Cutting carboard with scissors? It can be done, but it’s a chore amd the results are poor. I wouldn’t wish it on school children.
Your tools probably suck.
Any knife and straight edge is faster and easier. Any warehouse worker knows this. Any compost bin is better than cat scratchers. Any environmentalist knows this.
For scissors I recommend Fiskars titanium nitride. Just yesterday they gave me a nice curve in 1/16th aluminum. Cardboard cuts like a hot knife through butter. And, I bet they cost less than the materials used in the tool in the OP.
Box knife reco: any metal housing without an auto-retract safety feature but with a retractable blade
Well, I don’t think we’re on the same page. I’m not really into OP’s design, but I also don’t think that school children use Fiskars scissors.
Don’t know what’s wrong with cat scratchers. Cats love them, and if you use an environmentally friendly glue you can still compost them later.
I do have good tools at home, but I trully appreciate your recomendations - that’s rather wholesome of you, thanks.

For adults: box knife with a jig consisting of a fence and stop block
For children: auto-retract safety knife and add a second fence to keep the blade enclosed
A child learns nothing but dependance on stupid gadgets from the device in the OP.
