That would be a time and worksavers...Looks like a way to open their packaged products?

Not just a letter opener, but a paper cutter in general. They used to sell them at the R/C hobby shop for cutting covering material (Monokote, etc.), and they were also sold for cutting gift wrapping paper. Never heard of using one as a letter opener but I guess it would work fine.Yep, can confirm the letter opener. We had them around the office when I was a kid. They were fast, and they would save you from getting paper cuts if your job was opening letters all day long. I never saw the other two around that office.
