In the 90s I was taught knife safety before being given blades. Had to pass a test before we were given them. Seems pretty reasonable to require that to handle something that could kill another person so quickly, easily, and even by accident.
Also much cheaper than casts, physical therapy, and possibly permanent damage. An ounce of prevention and all that.
My 5yo got plastic kitchen knives for her birthday which, while pretty dull, are still good enough to go through zucchinis.
A test wouldn't work here as she can't read yet (not full sentences at least).

You can teach kids how to safely handle and use blades. This reduces -but does not prevent- accidents... and some kids will handle them carelessly despite the training. [0]
In other words, the fact that a kid on the trip was cut by his friend doesn't mean that there was no blade safety training prior to the trip.
