I find scissors to be a hinderence when cutting up ganja.
If it's condensed and has the stem in the middle of the bud, you either have to apply an enormous amount of pressure, but moving the blades a tiny amount at a time, or just cut it fast and watch the piece of bud fly across the room.
I do the first examply, apply a lot of pressure but move my hands a minute amount at a time and very slowly, otherwise the scissors just cut through and the bud flies off, like when cutting finger nails.
