Ghost

Ghost carries a notice on its wiki page because the name is shared with a Legendary knife, Ghost (Knife); this entry is the Vintage one, sold in the Murder Mystery 1 shop for 1,200 Points or 20 Cash and now available only through trading. A partner gun with the same name exists too.

The smallest knife

The wiki calls it the smallest and shortest knife in the game. Its spearhead-like blade is a teal-white tone and there is no guard; dark grey tape wraps the lower part to serve as a handle, and since the tang is still partly visible, the handle is too short to cover all of it.

Why players liked it

Before Murder Mystery was renamed Murder Mystery 2, Ghost let players throw knives easier and faster, similar to the Sleight power. The wiki also notes that players like it because it can be hidden behind the teddy bear emote: equip the teddy bear first, then equip the knife with the Equip button rather than the knife button in the inventory. It adds that some bugs involving Ghost, now patched, once gave it a lot of hype.

Its model and texture come from the Roblox gear Ghostfire Throwing Daggers, and it is one of the ten weapons in the Vintage Set.
