The knife features a 12-inch length with a 7-inch black stainless steel blade. The design features a serrated top for a perfect saw body.
The double-edge design of the knife provides for a good design that lets you make secure cuts from either direction. You can keep the two halves sharp at the same time for a more consistent cut while being flexible.

2. United Cutlery USMC Combat Fighter Pocket Knife – A Smaller Choice
United Cutlery makes this smaller pocket knife with a body inspired by the Marines. The layout is influenced by the traditional Marine fixed blade knife. Everything on the knife produces a brilliant look that will stand out in a crowd. But the general functionality of the knife is also essential to note.
The TPU handle features a 3D-printed body that looks like the leather handle that the Marines use in their knives. The design comes with a few grooves for your fingers to produce a better hold.
The pocket knife has a retractable body that lets you move the blade into the handle compartment when not in use. The locking mechanism ensures that the blade doesn’t come out unless you use the proper trigger movement. It is also easy to move the blade back into the compartment without potentially harming yourself. The positioning on the end is easy to follow and control.
The stainless steel blade is about 4 inches in length. The handle is slightly longer, which is a necessity for keeping the blade functional. The non-reflective finish on the body provides a distinct look that isn’t overly distracting.
3. Ontario Knife Company 8679 Sp-1 Combat Knife – Compact and Firm
The carbon steel body on this next combat knife from the Ontario Knife Company is worth exploring. The firm layout on this clip point knife provides a body that lasts for years and will not wear out or weaken over time.

The layout prevents the knife from slipping off and possibly hurting someone. More importantly, the arrangement works in either hand for comfort and functionality.
The shoelace feature at the bottom part will help you affix the knife to your hand while in use. The shoelace attachment won’t take up lots of room, nor is it going to add lots of weight.
4. CRKY Shrill Fixed Blade Knife – Features a Powerful Spear Point
The spear point blade on this CRKY combat knife features a titanium body that resists rust and adds a brilliant silver look. The spear point is also fully sharpened to create a better cut on either side.
The dual-edge design provides an even cut on each half. The knife itself is also relatively thin, at about 0.15 inches in thickness. The slim body keeps the weight on the blade minimal, but it also adds a powerful look all around. The knife is a little over four ounces in weight. The sheath doesn’t add much outside of that.
The handle features a resin body. The infused fibers provide a better hold that won’t wear. You’ll also notice a slight curve in the middle part to produce an even look that works in moments.
A leather sheath appears with this knife. The sheath features a boot clip for convenient storage and concealment.
The full tang feature on the knife provides a one-piece body. The design requires little maintenance outside of the traditional cleaning and sharpening efforts you’d have to complete.
5. Gerber Hinderer Combat Life Saver Knife – Helpful For Many Purposes
The general functionality of a tactical combat knife can be critical for its use. You’ll need a knife that can handle multiple things, particularly for life-saving needs. This Gerber knife features a sturdy stainless steel body and a helpful serrated end, but there are a few additional features on the handle to note.
The handle comes with a seat belt cutter. The component appears on the side of the handle. You can open the spot to allow the cutter to stay open.
The back end has a pointed spot that works as a window punch tool. While many knives already have handles that work well for breaking glass, the window punch on this one has a small and concentrated body. The arrangement lets you puncture a window for fast access when you need it the most.
The handle comes with a small curve at the front to help you in carrying and wielding the knife. A liner lock release feature also appears in the curved area. The layout lets you get the knife ready for use in moments. The array works well for emergency purposes.
6. Smith and Wesson SWHRT9B 9in High Carbon Fixed Blade Knife – Comes With a Great Handle
Smith and Wesson have been one of the top companies in the world of firearms for generations. The company also makes combat knives like this model. This nine-inch fixed blade knife has a carbon steel body, but the handle is what makes this one so useful.
The handle features a rubber-wrapped body that sticks to your hand quite well. The wrapping features a few grooves in the middle. The grooves match up with the user’s fingers in most situations. You’ll also notice a slight series of curves on the top and bottom parts of the handle. The design adds a good touch.

