It lowkey reminds me of Overlord how even the rubbish items that the MC gives to regular people are still, like, items of immeasurable value for common folk.
Like, this catgirl is probably thinking that this knife is a priceless weapon of immeasurable destruction, but the MC is just like "man, that was a good warm-up for my first blade. I can't wait until I'm actually good at this" (it also looks so crude like a box cutter)
