Coloring Damascus knives: How is it made?


Do you know that program? How is it done? They need a continuum of those things for the knife industry. On a daily basis here at Blade HQ, we scratch our heads when we see the incoming products and ask ourselves: "How did they do it?" One of those cases is Damascus. We have some answers about this, but before we dive into the colors, it is important to understand a little about how Handmade Damascus Steel Folding Pocket Knife steel is made: In short, several common steels are welded and attached to a metal handle. The artisan throws the material of the bar in a forge for a while, then removes them and begins to mix the steels by means of a hydraulic hammer or a forging press.

But what about Damascus steel colors? Particularly, how does the Damascus family create patterns and designs in their ridiculously wild personalized damask knives? It was surprisingly difficult to find something about how Damascus is made of colors. Fortunately we know the people of the industry, so we went directly to the source and called Damascus. This family of knife makers is extremely talented and has turned Damascus into a science, a feat not surprising, considering that Rainy Damascus has been in the industry for 22 years.
There are different ways to color Damascus, but this is how it is done in the manner of Damascus.

Coloring process of Damascus steel knife

Stainless steel does not acquire color when heated, so Damascus uses high-carbon steel with the addition of nickel for its colored Damascus. Nickel is ideal to use because, although the high carbon content changes color when exposed to high temperatures, nickel does not. Instead, it will turn golden in color and create a beautiful contrast to the newly colored steel.
After the Damascus blade has been thermally treated, it needs to be polished and then cleaned with soap and water. Once the blade is dry, it is ready for a color change. Recently, in Damascus, the use of a process of water bluing to salt blue was changed, and a propane turkey fryer was used for this part. The fryer is full of salts and is heated to about 560 degrees.
Then, the blade is dropped into the fryer until it reaches the desired color. This type of steel can generally vary in color from bronze to light blue.
The final result of bluish salt is a truly unique and beautiful blade.
