I designed a cardboard cutter that turns boxes into free cat scratchers

Also good for composting and making room in your recycling bin

You’ve designed a niche solution to a problem that doesn’t exist.

Use a box knife. Or, for a more versatile tool, get a Morakniv Companion.

This looks a lot like trolling. The community here certainly doesn’t seem to care for it.

I don’t like what you’ve said so you’re a troll. We don’t serve your kind around here.

SMRT.
