I recommend the cutter bee scissors. They are excellent for getting in those teeny tiny spaces, they open and close easily without sticking, and they are SHARP! I dropped mine the other day and they stuck straight into my hardwood floor like a dart. I love them. Cutter Bee Scissors
I used to love my cutter bees for this, but then discovered Fiskars softouch. They really get into those hard to get places. I have several friends who like these as well, and have told me that their new favorite is the Tim Holtz scissors.
more than just the scissors themselves, it is important to hold the scissors correctly. After working in the operating room, I found that it is important to hold the scissors so that your thumb is in the top hole and your 4th (ring) finger is in the bottom hole and the tool rest on the third and and stretched out 2nd finger. This gives you more control of the tool. Also, try to turn the paper more than you turn the scissor itself.
