When I was in maybe third grade (around 2001-2002), I managed to convince my parents to get me and my brother each a CHF 55 fixed blade knife from Manufactum. Sadly they don’t sell that particular model anymore.

Made in Finnland especially for kids, full tang, thick carbon steel bladestock (you definitely wont snap it), and a robust (kiddiesize) grip lined with red-dyed donkey intestines. Came with a leather sheath.

We (ab)used them extensively and all out friends at summer camp, who “only” had Swiss Army Knives were very impressed. I even lost mine in our garden for a few years, but when I found it two years ago I polished the blade, sharpened it up and it was back in action like new. I then gave it to my smallest brother (11 y/o rn) who enjoys it very much.

If he doesn’t lose it, I am confident his children will also get to play with it.

Finding a deal like that on Amazon will be significantly more challenging. We just flipped through the catalogue and the only knife they recommended for our use case has worked flawlessly.

EDIT: It’s not for sale anymore, but here’s a picture, all though mine doesn’t have an engraved blade. https://i.pinimg.com/originals/ae/48/d8/ae48d8a31c3963e3993b...
