Tools/Swords Not working when :Clone()ed and parent set to localplayer?

So im trying to create a sword fighting arena for my roblox game, and ive got the sword giving platform down but i when i clone the sword (from and part of the game, lighting, replicatedStorage) the animations dont play and the sword is basically a paperweight. im using the default sword made by roblox, and ive tried tons of other swords and they dont work either. classic roblox sword when cloned: https://gyazo.com/45bbce474c1d0f64a98743f4279ed979 classic roblox sword when in starterpack : https://gyazo.com/20bbf2e9ac9ab553ba03dac1cc3bc66b

and solution to this, the script is in starterplayer.starterplayerscripts, the script is

wait(1)
function checkiftool(username, toolname)
	if game.Workspace[username]:FindFirstChild(toolname) ~= nil or game.Players[username].Backpack:FindFirstChild(toolname) ~= nil then
			return true
	else
		return false
	end
end
function toolplace(username, toolname)
	if game.Workspace[username]:FindFirstChild(toolname) ~= nil then
		return game.Workspace[username][toolname]
	else
	return game.Players[username].Backpack[toolname]		
	end
end
while wait(0.4) do
local Ray = Ray.new(game.Workspace[game.Players.LocalPlayer.Name].HumanoidRootPart.Position, Vector3.new(0, -10, 0))
local FloorPart = workspace:FindPartOnRay(Ray, game.Players.LocalPlayer.Character)
 local toolstate = checkiftool(game.Players.LocalPlayer.Name, 'ClassicSword')
if FloorPart == game.workspace.ArenaPart then
if toolstate == false then
	sword = game.Lighting.ClassicSword:Clone()
	sword.Parent = game.Players.LocalPlayer.Backpack
end
else
if toolstate == true then 
	toolplace(game.Players.LocalPlayer.Name, 'ClassicSword'):Destroy()
end
	end
end

its a localscript fyi
