Lasers?
The OP could be thinking of making Halloween prop or costume, or trying for something more epic.
Sadly, the Box wars were discontinued.
This is what we use at work. They are surprisingly useful. However, I need a new one almost every shift as they dull rather quickly. I’ve taken to attaching them to my wrist with a system of rubberbands/hair ties. I wear heavy gloves in the cooler, so I have trouble fishing them out of my pockets, and if I put them down I lose them. Every. Single. Time.
It seems inefficient to have to replace the entire knife that often though if injuries are reduced, maybe it’s worthwhile?
The nice thing about the cheap disposable box cutters is that you can have a dozen or more located in strategic places around a work site and a big box of new ones for replenishment. Something used so frequently inevitably finds its way inadvertently out the door in someone’s pocket, tossed with a pile of discarded cardboard or just mislaid. We buy them in boxes of fifty.
I don’t know, but we’ve got a pair, and they’re AMAZING. We got some of those and some duct tape, and our kids made all sorts of cardboard creative things- tanks, airplanes, trains, forts, dioramas, you name it.
The serrated cardboard knife is good as well; we’ve got those too, and the kids use those as well.
Heh, we’re not really building anything right now, and this isn’t a “need answer quick” situation.
Last week, we did cut out a prototype catio gate out of cardboard with some regular scissors and THAT was a pain. We both thought “we should get some box cutters”, and so I said ok, let me look online and see what the last 20 years has changed in terms of their designs and options..
I did NOT expect to find a whole rabbit hole to dive into. I was surprised by both the number of options, and by the lack of clarity around how they are different and which is better for what kind of cutting. I guess I naively assumed that in 2025 cutting cardboard would be a solved problem, but boy was I wrong…
I found this site after the thread was created: Index – scienceofsharp
It is a deep, metallurgical dive into how knives work, using a combination of scanning electron microscopy, materials science papers, and math to explain the science-y tidbids of cutting. Unfortunately it doesn’t focus on cardboard and stops short of analyzing cutting geometries and electrification.
I guess this thread would be the poor man’s version of our 2008 What's the best metal to use for making a sword?
Now that there have been lots of helpful replies on the various types of cutting tools, I’d like to address this part of the OP
My understanding is that most paper products contain kaolin, a powdered clay, and these tiny but hard mineral particles cause metal and ceramic blades to dull faster than one might expect given that the bulk of the material is composed of plant fibers.
I’ve been using a serrated bread knife for years.
Yep, Stanley Knife for the win, and if neat, clean cuts matter, change the blade before it really feels like the blade needs changing.
The segmented-blade box cutters will do in a pinch, but I find that the blade lock, whilst it is good at preventing the blade from pushing back inside the knife, is not always effective at preventing the blade from being pulled out of the knife, if it is gripped by a thick material such as corrugated board.
Wood (from which paper and cardboard are made) typically contains some naturally-occurring silicates and these too contribute to blunting of tools.
