I think grinders are the most useful innovation in toking during the 25 years I was away from it.
I splurged for the 3.5" Space Case Titanium. It's a nifty tool, big enough to not get lost easily around the casa. Breaking a tooth would require coarse gravel & herculanean effort.

Obviously not for seeded material. I just grind less for the bong, more for joints. It gives excellent even texture for joint rolling.
