Yes to additional mindfulness and knowledge. I know that sharp knives are safer for those with a modicum of knowledge, but I have to wonder about the general public, or those who think they know a lot about knives but in fact don't know much. I handed my Opinel (thanks, Baryonyx!) to my idiot cousin, as he had just shown me his overpriced Chinese hunting knife. I warned him twice not to thumb the edge, as I had just stropped it. He thumbed the edge. It took a moment, and he seemed pretty surprised to see blood running down his hand. So it would be my guess that a sharp knife is safer for sharp people.
