My boss had a habit of buying office supplies haphazardly. When I took over as office manager I noticed that we were going through a lot of staplers. The only ones that we didn't have to replace were the 747. From then on I only buy the 747. And when someone leaves the company, I make sure that I put their stapler back in the supply closet so it doesn't get lost and I can reissue it to the next new employ. They cost a bit more that other stapler, but, they hold up and do not have to be replaced very often. I just recently replaced my old red 747 with a new black 747. I had the red one for the last 13 years and it was used when I got it. It still works but it gets jammed. I think I dropped it one to many times. I keep iit in the closet for a spare.
