I have a roll of window screening that I take over a large container and I'll usually take 1/4 brick [pound] and just scrape the crystals off of the bud by scraping it over the screen for a few hours, and that leaves you a nice fat bag of keef, which if you compress will turn into little keef buds, excellent for smoking but very harsh smoke. As for the spelling, it can be Kif, Keef, Kief, or Keif, depending on which part of the world you live in, its spelled diferently. As a side note, Kif also can sell for 10x the amount of normal pot. Have fun.
