I got a Milwaukee box cutter a couple weeks ago. It's primary purpose is breaking down boxes from Amazon to reuse as firestarters in my wood stove, and secondary purpose is ripping open shipping containers. It has replaced all my pocket knives, period. Nothing breaks down boxes like a box cutter. Nothing opens packages like a box cutter. I'm not talking about the kitchen or the woodpile, this is just about boxes and envelopes. One swipe and it's handled. On the rare occasion that I have to switch out a blade it takes about a minute to open it up and flip the blade around or install a new one. No sharpening needed. Not that I dislike sharpening knives, I do that with my kitchen knives all the time.
Bottom line is, if I need to shred an edge of a box to start a fire, I'm reaching for my box cutter. Not a single one of my knives do the job anywhere near as well. I got the thing free with a tape measure, so it was kind of a surprise as to how effective it was. Even better, I shred the box away from me with the box cutter, and my knives just don't do it that well. I have to go from the edge of the box IN. Safer to boot.
