How do you get a tool to stay in your inventory on death?

Well, I have an equip button for each tool. But when you equip the tool you get it but when you die you have to equip it again. So how do you get it to stay equipped even on death? The Button Script:

local equipped = script.Parent.Parent.Parent.Handler.Equipped
local selected = script.Parent.Parent.Parent.Handler.Selected
local location = script.Parent.Parent.Parent.Handler.Location
local player = game.Players.LocalPlayer
local character = player.Character

script.Parent.MouseButton1Click:connect(function()
    if equipped.Value == nil or equipped.Value ~= selected.Value then 
        character.Humanoid:UnequipTools() 
        if location.Value == player.Backpack then
            character.Humanoid:EquipTool(selected.Value)
            equipped.Value = selected.Value
            script.Parent.Text = "Unequip"
        end
    else
        character.Humanoid:UnequipTools()
        equipped.Value = nil
        script.Parent.Text = "Equip"
    end
end)
