Why does a knife have a jagged edge?

Serrations give the blade's cutting edge less contact area than a smooth blade, which increases the applied pressure at each point of contact, and the points of contact are at a sharper angle to the material being cut.

What are knives with ridges called?

Bread knife

Its serrated grooves are specifically designed to cleanly slice through bread without crushing it. Bread knives can have a classic knife handle or may have an offset handle which keeps the chef's knuckles from knocking the bread while slicing.

Why do knives have serrated edges on the top?

Serrated edges are blades that have some kind of toothed or saw-like edge ground into the cutting surface. These are intended to be used much like a small saw with a back-and-forth motion. They're great for cutting through belts and ropes, fabric and various other textured materials.

Why do knives have a hole in the top?

The hole on the heavy-duty blade makes cutting through bone easy. The hole enables you to hold the upper part with your fingers. As you reinforce your grip on the handle, you are able to pull the blade free.

What are the grooves on knife blades for?

Gravity takes care of fluids and suction is going to happen anyway. Instead, blood grooves are worked into a blade to reduce its weight without sacrificing length. This helps a knifemaker or designer achieve better balance. Blood grooves may also be used for looks, since people think they're badass.

Why are some knives wavy?


This is mostly due to the blade's razor-sharp crests, which can slice through material without pulling at the individual fibers like a toothed blade might.

Why are some knives scalloped?

The purpose of these scalloped-edge blades is to prevent food from tearing and produce intact slices of food. The scallops allow the blade to slide past the food without catching or bending it. This helps moist or clingy food to fall away from the blade.

Why is a knife shaped the way it is?

The shape evolved so that the knife can efficiently perform the rocking motion used in chopping, where you bring the knife blade down to the food starting at the tip and rolling it to the heel. The tip of the knife doesn't leave the cutting board.
