First time my Dad ever let me hold a pocket knife, I lasted all of about 60 seconds before I accidentally closed it on my finger. It's almost a universal truth that a kid's first knife will draw blood within the first 24 hours, if not sooner. Best to just have the bandages ready and hope it's not too bad. Glad she's okay.
A couple years ago, my wife gave me a really nice modern folder for my birthday. Next time I was over at my parents' house, I pulled it out to show Dad. After a minute, I see his hand go past the tip, and then he immediately sticks his ring finger in his mouth. I said, "Really? Did you really just cut yourself on my brand new knife? Let's see, what would you have said about that when I was a kid?" He said, "Shut up, boy, and get me a Band-Aid."
