Make this script only work on LocalPlayer?

How would I make this script only work on LocalPlayer but still be inside of its part?

local tool = game.ServerStorage.Sword

game.Players.PlayerAdded:connect(function(plr)
    plr.CharacterAdded:connect(function(chr)
local function onTouch(part)
    if plr.Backpack:FindFirstChild('Sword') ~= nil then
plr.Backpack:FindFirstChild('Sword'):Remove()
    end
    end

script.Parent.Touched:connect(onTouch) 
    end)
    end)
