Just A Hand is a melee weapon introduced with 10.1.0 update. It has no upgrades and can be used only in Sandbox mode.
It is literally useless, as it doesn't inflict any damage. When a player equips it, nothing is shown but the avatar without any items in their hands. It is meant to be a way to interact with other players, just like the others "For Sandbox" weapons.
- It is the only weapon in the game with 0 lethality.
- It is only shown in the shop if a player checks it in a Sandbox server.
