If I remember correctly, you can go all the way through. It should be a size between the tension screwdriver and the "large" screwdriver in width. It sometimes helps to go in the diagonal. If it is too small it won't catch the corners. Also if you have an old fork that you can bend all but one tines out of the way and use the remaining one to open it. I had one the guys I work with actually cut three off, I still need to cut the handle off so it will fit on a key ring.
