It used to give you the ability to throw knifes easier and faster, similar to the Sleight power before Murder Mystery was renamed to Murder Mystery 2.

Some players love this knife because it can be easily be hidden behind the teddy bear emote. The way this is done is by equipping your teddy bear, and then equipping your knife using the "equip" button instead of the knife button in your inventory.

Ghost's model and texture originates from the Roblox gear Ghostfire Throwing Daggers.

Ghost is currently the smallest and shortest knife in the game.

There was a few bugs that were related to Ghost, which gave this knife a big hype. Most popular is Mil-Base bug, where you could be able to jump highly, if you bump into tank and jump. These bugs are patched now.

It has a partner gun under the same name.
