How is a knife blade processed?
The blade, the most important part of chef knife, is usually made in two different ways: forged and stamped.
“Forged” blades go through a complicated multi-step process and are usually made by hand by experienced forgers. This makes forged chef knives more expensive than stamped knives.
The process of creating a forged chef knife is to heat the steel to a very high temperature, beat it into shape, and then grind and sharpen the blade.
Usually, forged knives are full-tang, meaning the blade in the knife runs from the tip of the knifepoint to the very end of a handle.
“Stamped” blades are made in a less complicated way than forged blades. Stamped blades are cut from cold steel, heated, ground, and sharpened.
When you choose a high quality chef knife, consider purchasing a "forged" blade to insure the highest quality.
