Guns, Dogs and Blades QnA

My boy musta been 8 or 9 when he wanted to buy a knife
I told him fine, but he'd better be careful because they are sharp

We get home and I go to take a shower
About 5 minutes in I hear him holler "dad, do we any bandaids?"
I've always accepted the concept that a sharp knife is safer than a dull knife.
