Answer 3

Most likely a combination of the friction/pressure put on the blade when slicing vegetables (eventhough vegetables are fairly easy to slice, there is still a degree of friction which would dull a blade) and the acids from the vegetables (which would have a minor corrosive effect on the steel and would eventually cause the blade to become dull). At the atomic level, I'd say it's simply a matter of compression (in the case of friction & pressure). I'm not sure how to describe the corrosive effect of an acid on steel at the atomic level, but I would point out that with friction & pressure, it's a matter of a physical change vs. acidic corrosion, which is a chemical change. Since a chemical change is occurring, it would have an obvious impact on the sharpness of the blade.

Answer 4

Dull knives are dangerous. They tend to slip and that loss of control over the knife can send it into things like fingers.

Answer 5

Dull knives require more work! Who has the time??

Answer 6

With a dull knife,you must use more pressure to "saw" your way through something,rather than to Slice" quickly through the object,the real issue here is "safety."
The dull knife requires more pressure,and when it slips,is more likely to cut you terribly. With a sharp knife,you slice through easily,and effortlessly,therefore eradicating the possibility of self mutilation. Good luck!

Answer 7

I once cut myself in the pinky using a dull knife because it slipped.

I was cutting a lime and then the juice got into my cut.. OOo man it stung!

it left a cool a ss scar though!

Just use a sharp knife. its less of a hassle.

Answer 8

Well, my theory is that instead of cutting through something with ease you bear down harder and instead of cutting through you slip and cut your hand with more force. I have cut my finger very badly with a dull knife this way.

Answer 9

Are you using them to cut? Then sharps are better because they can cut more easily.

Answer 10

Sharp blades cut cleaner & do not leave such a mess.
More precision, more efficiency, etc.
