Damascus steel stands out amongst popular knife blade materials for a reason. It offers incredible blade properties, giving you a stronger and more durable finish.
Yet, it remains flexible enough to deliver outstanding cutting performance compared to metals such as stainless steel or carbon steel.
Nonetheless, Damascus steel may hold its drawbacks. For many prospective users, the main question remains – does Damascus steel rust?
This in-depth Damascus steel guide can help you figure out whether or not your Damascus steel knife is susceptible to rust?
Does Damascus Steel Rust or Not?
Damascus steel can rust if not well cared for. The material combines high carbon steel (steel contains iron) content with smaller amounts of chromium and other alloy elements. This formulation makes it prone to rust and increases the need for special care to protect its beauty and integrity.
However, with the utmost care, you can easily shield Damascus steel from rust. Moreover, if you ever notice rust build up on Damascus steel, there’s a way to remove it.
What Does Damascus Steel Mean?
Damascus steel refers to a special alloy made by forging layers of stainless steel and soft high carbon steel. To complete its fabrication, the forged layers soak in an acid bath to produce a beautiful wavy pattern, which the steel gets its name from. During the acid bath, the carbon steel is eaten away to form a unique pattern.
What Makes Damascus Steel So Special?
Damascus steel stands out for its appearance and functionality. It features a unique wavy pattern that boosts its beauty and appeal.
Moreover, many people favor Damascus steel for its incredible robustness, flexibility, and ultra-sharp blade edge when used on knives. If you want to know more about it you should read this in-depth guide are Damascus steel knives worth it or not?
Damascus Steel vs Stainless Steel – Which Is Stronger?
When it comes to Damascus steel and stainless steel, there’s not much difference in their strength. Typically, Damascus steel uses nearly similar materials that go into making stainless steel alloy. Therefore, for the most part, Damascus steel holds the same strength properties as those of stainless steel.
In fact, some knife makers choose to combine the two materials to fabricate even stronger and more durable blades. For example, many knife makers use Damascus blades that integrate a VG-10 stainless steel blend.
Damascus Steel vs Carbon Steel – Which Is Better?
The choice of whether to go for Damascus steel or carbon steel highly depends on your preferences. Both materials offer superior edge retention and sharpness.
However, carbon steel tends to be cheaper and stronger (sometimes). On the other hand, Damascus steel has a more flexible profile and aesthetically pleasing appearance.
Why Is Damascus Steel So Expensive?
Damascus steel costs more compared to other materials like stainless steel or carbon steel due to the work, time, and material used in its fabrication. Remember, Damascus steel features layers folded as much as 32 times.
Therefore, the skill, time, and choice of materials significantly increase its cost. However, you will find here an in-depth guide about why is Damascus steel so expensive?
Does Damascus Steel Need to Be Oiled?
Damascus steel requires oiling to protect it from rusting. Lubricating its surface with mineral oil or wax protects It against moisture build-up and contact with oxygen, helping prevent rust build-up.
Applying oil on the surface of Damascus steel also helps to maintain its etched beauty produced by its waxy pattern. Oils like castor, coconut, and paraffin do a great job of lubricating Damascus steel.
The Common Causes of Rusting in Damascus Steel Knives
The primary contributors of rust in Damascus steel knives are exposed to moisture and oxygen. When dissolved in the moisture/water, an oxidation reaction occurs, causing rust formation on the Damascus steel surface.
Here’s how Damascus steel becomes susceptible to moisture build-up;
- Leaving the knife uncleaned and exposed (for example on the sink) for long periods
- Poor storage (storing it on the sink or dish rack instead of a knife block)
- Not lubricating your knife with wax or oil after cleaning
- Poor handling of the knife can cause scratches or scrapes which create an ideal zone for rust framing
How to Remove Rust From Your Damascus Knife?
You can remove rust from Damascus steel knives using various methods. We’ve shared key easy ways to remove rust;
Using Citric or Acetic Acid
The citric acid found in lemon juice and acetic acid in white vinegar (white vinegar is better since it’s non-staining) effortlessly attacks rust and removes it from Damascus steel.
Here’s how to use these liquids to remove rust;
- Pour lemon juice or warm white vinegar into a dish
- Submerge the knife into the dish and soak it for about five minutes
- Next, remove the knife from the dish, wash it with clean room temperature water, wipe it dry, lubricate it with oil, and it should be ready for use
Using a Potato
Potatoes contain oxalic acid, a similar component found in cleaning products. The acid is quite effective at dissolving rust built up on a metal surface.
Here’s how you use a potato to remove rust from Damascus steel;
- Hold a large potato in your left hand and use your right hand to push the cutting edge into the potato
- Leave it in this position for at least 24 hours or longer
- Once done, remove the blade and wash it with clean room temperature water and mild dish soap to remove any rust residue
- Wipe it dry with a clean kitchen cloth, lubricate it with it, and it should be ready for use
How to Prevent Damascus Steel From Rusting?
While Damascus steel is susceptible to rusting, the good news is that you can prevent it entirely.
Here’s what you can do to prevent Damascus steel from rusting;
- Avoid acidic food items like apples. However, if you absolutely have to use your knife on them, immediately clean it, wipe it dry, and lubricate it after use.
- Protect Damascus steel from moisture: After each use, clean the knife with clean water and mild dish soap and wipe it dry. Next, lubricate the blade using wax or mineral oil before storing it in a knife block. As you wax or oil the blade surface, you will also be protecting the pattern.
- Clean out any rust: If you notice even small spots of rust, you want to clean them out. Use a q-tip or vinegar to spot clean the rust from the blade.
- Maintain the blade edge: A dull bald is also quite susceptible to rust than a properly sharpened one. So, you have to maintain the practice of honing and sharpening your knife as required.
Undoubtedly, Damascus steel does rust. However, this only happens with poor care and maintenance. With proper care and protection, you can enjoy the full benefits of Damascus steel without worrying about the rust build-up. As a general rule of thumb, remember to clean your Damascus steel knife blade with mild soap and clean water after every use.
Additionally, don’t let it lay wet. Instead, wipe it dry with a clean kitchen cloth and lubricate it with wax or mineral oil to fully seal it and protect it from moisture build-up and oxygen.
Moreover, always store your knife in an appropriate knife block. After all, moisture, oxygen, and poor storage (leads to cracks and chips) of Damascus steel are the key factors of rust formation.
