Steel wool and Chore Boy are both exceedingly poor choices, steel wool because it's too fine and tends to catch fire and get stuck together quickly, Chore Boy is bad for the same reason that it's popular, that being that it's made from copper, which is much easier to tear with one's fingers than steel but also produces extremely toxic fumes when heated. The best screen to use is either five to ten large steel pipe screens laid on top of each other and pushed into the stem or a chunk of heavy gauge steel scouring pad about the size of the first section of one's pinky finger, burned black, compacted and put in the business end of the stem. The best lighter is a barbecue lighter, a regular cigarette lighter is fine too but has a tendency to burn the fingers. One might also use a cannabis pipe or bong or "crack bong" consisting of a foil bowl over the neck of an empty bottle and a pen tube through the side to inhale through, fill the bowl with ash or finely ground cannabis, put your crack on top, melt into ash/cannabis, light, smoke away, this was my preferred method.
