How do I keep a player's items when they die?

I have the tool save set up and everything but the one remaining issue is that I can't get the player to keep their purchased weapons (those not in the starter pack) when they die. When the player respawns they will have an extra starting weapon for each time they died. For example, if I have an MP7 in my hand when I die, that MP7 will be gone on respawn and there will be another starter pistol. If I die again, the purchased weapon disappears and ANOTHER pistol gets added, which means on respawn the player will have a bunch of pistols but no weapons they actually bought. I'll show the whole script but there's one part I'm almost certain is the reason, unless I'm missing something else.

local ss = game:GetService("ServerStorage")
local ds = game:GetService("DataStoreService")
local store = ds:GetDataStore("ownedTools")
local Tools = ss:WaitForChild("Tools")


local dir = {}

local function edit(player, list)
    dir[player.UserId] = list
end

local function setup(player, list)
    for i = 1, #list do
        local tool = Tools:FindFirstChild(list[i])
        if tool then
            local clone = tool:Clone()
            clone.Parent = player.Backpack
        else
            print(list[i].." not found")
        end
    end
end

game.Players.PlayerAdded:Connect(function(player)

    local ready = false

    player.CharacterAdded:Connect(function(char)

        local bp = player.Backpack
        local data = nil

        if ready == false then
            ready = true

            data = store:GetAsync(player.UserId)

            if data then
                setup(player, data)
                edit(player, data)
            end
        end

        char.Humanoid.Died:Connect(function()
            char.Humanoid:UnequipTools()

            local old = player.StarterGear:GetChildren()
            for i = 1, #old do
                old[i]:Destroy()
            end

            local new = player.Backpack:GetChildren()
            for i = 1, #new do
                new[i].Parent = player.StarterGear
            end
        end)

        local count = 0
        local function adjust()

            if char.Humanoid.Health > 0 then

                local list = {}
                local equipped = char:FindFirstChildOfClass("Tool")
                if equipped then 
                    table.insert(list, equipped.Name)
                end

                local tools = bp:GetChildren()
                for i = 1, #tools do
                    table.insert(list, tools[i].Name)
                end

                if count ~= #list then
                    edit(player, list)
                    count = #list
                end
            end
        end

        bp.ChildAdded:Connect(adjust)
        bp.ChildRemoved:Connect(adjust)

        char.ChildAdded:Connect(function(child)
            if child.ClassName == "Tool" then
                adjust()
            end
        end)

        char.ChildRemoved:Connect(function(child)
            if child.ClassName == "Tool" then
                adjust()
            end
        end)

    end)
end)

game.Players.PlayerRemoving:Connect(function(player)
    store:SetAsync(player.UserId, dir[player.UserId])
    dir[player.Name] = nil
end)

game:BindToClose(function()
    wait(5)
end)

This is the entire script. Again, the save and load work, it's this next part below that I believe is giving me trouble.

char.Humanoid.Died:Connect(function()
            char.Humanoid:UnequipTools()

            local old = player.StarterGear:GetChildren()
            for i = 1, #old do
                old[i]:Destroy()
            end

            local new = player.Backpack:GetChildren()
            for i = 1, #new do
                new[i].Parent = player.StarterGear
            end
        end)

This is supposed to loop through and give the player back what they had when they died but it is destroying whatever is being HELD and adding another starterGear weapon. If the player is NOT holding a purchased weapon when they die, the purchased weapon stays in the backpack on respawn. This is giving me more trouble than anything else thus far. This is my first game so any help is appreciated!
