful redemption adds the reward straight to your inventory, so open the settings menu again and check your cases to confirm the code went through. If nothing shows up, retype the code carefully since a single mistyped character stops it from working.

Expired Knife Arena codes

These codes no longer redeem rewards, so skip them and stick to the working list above.

Where to find new Knife Arena codes

New codes tend to arrive alongside game updates, new skin cases, or seasonal events. The Knife Arena Discord server and the One Hit Studio Roblox community page are the places the developer posts announcements, so joining either keeps you close to the source when a fresh code drops.

Opening a Release Case unlocks new knife skins right away, giving your blade a distinct look the next time you drop into an arena.
