What Is a Serrated Knife?

A serrated knife is known for its unique tooth-like edges. This blade is quite similar to the ones that are used on saws. This kind of blade is also referred to as a toothed blade. You will also find serrated scissors on the market.

A serrated blade comes with a cutting edge. Due to its tooth-like design, it has a lesser contact area in comparison to a smoother blade, and the applied pressure at every single point of contact with the food is much greater.

Even the points of contact are at a much sharper angle to the material that is being cut. This results in a cutting action that involves several small splits in the surface of the food, which serve to cut the food along the line of the knife.

This kind of knife is great for cutting or slicing food like melons, tomatoes, and bread as these tend to have a tough exterior and a soft interior. Using a serrated knife on such foods will cut through the tough exterior with ease while not harming the soft interior.
