Photos I've just found this gigantic thing while dusting during the lockdowns. :-)

It happens to be my long-forgotten first knife, probably received at age 5 or 6. It's 4.5 cm long, with a 3-cm blade, built fully of stainless steel - or possibly with an aluminum handle.

(The blade is scratched like a hen's playpen, because when one goes to explore abandoned WW2 bunkers with one's buddy at age 8 or so, one may tend to try "sharpening" the knife on old military concrete... I would not polish it, though, since each of those scratches was an adventure. )
