I think it's spelled that way. But what me and a friend got when we went to the city was a 3-Chamber grinder, b/c we smoke alot of weed and are getting tired of breaking it apart with our hands. So you grind it up and the bottom chamber lies a keif catcher and a sifter-like cover. It's like the crystals and grinded up hairs that get sent to the bottom if they're small enough. So we sprinkled a little on to a joint and smoked it, and the high was soooo much more amazing.
Anyone else do this? Good experiences?
