Sharp Knives Are Safer Than Dull Knives

chef's knife, over 30

Sharp knives aren't actually as likely to cut you as dull ones. Because a sharp knife easily slices through food, you only have to apply a small amount of pressure when using them. This means that you're more likely to cut the item you're intending to cut, and not your hand.

Dull knives, however, can't cut through food easily, and often cause injuries when resistance between the dull blade and the food's surface suddenly gives way, at which point the knife flies out of control. Since you have to use so much pressure to cut with a dull knife, they often cause deep cuts and gouges, as opposed to the minor nicks a sharper knife might inflict. Keep your knives sharp and hone those skills for maximum safety. And for more tips on becoming a culinary master, check out these 5 Easy Kitchen Moves.
