How to make a tool delete itself from the player's inventory

I’m making this smoke grenade. I want to make it delete itself from the player’s inventory after it has been used. It is one of those grenade systems that use a cooldown before being able to use again. I’ve tried using the “Tool:Destroy()” line, but that doesn’t do anything. Help? Here’s the link to the model that I used.

if v.Name == "SmokeGernade" then 

I hope that works
