Here is a metal grinder with a kief/kif catcher on it. (top left) It has a 'shake' compartment, too. Look in the bottom. There is keif/kif there! :pimp:
The one on the right is metal...has no other compartments.
Bottom one is plastic.
I have a pic of some keif/kif I made from the grinder. Post it later. If you have real crystally stuff, it's easy. And cool. :thumbsup:
