But that's the thing, we _do_ cut onions with our dull knives. And it's never been a problem.

To be fair, you also will cutting onions with a sharp knife.

>> Try cutting onions with a dull knife. You will cry yourself out of the room.

Have you tried that or are you speaking in principle only?

Not the person your asking, but can confirm: a dull knife releases much more of what makes you cry than a sharp one when cutting onions.

I should also ask you then: have you tried that, or are you speaking in principle?

Sorry for the slow reply; it's noticeable in practice. I'm pretty sensitive, and it's usually a good indication that it's time to sharpen knives when I start crying a lot. Sharpening generally improves my onion-cutting experience, unless it's a particularly pungent bag of onions.
