I’ve done this with a new and thus terribly sharp knife. I’d bought it for my mate, so when I knocked it off the bench my reaction was oh no! damage! catch!

The kitchen looked like a scene from Kill Bill. Perfect blood spray in an arc across the wall.

This mate lived with me at the time. And he was a nurse. He came home from his shift about half an hour later and I told him, sorry man, but you’re driving me straight back to the hospital.

I’m lucky to still have total use of my right middle finger.
