Two things real quick before I go to make my daughter lunch..

1. As is, a butter/table type knife can easily 'stab' into flesh, my uncle and aunt were 'rambo knife fighting' with butter knives back just after the first movie came out and my uncle had to go to the hospitle and get stitches (yah, I know, not the smartest thing theey ever did) so butter knives, just because they are not 'sharp' are still knives...

2. As a kid I sharpened a butter knife with a grinder in a friends fathers toolshed, then wraped it tightly in wet leather (so it would shrink tighter to the handle when it dried and wouldn't loosen up too much if it did get wet) and it made a very sharp knife that could shave hair easily, though it was thin so it was more like a filet knife then a utility knife though.
