Remove tool from all players?

When the player is teleported back to the lobby in my round-based game, the sword in their inventory needs to be taken away.

How can I do that for all players?

I've tried looping through or removing it when they touch the lobby floor, and it DID remove it, but then they couldn't get it back because it was constantly removing it.

Code:

while true do
	wait(1)
	
	if gameMode == 1 then -- Intermission 
		-- set the intermissionTime to the intTimerlabel text ON BOTH LABELS
		interTimerLabel.Text = tostring(intermissionTime)
		interTimerLabel2.Text = tostring(intermissionTime)
		
		-- decrement intermissionTime
		intermissionTime = intermissionTime - 1
		
		-- if it hits 0, set it back to 30, switch gamemode, and teleport players
		if intermissionTime < 1 then
			-- change the current gameMode to round in progress (2)
			gameMode = 2
			
			intermissionTime = 31
			
			-- Give all the players in the game swords
			for _,player in ipairs(game.Players:getChildren()) do
				local tool = game.ReplicatedStorage.ClassicSword:Clone()
				tool.Parent = player.Backpack
			end
			
			-- teleport all the players to the arena
			target = CFrame.new(14, 1.715, 62.3) --could be near a brick or in a new area
			for i, player in ipairs(game.Players:GetChildren()) do
				--Make sure the character exists and its HumanoidRootPart exists
				if player.Character and player.Character:FindFirstChild("HumanoidRootPart") then
					--add an offset of 5 for each character
					player.Character.HumanoidRootPart.CFrame = target + Vector3.new(0, i * 5, 0)
				end
			end
		end
		
	elseif gameMode == 2 then -- Match in progress
		-- set the arenaTimer text to matchTime
		arenaTimerLabel.Text = tostring(matchTime)
		
		-- decrement matchTime by 1
		matchTime = matchTime - 1
		
		-- if matchTime gets to 0, set it back to 180, switch gamemode, and teleport players
		if matchTime < 1 then
			-- change gamemode to intermission
			gameMode = 1
			
			intermissionTime = 31
			matchTime = 181
			
			-- sword is removed when the player touches the lobby floor
			
			-- teleport all the players to the LOBBY
			target = CFrame.new(24.5, 57.305, 50.4) --could be near a brick or in a new area
			for i, player in ipairs(game.Players:GetChildren()) do
				--Make sure the character exists and its HumanoidRootPart exists
				if player.Character and player.Character:FindFirstChild("HumanoidRootPart") then
					--add an offset of 5 for each character
					player.Character.HumanoidRootPart.CFrame = target + Vector3.new(0, i * 5, 0)
				end
			end
		end
	end
end
