How to make a tool to follow cursor movement

I want to make a object (tool) that will simply follow the cursor, also how could I make the camera follow the cursor?

Any help would be appreciated

Thanks,

Exsius,

I believe this would work:

Supposing the tool is welded:

local Target = (Cam.CoordinateFrame * CFrame.new(0, 0, -100)).p
RightArmWeld.C1=((CFrame.new(User.Head.CFrame.p, Target) - User.Head.CFrame.p):inverse()) * (User.Head.CFrame - User.Head.Position)
