When it comes to combat knives, function and form are far more important than aesthetics. The form? Combat knives used by militaries around the world all share one thing in common: they have a fixed blade.
A fixed blade is strong and reliable. Simplicity, including lack of moving parts is a good thing when your knife might make a life-or-death difference when used.
Not in the military? Not interested in military surplus shopping? No problem. Knife manufacturers have studied military knives and created great look-a-like knives for us civilians.
Better yet, there are plenty of models that not only take a nod from a military knife, but improve upon it, too. Below we’ve compiled a mix of real-world combat knives designed by the world’s top knife brands.

What to look for when choosing a combat knife
Those are the 5 best combat knives that we could find. Each knife has unique qualities that are all capable of just about anything you will need a knife to do. Hopefully, you found something that will suit you well. That said, if you are still on the fence and not sure what knife is best for you, do not worry, we will now cover the basics of combat knives. Everything from the blade, the handle, and overall design will be examined. We hope to help educate you on what makes the best fighting knives, combat knives, and utility knives. So, Let’s get started.
The anatomy of a combat knife blade will differ from knife to knife. Some are pretty basic, like the number 5 knife on our list the Ka-Bar USMC combat knife. It has a clip point face, a straight edge, and a straight spine. Even if you think this is a boring design, it was the most popular combat knife during WWII and is still popular to this day. Sometimes simplicity is all you need in a knife.
If you are on the hunt for something a little more ambidextrous, there are plenty of knives that offer much more. Combat knives can have partially serrated edges, completely serrated edges, or different types of knife points. A knife’s point is actually one of the most important aspects of the blade. Each type of knifepoint is specifically designed to complete a specific task. Some knife points like the clip point or the drop point are good for multiple uses. Although, they are best at piercing and slicing. While other knife points are pretty specialized for one purpose. The talon point is a perfect example of this. A talon point is shaped, well, like a talon. It is designed to slice through fabrics like carpet or the belly of a fresh hunting kill.
The blade of a combat knife is ultimately the most important part of the knife. Knife blades do all of the heavy lifting when cutting, slicing, or piercing. As we learned, some knife blades are pretty universal. While others are designed for a more specific function.
While the blade will be doing most of the work, the handle is of equal importance, because without it, a knife would be useless.
A knife’s handle is in some ways it’s Achilles heel. If it functions the way it is designed, you will not notice. Only when the knife handle fails or is off balance is when a user will notice. To understand the anatomy of a handle you first need to understand the difference between a full tang knife and one that is not. A full tang knife is one solid piece, both the blade and the handle are one piece. This gives the knife increased structural ability. When great pressures are applied you will not have to worry about the blade snapping off of the handle, because the blade and the handle are one.
Typically a full tang knife will have two pieces that cover the steel handle portion of the knife. These can be made from several different types of materials. The most common materials used on contemporary knives will be synthetic. Synthetic materials like nylon or polyurethane are much more resilient than more traditional materials like leather or wood. Not only can they take more of a beating, but it also holds a better grip. The ability to mold with these materials makes it easier to add textures to them, increasing the overall control a user has over the blade. Materials like wood and leather are still popular amongst many knife enthusiasts today. They just need more care and attention than synthetic handles. Partial tang knives on the other hand only extend partially into the handle. While they are not as solid as a full tang, if they are built correctly they are just as sturdy. They use the same materials as full tang knives, only their construction is different.
Now that we have a better understanding of the blade and the handle, let’s talk about knives overall design.
The overall design of a knife is essential to its function. The best combat knives have the perfect balance between blade and handle. A knife’s handle should be ergonomic, fitting naturally in your hand. While the blade should only feel like the extension of your hand, not like a foreign object. Weight is an all-important factor in knife design as well. Both the handle and blade should be perfectly balanced. One should not outweigh the other. If a knife does happen to be off-balance, a user will be conscious of it, ultimately this imbalance will alter a user’s movements and work.
Another aspect of a knife’s design is its overall size. Smaller combat knives will be easier to carry, transport, and control in the hand. The way they are built is essentially the same, just less material. Larger knives can be a bit comedic depending on their size. A bowie knife can be up to 18 inches in length with a knife face as wide as a dinner plate. While the Bowie knife is iconic, a knife half its size can do the same things, if not better. Ultimately the knife design you favor will be up to you to decide. Usually, it is wiser to go with a size that is practical for daily use, but a lot of this will come with trial and error.
With the understanding of the blade, handle, and overall design, we can talk about the extras that oftentimes come with the best combat knives.
The word utility is defined as “the state of being useful, profitable, or beneficial.” A combat knife can provide all of these things. It is useful in combat situations. It can be profitable in terms of dressing animals and selling their meat or hide. Lastly, it can be beneficial to everyone that uses it. Combat knives or knives in general usually have added features on a knife that can be used in ways that a normal straight edge knife could not. This is due to a combat knife’s increased size, giving blade smiths more room to work with.
Some added feature includes gut hooks, partially serrated edges, and saw back spines. These additions take on capabilities that a normal knife would struggle to do. Increasing its usefulness and profitability, ultimately benefiting the user. All in all combat knives are a great utility to the user.
Now that we have covered the basics of combat knives, we need to talk about their legality. Because oftentimes people find themselves in trouble when it is easy to avoid.
The legality of a combat knife will depend on a lot of different factors. Where you live in the largest determining factor of all. If you are in the United States, it will depend on state and city ordinances. Some cities will allow civilians to carry large combat knives as long as they are in plain sight and in a sheath. Other cities or states only allow up to a certain blade length. We highly advise that you are up to date and aware of your local laws before you walk around with your Ka-Bar.
