Building tools (also known as Btools) are the default tools used to build in a place. Players can get new building tools from an owner or admin of a Personal Server, while the old building tools are currently obtainable from admin commands (usually obtained by using the command !btools or ;btools) or by adding them in a game from Roblox Studio. Building tools also work on ROBLOX Mobile, except for the Move tool. When a player goes into the (now discontinued[1]) Build Mode on any of their places, they would be granted with building tools.
