i use whatever, but a grinder is DEFINATELY going to pull of more trichomes than scizzors. and the finer you grind the bud, the more your pulling off those precious trichs. If i really wanna control the consistancy of my bud( i like it roughly liek barly particle size wize(hehe sizewize!)), scizzors, and a razorblade and a pane of glass.

i also grind my pot ebfore i put it in a bowl fi tis possable. One of the first things i learned in science, more surface area = faster reaction time.
