When I came to my job 19 years ago I was told to go to supplies and get what I needed, Swingline heavy-duty was the standard issue and I chose a red one instead of black or beige. We are still happily together.
Today it got jammed in a way I couldn't easily undo. I found this site for answers. I realized, like with all high quality products, no "little ole girl" could hurt the Swingline. I unjammed the 12 stuck staples and now I am as happy as if I'd just won the Lottery!
