There's no such thing as a stupid question! I've posted a pic of the cutters I use
I'm using .010 brass so any good quality scissors from a sewing store are the best choice. I also use a pair of my old snips from work, they work good, but yes they do leave a knurled edge which you can fix with a fine file. The pair in the picture are snap-on, but a quality pair of Wiss snips from a hardware store work aswell. I also use flush cutters. You can get them from your Lhs. I use these in very tight corners, and you need to dolly the brass smooth after which can cause or will cause some stretching in your piece. Another thing to consider, especially if your cutting long pieces is that both the scissors and the snips will curl the brass as you cut. Scissors aren't as bad as snips, but it will happen. So to solve this I use my little brake. Insert your piece, line it up as if you were going to bend it, then simply score the brass with a hobby knife or utility knife, bend it, fold it back and it will brake with a nice clean edge.
I hope this helps, if there's anything else feel free to ask
