knifing never works well for me with bud, you gotta konw what you're doing before you do it, otherwise you're going to end up fumbling around with the bud til the knives are almost too cool to produce the smoke, and by then, it's just wasted bud, because i'll be damned if you're going to get half burnt/toasty bud to stick on those knives....

it works alot better for resin, hash, oil, w/e.. because those things stick VERY well to the blade and there's no juggling act, just touch and smash... i like knifing because the hits it gives sometimes are ridiculous and just wreck the shit out of you... but for the most part, it's not worth the effort... when there's so many more laid back, easy, STONER FRIENDLY methods of smoking weed, even some that rival hit/conservation of knifing, gravity bongs being one of them...
