The Best Blade Materials For Folding Tactical Knives: Exploring Durability And Sharpenability

Folding tactical knives are a pretty new concept, having been introduced only in the past few years. While some have started to popularize them as convenient ways to carry several knife types, these knives are not without their challenges.

For starters, the length of the blade must be long enough to fit into your pocket comfortably and long enough to put away safely when you are finished using it. Then, there is the question of whether or not you want a plain or concave blade, the answer to which being yes or no.

If you want a serration on your knife, then there is only one correct material: carbon fiber! If you want noncarbon fiber style knives, then there are some good solutions for you: composites like plastic or foam padding, or even solid backbones like steel and glass.

This article will go into some detail about some of these different blades materials and how they work and maintain their sharpness.

Carbon steel

Carbon steel is a very durable material. This steel can last generations using only minimal maintenance. Because it does not require special tools to sharpen, it makes it very long before its useful life is over!

Unfortunately, this can be an expensive material. Most carbon steels are coated with costly alloying agents to protect them. Without those, they are quite useless! But you can buy them as plain carbon steel blades.!)

Some people prefer the look and scent of carbon steel. If you are looking for a new blade material to switch up with, give some of these materials a try: D2 ultra-hard; N5 high-carbon; and G10 laminate surfaces are vulnerable to oils and grease, so never store your knife without a protective case or cover.

Stainless steel

Versatile and strong, stainless steel is one of the most popular materials for folding tactical knives. This type of steel can be sharpened to a beautifully smooth finish or can be treated with fine-grain powder to create a sharper edge.

Stainless steel knives have a short lifespan when it comes to keeping an edge. Because it is not practical to sharpen the blade every time you purchase the knife, it can be hard to value the knife. However, because the blade can last quite awhile without being sharpened, this saves money in replacement fees.

Some people worry about exposure to stainless steel objects such as cookware and medicine cabinets, but this cannot affect the hardness of thesteel.


Titanium is one of the most popular steel blade materials. This material does not get very hot to touch or hold, which makes it very durable.

It can also be sharpened easily, making it a favorite among folding tactical knives buyers. Because it can be sharpened so easily, some people even prefer to call it a serrated blade instead of a plain blade.

Because it does not retain its edge as well as other steel materials, some people recommend using a modest amount of knife oil to maintain the edge.


Copper is one of the most common blade materials used in folding knives. It has a long history in military and police applications, where durability is important.

Copper is one of the harder of the Metal Elements metals. This means that it can be beaten into a powdery substance when struck, making it easier to sharpen.

While too coarse for some purposes (such as an artistic folding knife), copper does hold its color well, so you can stain things easily. Plus, if you need to sharpen it more quickly, you can!

Like steel, copper knives require dry sharpening techniques such as carborundum or at-home stones.


Steel is the most common blade material. It is cheap and easy to work with. Most steel knives have a polished or rolled edge. This means the majority of the knife blade is hard plastic or metal that is folded over and glued down at one end.

This gives the knife its name: roll-up knife. The others is its rounded end, which makes it stand out from a long stick of de-inked paper.

Because steel is so common, many people do not investigate which materials are used in their knives. This can be dangerous! Many steel knives do not last as long as regular knives due to poor maintenance.

Steel blades can get dull easily and stay that way because they are not good at holding an edge.


MoS2:ledge is a relatively new blade material that has gained a lot of popularity in the folding knife community. MoS2:ledge is a synthetic material that is created by layering several different synthetic layers together.

The result is a durable, flexible blade material that can be sharpened easily. MoS2:ledge is typically sold as an ultraslim blade material, which makes it even more desirable to use as a foldable knife.

Despite its popularity, many users complain about the fact that MoS2:ledge can be hard to sharpen. This can be problematic if you do not have the proper tools at your disposal!

To help address this issue, here are some tips on how to properly use and care for your Mos2:lude.


NiBiTor+ is a new material that has gained a lot of popularity in the last year. It is a hybridized carbon nanotube material that has garnered a lot of attention due to its cost-effective and durable nature.

When looking at carbon nanotubes, they can very much look like wood or paper tubes. These tubes are solid and cannot be damaged in any way. However, the internal structure of the tube can be hollow, allowing for gas and molecules to flow inside. This makes it look like the tube is rotating or spiraling, making it very attractive and unique.

Many people use NiBiTor+ as their main folding blade material. It has excellent sharpening abilities and does not dull easily. It also does not stick too well to knives with colder steel surfaces, which makes it more versatile for survival situations or engagements where you need a knife regularly.
