It might be a dumb question, just wanting to know for now and furture reference, I have looked everywhere and couldn't find a straight answer.
This is in essence how you would do it. Of course you still have to position and rotate the weld to your liking.
function weldToRightHand(player, tool) local weld = Instance.new("Weld") weld.Parent = player.Character.LeftHand weld.Part0 = tool.Handle weld.Part1 = player.Character.LeftHand end