The design also works with many angles and cutting patterns in mind. The stainless steel body is easy to sharpen and provides a better cut all around.
You’ll note a lanyard hole at the back end. The hole is suitable for most string types, especially when you’re aiming to get a better hold of your knife.
The slight bend at the end of the handle also adds a good grip. The bend helps for breaking glass or other sturdy items. You’ll also see a few grooves on the top part of the handle to help you keep a better hold all the way through.
The point you’ll notice on the end of the blade features a great edge that provides a better hold for cutting. The point ensures you can puncture through more items quite well.
8. Glock Perfection OEM Fixed Straight Blade Field Knife – A Useful Saw-Like Body
You will appreciate how well this Glock knife works. The Perfection knife comes from the same company that is also known for making firearms. The Glock knife comes with a clip point blade, but the serrated end on one half makes for something useful.
The serrated end on the bottom part provides enough room to where the knife could also work as a saw of sorts. The design provides enough help with cutting through materials, especially if you’re trying to work with rope or wood materials. The coating on the steel blade also ensures that the blade will not be harmed by corrosive materials.
The other end features a traditional knife blade. The plain edge helps when you’re trying to open items or slice open some thicker materials. But the saw is best for when you have something a little more stubborn, and you need extra traction and support.
The firm handle is strong enough to puncture through the glass, but still smooth enough to give you a comfortable hold. The body features a better grip that works fast and adds a nice touch all around.
9. Ka-Bar Full-Size US Marine Corps Fighting Knife – Inspired By Tradition
This next tactical knife from Ka-Bar features a design heavily inspired by the US Marine Corps.

The added openings around the handle provide enough support for your fingers.
The straight edge design produces a distinct point for direct cutting purposes. The body works faster and gives you the best possible cut you could experience.
The seven-inch length on the straight blade gives you enough room for making a thorough and complete cut. The handle is a little under five inches long, thus giving you more control. The lightweight body also gives you a better hold.
A leather sheath also comes with a knife. The design comes with a belt buckle extension on the top part to help you carry the knife around well. Everything you get with this knife is all about giving you a protected and useful body that lasts for years.
10. Benchmade Nimravus 140 Knife – Provides Enough Balance

The stainless steel blade stays firm and will not rust. The design also holds its edge well, so you don’t have to sharpen it as often as you might assume you would.
The aluminum handle is about half an inch thick. You shouldn’t have much trouble getting a firm grip. The design also works on either hand. The grooves in the middle produce enough room for holding the knife without it being at risk of slipping out.
A nylon sheath adds extra protection. A clip works on the sheath for added security. The sheath is about the same weight as the knife itself, as it is thick enough to create enough protection all around.
The drop point body produces a tip that goes well through most items. The small serrated part near the tang adds an extra touch for cutting purposes.
11. Rothco Raider II Boot Knife – For Compact Needs
Your last choice to note is this boot knife from Rothco. The Raider II knife features a 6.5-inch body with about half that length going toward the drop point blade. The small and slim layout is useful for fitting around a boot. The included sheath also has a boot clip to help you affix it to your footwear without it slipping off.
The stainless steel blade lasts for years and will not develop rust or wear. The body is also sturdy enough to keep from chipping.
Another feature to note is its handle. The smooth body provides a good hold, although the best part is that it has a good handle that features a light bend. The bend has enough room for a good hold that keeps the blade intact.
The knife is also one of the lightest you’ll find. The knife weighs close to five ounces when outside its sheath. You can carry it along on a bootstrap without it bothering you.
How to Choose the Best Combat Knife?
Below are some of the important factors to be considered before buying a combat knife.
The handle on your knife entails more than how you’re going to grip the knife. The handle should also be easy to grip.
The handle can come with a slight curve. The design should be easy to grip without losing control.
Some bolts may also appear on a handle. The bolts help in securing the body of the knife. You should look for something that fits well in your hand without being distracting or otherwise tough to grip.
