Detailed explanation-1: -A dull blade is actually more dangerous to use than one that is sharp. Here’s why: A dull blade requires more pressure to cut, increasing the chance that the knife will slip with great force behind it. A sharp knife “bites” the surface more readily.

Detailed explanation-2: -While one certainly needs to take care when using sharp knives, a dull blade is more dangerous than a sharp blade. When a knife blade is blunt or dull, it requires more pressure to cut, making it more likely to slip with the increased force behind it and cause an injury.
