Can one open a combination lock without knowing the combination?

Yes. I've seen a floor safe opened (with permission from owner). One
pool cue rested against the ear gently (cue tip to dial area) as the
other persons turned the dial, try a wooden dial or long screw driver.

Many years ago, though!
