I should never be allowed to pick up a knife. Ever.
I’ve had more cuts on my hands - once I cut the pads off of two fingers, had to drive myself to the ER - got there, asked the guard where I could park, he took one look at the towel wrapped around my hand and said, “Hon, you go on in - I’ll park your car and bring your keys to you”. There wasn’t even anything they could stitch, just had to bandage it up.
My boss at a deli had a cut like that and they did a graft with skin from his wrist. He hovered like a mother hen whenever I used a knife after that, until I reminded him who got injured.