Length and Weight
The length and weight of the knife cannot be understated. A shorter one will require extra pressure, but it would be easier to swing and move around. A longer model will not be as easy to turn, but it can be more powerful.
The weight is also critical to note surrounding how well you can grip and use the knife. The knife should not be too heavy to where you can’t handle it well enough. There should also be enough of a balance around all parts to where one side doesn’t feel heavier than the other.
The tang is the spot on the knife that connects the blade with the handle. In many cases, the tang will be a one-piece or full layout that does not require any added bolts or fasteners.
For a partial tang, there would be a few bolts to keep the two parts together. The partial tang layout works on retractable models. You’ll need to ensure the bolts and other fasteners are secure and aren’t coming loose.
General Uses For a Knife Beyond Combat
You can use a combat knife for many intentions. While the tool is generally made with self-defense in mind, there are many other things you can use the knife for:
- Cutting branches, rope, and other thick items
- Breaking glass, particularly in a vehicle
- Trimming fabric, particularly for first-aid use
- Skinning or cutting animals and other things you might hunt
- Fighting off any live animals that might threaten you
- Prepare tinder for a fire
The functionality of the knife is strong, but the layout can also dictate what works. The physical design may feature a body that is more capable of handling certain tasks than others. Take a look at what your knife of interest can do when finding something suitable.
Straight or Folding?
Your combat knife will come in one of two forms. First, it may be a straight knife. This is a knife that comes in one piece and sticks out from the handle. You’d use a protective sheath to guard the blade when not in use.
Second, it could be a folding knife. The design is retractable and lets you secure the blade in its compartment when you’re not using it. The compartment would be inside the handle body.
You should look for a knife that is easy to use and handle for your use. The design should be flexible and useful.
Types of Knife Blades to be Consider For Combat Knife
There are multiple combat knives you can consider when finding something for your use. Part of what you should do is look at the blade type you’re getting. You have to find a blade type that fits the needs you have when using your knife. There are many common blade types to note:
1. Drop Point
The drop point blade features a cutting edge that curves up to a point at the end. The design is useful for almost anything you need.
2. Spear Point
A spear point features a symmetrical pattern. A convex curve appears near the tip. The curve produces an asymmetrical look that makes it easier for you to cut through items. The spear point should be sharp on both sides.
3. Clip Point
The forward part of the clip point blade features a slight curve. The tip moves upward to create a slanted edge. Some of these blades feature two sharp parts, one that is straight and a second that is curved. The tip works well when slicing through items.
A leaf-style blade has a concave curve with a convex curve afterward. The design produces an asymmetrical shape. The design works for hacking purposes.
5. Needle Point
The needlepoint blade is thin and features a long point. The model works mainly for piercing items. You’d be more likely to use this when trying to stab an animal that might be charging at you.
A hawkbill blade has a hooked body where the point goes down from the top of the body. The deeper curve is ideal for cutting rope.
7. Trailing Point
The trailing point blade is the opposite of the hawkbill. There is a curve on the body, but it goes upward. The blade works for slashing and skinning.
The straight back blade is also called a straight-edge blade. The design has a straight spine with a curve on the bottom. The bottom part will gradually curve up to the spine. The array creates a firm point.
General Features To Note In Your Knife’s Blade
Regardless of the specific blade you choose, you may find various things in your design. These include the following points:
The curve on the blade is a bend that will increase the general cutting potential on the knife. A curve may be convex or concave.
A convex curve places the force on one part of the blade. The blade can go a little deeper into something and produce more pressure.
A concave curve allows the force to spread out to many parts of the blade. But the item that goes inside the curve may be trapped. You’ll have to plan your cuts and other motions accordingly.
The recurve appears when a blade curves in one way and then curves in the opposite direction. The design combines the convex and concave curves together for a distinct cut.
Serrations are small jagged cuts orbits that you might find on the sharp edge of your knife. These serrations allow the knife to work as a saw when cutting things. It may be easier to get through some of the toughest fabrics or items you need to cut when there are enough serrations.
