Features to Consider Before Buying

We’ve listed features we believe may matter the most when it comes to combat knives. However, don’t forget to always take into consideration your personal preferences as well!

Blade Material

Blades are primarily made of three types of steel: high carbon stainless steel, stainless steel, and carbon. You should know that not all blades can be combat knives. You have to understand the types of steel material used to be able to select the best fighting blade.

Carbon is moderately soft and it is easy to sharpen. Carbon does not hold an edge as you will expect, and you must continuously sharpen it in order for it to be useful. Carbon has one major disadvantage, which is rusting. It does not matter whether you clean the knife after using or not, it will still rust.

Stainless steel is the most solid of the three steel materials; however, stainless is difficult to sharpen. The good thing about stainless steel is that it keeps an edge for a long time once sharpened. A feature unique to stainless steel is its high resistance to rust, it simply does not rust.


High carbon stainless steel is the most preferred of the three materials. High carbon stainless has the properties of both carbon and stainless. It provides you with the best cutting features. It is easy to sharpen and it holds the blade longer than carbon steel.

Knife Grounding

Combat knife edges are usually grounded into one of the following shapes: taper ground, hollow ground, and flat ground. A taper grounded blade has less dragging and more strength. As far as taper grounding is concerned, an additional grind is made after the flat grind so as to thin out the blade. This is the best grind for a combat blade.

However, you can still consider hollow ground or flat ground. The edges of flat ground blades are evenly grounded from the back of the blade to the front and from the heel to the point. On the other hand, hollow ground edges have thinned portion of the knife blade situated behind the edge.

Handle Design & Material

A good combat knife must have an ergonomic handle. The design of the handle is important to the function of the knife. The energy you need for stabbing or cutting must come through the handle. Therefore, the handle design is an important factor when selecting a combat blade.


The design usually ranges from simple plastic handles to beautifully curved handles. A reliable combat knife should have a well-designed as well as the comfortable hand-sized handle. The handle should also have a large hilt, providing a high stabbing force.

This makes it easier to transfer the maximum amount of energy from hand and into the blade. This simply means that the coupling between your hand and your knife’s handle must be reliable. The handle material is extremely important when buying fighting knives. It should be designed from a material that is resistant to warping and shrinking and does not absorb moisture.

The best handles are engineered from plastic-wood laminates or close-grained hardwood. In some cases, high-quality plastic is reliable but may be slippery when wet. You can also consider knives with aluminum, steel, hard rubber, bone ivory, rosewood or walnut handles.

It is important to examine the manner in which the knife you are about to buy is assembled. Check how the handle is fixed to the stiletto. The best knives have tangs that are forged from the same material as the blade. This ensures that the knife is stronger.

fixed and folding knife

Make sure the tang is well securely inside the handle, with at least two rivets. The new field of synthetic knife handles includes rubberized material. Always choose a handle that is not only comfortable to hold but has the energy required for combat.

Plain or Serrated Edge

A plain edge is a single edge blade that has no teeth or serrations on the cutting surface. On the other hand, a serrated edge has teeth or serrations cut into the blade. In most knives, the serrated part of the blade can be a small section towards the back of the blade or it can cover three-quarters of the blade.

Serrated edges are very resourceful for cutting through tough material. Serrated knives are usually larger and for some, longer. You can also choose a knife with double serration.


This is an essential accessory for a combat knife. This is so because it affects how you store your knife and how you carry and draw it when in a fight, hunting or survival situation. You need to consider the lower attachment of the sheath before buying a knife.

Choose a sheath that has a belt and lanyard attachment, and make sure the sheath has a hole for a lanyard. You also have to consider how the sheath will close around the knife. Choose one that has a crossover strap at the point where the handle meets the sheath.

Bearing all of those features in mind, let’s move on to the list of actual products.

  • The main criterion for selection of a knife is its purpose. The variety of models and types of knives is precisely determined by a variety of tasks. The knife must not only be well adapted to solve a particular task or of their circle, but for the specific climate zone. So, a knife with a metal handle is unlikely to be suitable for the far North, and a knife with stacked leather handle won’t please his master in the humid jungle. Hence, the criteria for the type of material used as the handle, the blade, and scabbard.

    • The purpose part is one of the most overlooked features of a knife, which is quite ironic if you’ll ask me. We know knives have a sole purpose of cutting things, but they vary in what they can cut. Other than this, make sure the knife you’re buying is durable enough for the job as well.

  • Camping knife is among the accessories for fishing, hunting, and travel, which, as they say, are not discussed. That is, it must be without exceptions. During the short expeditions (a day or less) I’m always folding a swiss knife type “Victorinox” with a maximum length of the blade, but on longer trips, I always add the “normal” knife in the scabbard, like one of those that makes the German manufacturer Eickhorn. In this article, this brand is represented with a “FAIRBAIRN SYKES 2000 FS2000 DAGGER KNIFE”.

    • Great points raised, Dominick. We really cannot settle for just “one” knife because of the varying uses and requirements involved wherever we go. The safest number of knives to keep in my opinion is at least three, with one being a folding knife and a standard knife. The third one is an optional full-sized knife for multi-purpose use.
