Discover the Functionality of Knives with Holes in the Blade

1. Holes Make Knives Lighter

We commonly use kitchen or chef knives to cut veggies, fish, meat, and many more. These knives usually have a thicker blade that makes the knife heavy. Holding these knives for extended periods can exhaust your wrists or arms.

When holes are made in knife blades, some of the blade material is removed, reducing the overall weight. So you can comfortably use the knife for longer without getting tired.

2. Holes Reduce Friction

Friction happens when two surfaces rub against each other. For example, when you cut something with a knife, there will be friction between the cut surface and the blade. So, you need to apply more force to the knife to cut that thing.

Can Holes Make Knife Blades Weak?

The answer to this question depends on several conditions. 

Can Holes Make Knife Blades Weak
  • First of all, holes won’t weaken knife blades significantly if the blade is thick and made of high-quality material.

The blade can be damaged if you apply too much pressure on the knife. So, you should carefully choose a knife with holes in the blade.
