Maybe you do it with great care, David, but if I'd sharpened that sucker (it's a new one to me) she'd still be wearing the band-aids the way she did it. I think the most unsettling part was when I politely asked her to stop and she just laughed and kept going. Again, I should never have handed it to her in the first place because then my baby was out of my control.
I'm going to remember this later in life when I have children and people ask to hold them . . . . .
(and personally, I take shavings off my fingernails to test knives, or shave a bit of hair if it looks like it'll do it.)
