Do crowbars give you any kind of bonus when used on doors? All I can find is the basic description in Core "This
object can be used for forcing doors and other objects open."
I dont believe they do by core. I would likely give them a +4 bonus, essentially like having another point of strength for the task or I would make it less likely to damage things within the container. So mostly circumstancial bonuses based on the situation as a character would have the right tool for the job.