A shine might appear on your blade. The shine might make a knife look flashy, but it could do more to make it hard for people to see things when there’s a glare. You should look for something that doesn’t produce as much of a shine. It would be easier for you to see what you’re doing when there isn’t much of a shine.
What Metals Are Used In the Blades of Knife?
Your blade may feature one of many metals. The metal material should help keep the blade intact and sharp. Some of the more common metals you’ll find in your model include:
1. Stainless Steel
Stainless steel is an alloy with carbon, iron, and chromium. The added chromium produces a reflective finish, although a slight coating may go on top to prevent a distracting shine. Stainless steel will not corrode or stain.
2. Carbon Steel
Carbon steel also features carbon and iron. But the carbon content is much greater in this form. The added carbon produces a lower melting point for construction purposes. As a result, the material is more durable than something lighter. Carbon steel also distributes its energy well. You may also notice a matte finish on the carbon body, as it will not create much of a shine.
What makes titanium unique for knives is that it is very strong but also lightweight. Titanium is a low-density metal with a better strength-to-weight ratio than most other metals.
Keys For Knife Maintenance
By using these points, your combat knife can last for years to come:
Be aware of how well the knife has to be sharpened. You might need to sharpen multiple parts of the knife, depending on its blade type. Also, knives with serrated features are often harder to sharpen.
The good news is that the process for sharpening a combat knife is easy to follow. You would need a sharpening tool such as a whetstone, honing stick, or a stationary sharpener. You’ll have to sharpen the blade on occasion to ensure it stays functional.
You must look at how well you’re going to clean off your combat knife. There are a few things to note:
- Apply masking tape on the edge before you start.
- Use a compressed air blower to clear out any bits of dirt or other debris off of the knife.
- Wash the handle and blade with warm soapy water. Do not immerse the knife in the water. Use a sponge to clean it off instead.
- Use a toothbrush to clear off any grime or other things that aren’t coming off well.
- Apply more compressed air to dry off the knife.
- Remove the tape from the edge after the knife dries off.
- Use a cotton swab with rubbing alcohol to clean off the blade. Do not touch the blade yourself.
- Apply compressed air to the blade once again to dry it off.
You can also use baking soda or white vinegar to clean off any rust spots. You’d have to let the blade soak overnight while keeping the handle out of the solution. You’ll then need to clean off the knife as listed above after the rust wears off. By doing so, the knife will feel like new once again with the rusty bits coming off the body.
You must store your knife well enough to ensure its blade will stay strong and will not chip. The best idea is to store the knife in a dry and dark spot to ensure the blade won’t be influenced by anything unusual.
The great news is that many combat knives are sold with protective covers. It will be fine to keep your knife in its sheath when not in use while out in the field. But after you get back home, you should remove the knife from the sheath and place it in a dry spot. Keeping the knife in the sheath for too long can cause moisture to build up. The knife could develop rust.
A sheath cover may also feature a clip. You can apply the clip on a belt or boot, depending on the layout. You’ll need to keep the knife pointed to where you can easily access it, not to mention so it will not accidentally slip out of the storage spot.
A small lanyard hole may appear on the end of a knife. The lanyard hole lets you fit a string or other item in the body to let you carry the knife around wherever you might go. The feature is useful for when you need quick access, but you should also watch for what you’re going to use here.
Which is the best combat knife in the world?
The best combat knife in the world is the Defender Xtreme 12” Tactical Bowie Survival Hunting Knife. The knife is long enough to produce enough room for cutting, while the handle gives you enough room to secure a firm grip. The knife is also light to create enough control over the cutting experience without adding lots of weight all around.
A combat knife can be an indispensable tool for your use, but it helps to see that you know what you’re finding. Combat knives are available in many forms, and you’ll find different choices that fit your needs. You have to find something that is easy to use and works with the specific intentions you hold. Finding an ideal item for use always makes for a great experience.
