What's the best way to save what items a player has?

I'm trying to figure out the best way to save the swords a player owns. My current way is just a number for each sword but I realized this won't work for more swords. I was thinking of making a data save for every sword and making it 1 for owning and 0 for not but I thought there might be a better way.

Heres what I currently have:

game.ReplicatedStorage.Purchase.OnServerEvent:Connect(function(Player, Sword)
    if Sword == "Bronze Sword" and Player.leaderstats.Points.Value >= 25 and Player.EquipedSword.Value ~= 2 and Player.EquipedSword.Value ~= 23 then
        Player.leaderstats.Points.Value = Player.leaderstats.Points.Value - 25
        Player.PlayerGui.SwordShop.Frame.Bronze.Text = "[OWNED] Bronze Sword"
        if Player.EquipedSword.Value == 3 then
            Player.EquipedSword.Value = 23
        else 
            Player.EquipedSword.Value = 2
        end
    elseif Sword == "Iron Sword" and Player.leaderstats.Points.Value >= 50 and Player.EquipedSword.Value ~= 3 and Player.EquipedSword.Value ~= 23  then
        Player.leaderstats.Points.Value = Player.leaderstats.Points.Value - 50
        Player.PlayerGui.SwordShop.Frame.Iron.Text = "[OWNED] Iron Sword"
        if Player.EquipedSword.Value == 2 then
            Player.EquipedSword.Value = 23
        else 
            Player.EquipedSword.Value = 3
        end
    end
end)

Thanks in advance.
