So I just bought a space case (grinder with a kief screen)...how do I get the kief?

[tootsie roll]

out. Like once Ive ground tons of weed and have a thick layer of kief at the bottom...whats the best way to scrape all the kief out and get it into a pollen press or even just into a joint? any suggestions? any prior experience?

You could use a spoon, use it downside up or just the tip.
