In Roblox, the throw action depends on the specific game. For games like MM2 or similar knife games, the common PC controls are E or right- click , while mobile usually uses a Throw button and consoles use a trigger button.

Quick Scoop

If you mean Murder Mystery 2 , equip the knife first, then use the throw control for your platform: PC uses E or right-click , mobile taps Throw , Xbox uses LT , and PlayStation uses L2.

If you mean a different Roblox game called Shard , I couldn’t verify that game’s exact control from the available information, so the safest answer is to check that game’s in-game help, controls menu, or tutorial prompt.

Controls by device

Device| Common throw control
---|---
PC| E or right-click 28
Mobile| Tap Throw 28
Xbox| LT / left trigger 28
PlayStation| L2 8

If it is Shard

Try this in order:

  1. Equip the knife.
  2. Look for a Throw prompt on-screen.
  3. Press the game’s attack or secondary-action key.
  4. Open the game’s settings or help menu for custom controls.
  5. If nothing works, the game may use a special knife system tied to a level, power-up, or class.

Safety note

I’m keeping this to game controls only, not real-world weapon use. If you meant the Roblox game mechanic, the steps above should help.
