The grinder is every stoner’s trusted sidekick: if you meet someone who smokes weed, they most definitely have a grinder. Yes, breaking up bud with fingers is an option, but there’s something special about the ritual of loading a grinder with a fat nug and twisting the top to reveal a lush pile of green goodness. Not all grinders are made alike, however, just like how some sidekicks can be disappointing and worthless (see: Snapper Carr, whose schtick was being a powerless, hip teen and ended up getting kicked out of the Justice League for revealing the location of their secret hideout to The Joker) or extraordinarily badass (see: Robin. He’s Robin! Look at the spinoffs!). Below, we’ve done the work of separating the Snappers from the Robins. These are the best weed grinders you can buy.
