Maybe it's just me, but I'd rather teach how to use a knife safely? And a cut from a blade is a lesson to be learned, hopefully only once.

Edit: Oh and if anyone's looking for the tool name, it's called a nibbler. This one is just table-mounted, there are power tool and unpowered versions ofc.

You can introduce this way before you can trust a kid with a knife sharp enough to cut cardboard and they can use it way more independently.

Exactly, you're basically telling them you can't build stuff until you're 8+. Which coincidentally is around the age they'd lose interest

A cut from a simple blade (that can't chop your finger off) can be anything from easily healed to going through just the right part to limit the dexterity for life if you're unlucky. There's lots of time to learn using a sharp knife when they have great fine motor skills already.
