how do i weld a tool in a specific position when its unequipped?

what code do i put in to weld a tool(Handle)when its unequipped to give it a nice rpg effect

Personally, the best way to do this is to have a separate MODEL of your tool attached to a certain part of the character, and you use a for loop inside the actual tool itself so that when the tool is unequipped, the tool on the player is visible, and vice versa.
