it was probably an idea at some point, and the knife on the machine was very sharp and made easily openable boxes, but I guess there was a complaint about the integrity of the box, or it having holes, that over time they let the machine(s) blade go dull so the thing is barely useable. Might also be due to a different cardboard composition than the original one, but I think it's mostly a dull blade on the machine, there would probably be complaints if they put in a new blade.
