Picking a file cabinet lock with household items?

The lock is SL 120 and I was wondering how I could pick it with household items. I've tried JUST a paper clip and I was at it for several minutes with no luck. Any other methods/advice/tips?10 points to the best method for me

did you lose the key ? a office supply can replace it with the # off the lock,

Do you need to preserve the lock? If not, I recommend a drill. Just drill through the lock cylinder. If you need to preserve the lock, you need a new key anyway.
