Forging Process

 

Knives are forged using avariety of techniques, each providing unique blade characteristics.

 

FRIODUR ICE HARDENING PROCESS - Many Henckels knives are crafted using the special patented Friodur Ice Hardening Process. This process involves the steel being heated up to one-thousand degrees Celsius then cooled to below minus seventy degrees Celsius and finally reheated to above two-hundred-and-fifty degrees Celsius.

The Friodur process results ina n extremely strong and sharp blade that maintains its edge for longer than traditionally crafted blades.

 

SIGMAFORGE - Many Henckels knives use the patented Sigmaforge process, whereby the knife is forged in a single piece of steel. This process creates a long lasting durability, flexibility and elasticity as well as a superior cutting edge for the knife.

The Sigmaforge process involves applying temperature in a controlled fashion, heating only the portion of the 'blank' that is needed to be worked; this not only prevents detrimental influences on the quality of the steel but also requires 70% less energy than a traditional forging.

 

FORGED KNIVES - Forged knives us a traditional manufacturing process whereby hot metal is hammered into dies. Most of us would recognize the forging process as a modern update of the old fashioned blacksmith process, with red hot metal being hammered into the required shape. Forged knives tend to hold their edge longer than stamped knives and are also easier and faster to sharpen.

 

STAMPED KNIVES - Stamped knives are cut from large sheets of stainless steel, like cutting gingerbread men from rolled out cookie dough. This results in a flexible, light weight knife. Stamped knives tend to not hold in edge for as long as a traditional forged blade, so may require more frequent sharpening. Stamped knife manufacturing is also a less time intensive process, resulting in a more affordable product.
