Our Damascus knives are made of carbon steel, which needs characteristic care.

Compared to conventional knives, they are slightly more “alive” and their surface changes a little with use and forms its own patina. It is a natural and fascinating process that belongs to these knives.

If you take care of your knife according to our advice, it will serve you well and for a long time.


Carbon steels tend to oxidize more in the beginning before the blade develops its natural protective layer.

Even with normal care, this can cause the knife to show signs of rust. There is nothing to worry about, it is either the beginning of a natural patina or just surface corrosion, which can be easily removed as follows:

Wash the blade with the rougher side of a kitchen sponge using detergent in warm water, dry and rub thoroughly with cooking oil.

This process may need to be repeated several times at first until the desired protective film is formed, which slows and stops the oxidation process.

Our recommendation is to grease the knife with cooking oil after each wash during the first 4 weeks of use..


For routine care, you just need to follow a few basic guidelines:

Always cut with the knife on a wooden cutting board.

Do not use the knife to cut frozen food or bones.

Do not put the knife in the dishwasher or wash it in hot water.

Always dry the knife after washing.

Once in a while, rub the blade with cooking oil.


Don’t forget to sharpen your blades regularly.

The knife can be sharpened on tools designed for this purpose – from quality sharpeners to sharpening stones.

To maintain sharpness, we recommend that you regularly wrap the knife around the leather.

If you are unsure about sharpening, leave the knife to the professionals or contact us at info@hanuljak.com.
