knifers = take two knives (i use butter knives) get them red hot, then take a small ball of resin, hash, weed, whatever and put them (extremely carefully) between the two knives, squish the knives flat, and kind of move them a bit, not much tho, it will make a huge plume of smoke come up, you can be ballsy and use nothing, but it's safer just to use the top half of a 20 oz. to catch the smoke. it's a very effeective way (tho difficult) of getting stoned, it hurts like hell (harsh) but it will get you high as fucking hell using as little weed as you possibly could.
