People say this a lot but the dull knives I have won’t cut my hands around the force required to cut, say, veg. My sharp knife will cut my hand at extremely low levels of force. Also the direction the dull knives can slip is usually along the surface of what I’m cutting which would almost always be away from my hand.
The knives I consider dull will absolutely cut me if I do something dumb, and I'm much less likely to do something dumb when the blade goes straight through what I'm cutting without having to use any force.
I guess it also depends how and what you're cutting. I sure wouldn't try to julienne carrots with a knife that doesn't easily slice through the carrot.
