Checking for tool in player's backpack

[Dehspair (kanyewestfan911)]

I have this script that uses ZonePlus which creates a zone that gives player’s a sword when stepped in, and removes the tool from their hand when stepped out of. However, if the player unequips the tool, it stays in their backpack. How would I go about checking if the sword is in the player’s backpack and removing it so.

-- Get ZoneService
local player = game.Players.LocalPlayer or game.Players.PlayerAdded:Wait()
local ZonePlus = require(4664437268)
local ZoneService = require(ZonePlus.ZoneService)
local starterGui = game:GetService("StarterGui")

-- Setup zone
local group = workspace.SwordArea
local zone = ZoneService:createZone("SwordArea", group, 0)


-- Create a safe zone by listening for players entering and leaving the zone
local safeZoneCheckInterval = 0
local swordAreaName = "SFSword"
local sword = game.ServerStorage.ClassicSword
sword.Name = swordAreaName

local connectionAdded = zone.playerAdded:Connect(function(player)
	local char = player.Character
	local swordarea = char and char:FindFirstChild(swordAreaName)
	if not swordarea then
		swordarea = sword:Clone()
		swordarea.Parent = char
		--//Unequips tools
		print(player.Name.." is in safe zone")
	end
end)

local connectionRemoving = zone.playerRemoving:Connect(function(player)
	local char = player.Character
	local swordarea = char and char:FindFirstChild(swordAreaName)
	if swordarea then
		swordarea:Destroy()
		
		print(player.Name.." is not in safe zone")
	end
end)

zone:initLoop(safeZoneCheckInterval)

Local tool = character:FindFirstChild(“Sword”) or player.Backpack:FindFirstChild(“Sword”)

If tool then
tool:Destroy()
end
