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: -The Slice micro-ceramic-blade tools are ideal safety knives for cutting plastics, paper, or any other thin material. Because the tiny blades are extremely unlikely to penetrate skin, these tools are favorites with adults who have impaired motor skills or limited dexterity, and those who work with children.

Detailed explanation-3: -When knives begin to dull it is usually a result of the sharp cutting edge rolling over, not actually being dull. A steel’s primary function is to straighten the rolled edge, allowing the rolled part to cut cleanly again. Using a steel is very simple and fast.

Detailed explanation-4: -A sharp knife has lesser contact surface area than a blunt one, so, a sharp knife applies a greater pressure when used for cutting. This is why it cuts better.
