My herb would get trapped and Id be digging at my glorious grinder with a knife edge to save my precious. Id have to spend a good 15-20 minutes cleaning my grinder out with a blade, alcohol, anything that would get my grinder back in action. It was and is a pain in the ass. Especially when you finally get the lid loose but your pulling so hard it just bursts open and all the parties weed hits the dirt. You better run.
