What's the most efficient way to attach model to player's hand/anything else

what do you mean by this? also following the steps that you posted above (post 43) nothing worked for me, and I want this to appear for every player, so would getting the character by using workspace.F0xBirdman only work if im in the server? also, how would i get the players torso through a server script? EDIT: The LeftHipAttachment creating worked, but it was through a local script
