p.s if your ''dense nuggets'' can break a tooth from the shark tooth grinders made from plastic your bud is hard and dirty ? wot kinda bud u smokin? breaks plastic? mmm i only smoke soft fluffy weed and i find the metal pins in metal grinders dont grind it very well shark tooth ones make the weed into a fine powder if u want. metal pins just breaks it up a bit .

also as i said in my last story people have had the metal pins fall out as they r stuck in not moulded from the same peice of metal as the actual grinder base.

CONCLUSION! = PLASTIC SHARK TOOTH GRINDER TEETH R STRONGER!!
