As Pointless as a Dull Knife
There is nothing worse that attempting to cut vegetables or meat with a dull knife. Not only could it potentially lead to losing a finger, it also means wasting time because it is going to take you twice as long to cut through a piece of chicken as it would with a sharp knife. The expression as pointless as a dull knife is not only a witty observation, but could not be truer in the fact that a dull knife does not have a point. If you find that your knives are becoming dull, you should take them to a professional knife sharpener. This is because some knives need to be sharpened a special way and with every knife, if you sharpen it incorrectly, you can ruin the blades and will have to buy a completely new knife to replace it.
