I'll make you a sponsor offer you can't refuse...
This is a pic of receiving an order of Penne noodles, 10 pallets worth. So yeah, stocking and receiving are a part of the job. Lots of cardboard going in and out of restaurants.
Still doesn't really explain how you're supposed to cut the cardboard. You cut the tape at the side and you can tear open the top of the box... if you want to break down the box you do the same at the bottom. I actually did a few summer job at a wholesaler where we did nothing but stocking shelves and we actually never cut a single piece of cardboard. When you only cut the tape a simple box cuter lasts you for ages... If you really insist on cutting apart boxes scissors work a lot better than any knife.
I can see why knife afficionado's like to have fancy pocket knives, but I just have difficulty seeing the 'need'. It's not like you're using it for survival purposes (for which a folder would suck anyway). It feels a bit like trying to find a use for the toys you want/have instead of a use-driven search for a tool.
