How to permanently remove a tool from Backpack?

I am trying to permanently remove a tool from the player's backpack.

I've tried using:

tool:Destroy()

and

tool.Parent = workspace

However, when my players dies or resets, the tool comes back to the players backpack. How do I prevent this?

Is the tool in StarterPack? If so, all tools in StarterPack are cloned back into the player's backpack when they die/reset. To prevent this, I would move the tool to ServerStorage. After moving the tool, I would make a Script with the .PlayerAdded event. Then clone the tool and parent it to the player's Backpack.

Find the players backpack, find the tool from backpack, destroy it

local player = game:GetService("Players")
local lplayer = player.LocalPlayer
local backpack = lplayer.Backpack

if die then -- Die isn't real. this is just an example. create your own variable identifying 'die'
	backpack.toolName:Destroy()
end
