Ah, the paper clip! I never thought I'd have paperclips in my pickcase, but I can't live without them. For locks where the warding is "undercut" at the bottom on the lefthand (assuming clockwise rotation and US lock orientation) I stick a paperclip in the little cutout. This keeps the wrench from camming under the ward and jamming against the shell. Using paperclips or other more professional bits of metal is a way to even out the walls of the keyway to provide more uniform torque/tension. (And while there are bypass tools as datagram mentioned, I have used a second tension wrench as well to improve keyway grip)
