OP here. Apparently this requires more explanation than I thought. The stapler was jammed so I opened the top to see if the staples were stuck. When I went to close it, the top took a lot of force to close again. My hand slipped and it sent a staple into my finger. It was an accident. I wasn't "testing it out on my finger." At the time, I was in school. I was using the only stapler in the library and it's not like I could leave school in the middle of the day to "go buy a new one." Have a little more faith in me.
