Titanium knife blades are very practical and aesthetically pleasing. Over the last few years, their popularity has just boomed and they are becoming more and more popular.
Whether you own a knife with a titanium blade or if you are thinking about getting one, you might be wondering: are titanium knife blades magnetic? I had this same question, so I did some research and this is what I found out.
While titanium itself is non-magnetic, most titanium knives have strong magnetic properties. This is the case due to the majority of titanium knives being made of magnetic steel and only coated in titanium. If a knife blade is made purely of titanium, it would display very weak magnetic qualities.
This might seem a little bit confusing at first, but I promise it’s not once you begin to understand a little bit more about titanium knives. Below I will go into a lot more detail regarding the magnetic properties of titanium knives as well as some common questions regarding them.

Are Titanium Knife Blades Actually Magnetic?
Just like most things in life, there is not really a direct answer to this. Titanium knives are technically magnetic most of the time, but titanium itself is not magnetic. I know, it’s confusing. But bear with me and I’ll explain everything you might want to know about this topic.
So in the end, I guess the best answer to this question is: sometimes.
You might think this is kind of like a cop-out, but I promise you that it’s not. Let me explain a little bit more in the sections below. I will go into the different variations of titanium knives so that you can leave here with a full understanding of how this all works.
Full Titanium Blades
Alright, so first off we have the full titanium knife blades. Well, technically titanium blades are never COMPLETELY made of just titanium. To make the blades more useful and durable, full titanium knife blades are technically made of titanium alloy and not pure titanium.
I’m not going to bore you out of your mind by going into the super specifics of titanium alloys, but I’ll give you a quick overview. Titanium alloys are basically titanium mixed with a bunch of other materials and elements to create a more durable and strong metal that will stand up to being used as a knife blade.
Some of the most common titanium alloys are composed of specific percentages of Iron, Oxygen, Carbon, Nitrogen, Hydrogen, and a bunch of others. Depending on the makeup of the specific alloy, it might be designed to be super durable, hold an edge well, or a host of other traits.
| Type | Aluminum | Vanadium | Iron | Oxygen | Carbon | Nitrogen | Hydrogen | Tin | Copper | Titanium |
| 6AL4V | 6.00% | 4.00% | 0.40% | 0.20% | 0.08% | 0.05% | 0.01% | 0.00% | 0.00% | Balance |
| Grade 9 | 3.00% | 2.50% | 0.25% | 0.15% | 0.08% | 0.03% | 0.01% | 0.00% | 0.00% | Balance |
| 662 | 6.00% | 6.00% | 0.50% | 0.00% | 0.00% | 0.00% | 0.00% | 2.00% | 0.50% | Balance |

There are a bunch of different titanium alloys and they all have their specific uses. The above table just shows some popular alloys and their makeup. As you can see, there is really no such thing as a full titanium knife blade, because it would be too soft without the other elements added in.
Even so, because the added elements in a titanium alloy only make up a few percent of alloy, “full” titanium knife blades are usually not very magnetic, if at all. There will obviously be a little bit of magnetism present in the blade, but it will be hardly noticeable because the majority of the alloy is made up of titanium which is not magnetic.
Coated Titanium Blades
The ever-popular titanium-coated knife blade is also something to consider when we talk about the magnetism of titanium knives. As the name implies, titanium coated blades are simply steel knife blades that have a protective/aesthetic coating of titanium on them.
This coating of titanium is usually pretty thin, which means the non-magnetic qualities of titanium are pretty minimal on coated knife blades. Titanium coated knife blades usually have the same magnetism of the original steel or alloy that was used to make the main portion of the blade.
So, depending on what the blade is made of under the titanium coating it could be magnetic or not. Usually, the steels that are used for most pocket knives and other common blades are magnetic and have those same properties even with a titanium coating on them.
Basically, it all depends on what the blade of the knife is actually made of and the titanium coating has almost no impact on the magnetism of the knife. But in general, most titanium coated knives are magnetic in my experience because the vast majority of steels used to make knives have magnetic properties.
At this point, I hope you are beginning to understand the basics of titanium knives and how the magnetism of the blade relates to the makeup of the knife. Below I am going to go into more detail into the properties of titanium and some of the uses and reasons you might want to know if your knife is magnetic or not. So if you’re still interested and have read this far, there’s more great information ahead!
Is Titanium Itself Magnetic?
In a scientific sense, titanium is technically magnetic. However, the magnetic properties of titanium are VERY small and to the average person, titanium would seem non-magnetic when placed next to a magnet.
So while technically titanium is slightly magnetic, it is a pretty safe bet to just call it non-magnetic. It is definitely not enough to make it attracted to magnets or be noticeable in any way to the naked human eye.
Virtually pure titanium is ever so SLIGHTLY magnetic, so just imagine how magnetic titanium alloy is! A lot of titanium alloys are ~90% titanium which makes them not magnetic at all (at least to the casual observer).
So yeah, I hope that clears up any confusion you might have had over the magnetic properties of titanium. In the next few sections, I’m gonna go over some of the uses and reasons why you might want to know if your knife blade is magnetic or not.
Why You Might Care if a Knife Blade is Magnetic or Not
Well, now we are getting to the good part. In the previous parts of this article, I have gone over the basics of if a titanium knife is magnetic or not, but at long last, we get to discuss WHY this information might be important.
And instead of just saying “there are many different instances and scenarios where this might become important”, I have decided to give you a list of some of the most common reasons for wanting to know if your knife is magnetic or not. So keep reading and let’s just get right into it.
Magnetic Knife Holders
One of the most popular reasons for wanting to know if a titanium knife is magnetic or not is because of magnetic knife holders. Over the last couple of years, the popularity of magnetic knife holders have just exploded along with titanium knives.
Clearly, if a knife is not magnetic it will not work at all with a magnetic knife holder so this is actually quite an important question. This often comes up with titanium kitchen knives, but it is a common question with hunting, fishing, and everyday carry knives as well.
Military Applications
The military has many special and specific jobs that have to be done, and some of those jobs require knives. More specifically, non-magnetic knives.
This could be for a variety of different reasons, but one of the most talkies about reasons is for disarming land mines. While I’m no expert on land mines, apparently a non-magnetic knife blade is needed to disarm them for whatever reason.
Some Metal Detectors
If setup and used properly, most modern metal detectors can pick up on titanium both in its pure form and titanium alloys. However, it really depends on the design and search coils of the detector whether or not it can pick up on titanium.
This isn’t often a problem or really anything that crosses people’s minds often, but it could be important at airports or really anywhere where there are metal detectors stationed. Its just good to know whether or not a pocket knife will cause an issue or not at a metal detector.
Other Reasons
There are almost infinite reasons and situations where you might want to know if a titanium knife is magnetic or not. The list could go on forever with the reasons that people come up with!
So I’m just going to end the list here because I have basically covered most of the common situations where this information might be important. Hope you found this helpful and gained some sort of information from my rambling!
There are a lot of great titanium knives out there on the market today, but here are some of my favorite titanium knives and some of the most popular ones:
