No matter how careful you are
It's still easy to cut yourself while slicing bread. Yesterday, when halving one of my Pane a l'Ancienne from TBBA, I put my hand on top of the loaf, and sliced along the side, like I always do. It removes the possibility of getting the knife in the palm of my hand. Instead, the knife skipped on the (beautiful) crust and right into the pad of my middle finger.
I managed to keep the blood off the bread! :) And boy, was there a lot of blood.
I served it at a friend's party, and it was the talk of the room. Nothing trumps fresh bread!
