Thanks for this, which one specifically? My 5 year old watches cardboard project videos on YouTube and loves building. We even got him a hot glue gun which he uses on his own, after a couple of burns he’s very adept with it. Yes I tried to dissuade him but he’s very persistent!

We have a few of #2 we got from Amazon. You can still cut yourself but it's more of an abrasion than a laceration. It's great when you can find real tools for your kids to use and explore their ideas independently.

I have one of the #2's. It's certainly possible to cut yourself. I actually cut myself on purpose just to be sure it was safe, and it wasn't too bad ;-) It was an actual cut, not an abrasion, but not deep. I've gotten myself on accident a few times too. Never too badly.
