How to care for your Damascus steel blade. It is carbon steel (1095 / 15N20 Damascus Steel) so extra care should be taken.
With its historical reputation as the metal used for the best swords over hundreds of years and its distinctive wavy design, Damascus steel is a beauty to behold. So with that quality blade–especially one that has intricate etchings–comes special care. Here are our tips on how to care for a Damascus steel knife, in order for it to maintain its beauty and use.
1. Lubricate carbon steel Damascus blades.
The pattern in damascus forged completely through the entire Damascus blade. The steel’s unique pattern is only truly revealed with etching an acid wash during manufacturing. This etching causes the different oxidation levels to show dark (oxidized) and light/shiny patterns on the blade (resisting oxidation).
Most hand forged damascus blades are made of high carbon steel, which means that they have a relatively low amount of chromium in the steel. Carbon steel and carbon steel damascus can rust when not cared for properly. You will need to make sure the blade remains clean and dry in order to prevent rust or discoloration.
After cleaning and drying your knife, you should lubricate it with a wax to prevent moisture from affecting the blade. We recommend Renaissance Wax (an archival-grade museum wax), because it will keep your knife rust-free and maintain its etched beauty.
2. Avoid abrasives.
Avoiding abrasives–rough cloths, metal polishes, steel wool, etc–is important to maintaining the look and quality of the blade because if you do use an abrasive or metal cleaner it will remove the etched oxidation that you want on a Damascus knife to show the pattern.
3. Be mindful of when and where you use your Damascus blade.
A carbon steel damascus blade is especially susceptible to damage when used on acidic foods (fruits, for example), in wet, humid environments, and for field dressing game. These uses and environments can remove the etching of the blade.
When you do use damascus, remember to wash and dry it immediately, taking care to not rub the blade roughly. Using a microfiber or cotton cloth to dry it, the softer material will not wear the blade.
4. Store it properly to keep it rust-free.
When not in use, it’s important to keep the Damascus steel knife in a dry interior environment, where it will not be affected by extreme moisture or temperature changes. After cleaning and waxing your knife, storing it in a box or padded zipper case, your knife will keep well.
When out in the field with your knife, make sure that you don’t keep it in a wet environment for long periods of time. Don’t store your damacus knife (or any knife for that matter) in a leather sheath – acids and chemicals are used to tan leather and can lead to oxidation over time due to the normal moisture found in the air.
In addition, keep an eye out for a wet handle: the moisture from the handle can also rust the blade, so keeping the entire knife dry is important. We strongly advise against using a dehumidifier bar if you are storing damascus knives with natural handle materials; especially in a closed safe or storage compartment. Extreme low humidity is a hazard for ANY natural handle material (woods, stag, etc) and will likely cause cracking or separation. Humidity does not affect synthetic handle materials.
