"A dull knife is pretty safe for most people."
While your point is true, I want to object to your metaphor. I object for safety purposes. In fact, a dull knife is more dangerous than a sharp knife for most anyone who needs to cut things.
You need to press much harder with a dull knife and sometimes even to saw down into the object. You may even need to get a firmer grip on the object you're cutting to counter all that force. Those are very dangerous behaviors. A sharp knife that cuts easily is much, much safer.

- peterwwillis 13y agoNot true. A dull knife is dull; it's not dangerous at all because it basically can't cut anything. A half-dull or half-sharp knife is dangerous. It can cut, but you don't know how much, and variations in the blade make it unpredictable, in addition to the behaviors you defined.
- dllthomas 13y agoI would describe a typical kitchen table knife as a "dull knife", and trying to use that for tasks to which it is not suited can certainly lead to injury.
