Choosing The Best Survival Knife: A Comprehensive Guide

You never know what challenges you might face while in the wilderness. A reliable survival knife can help you overcome those challenges by providing a range of functions, including cutting rope, slicing through rigid materials like leather or canvas, digging holes or trenches for shelter-building purposes, and skinning game animals for food preparation, among many others.

In an emergency where every second counts, having a high-quality survival knife can make all the difference in your safety and well-being. A good-quality blade is imperative, as it will hold its edge longer than substandard ones. At the same time, its construction should be sturdy enough to handle any demanding job thrown at it without compromising its strength.

A well-made knife is also an investment that will last years, if not decades, with proper care. Investing in a reliable survival knife is an intelligent decision for adventurers and essential for anyone who values their safety and well-being in the great outdoors.

Blade Types and Materials

Straight, Serrated, or Partially Serrated Blades?

There are three joint blade edges for survival knives: straight, serrated, and partially serrated. Straight blades are great for slicing through materials like rope or fabric. They also require less maintenance as they don’t dull as quickly as serrated blades. However, they can be less effective when sawing or cutting through more rigid materials.

Serrated blades have a jagged edge perfect for sawing through thick branches or fibrous materials like bone and tendons. They are also better at maintaining their sharpness over time than straight blades. However, they can be more challenging to sharpen and may not be ideal for tasks that require precision cutting. Partially serrated blades offer the best of both worlds.

The front portion of the blade is straight, while the back part is serrated. This design allows you to use the straight portion for slicing and the serrated portion for sawing without switching knives.

Carbon Steel vs. Stainless Steel Blades

Blade material is another critical factor when choosing a survival knife. Carbon steel and stainless steel are two of the most popular types of steel used in knife making.

Carbon steel blades are known for their hardness and durability. They hold an edge well but require more maintenance than stainless steel because they rust quickly if not cared for properly.

Carbon steel is more easily sharpened than stainless steel but may develop nicks if used heavily over time. Stainless steel blades don’t rust as easily as carbon steel because they contain chromium, preventing oxidation.

They also require less maintenance than carbon steel but may not hold an edge. Stainless steel tends to be more flexible than carbon steel, making it ideal for tasks requiring flexibility, such as filleting fish.

Blade Shapes and Grinds

Common Blade Shapes

There are several standard blade shapes for survival knives to consider. The drop-point blade is perhaps the most versatile, ideal for performing various tasks such as skinning game, slicing through rope or foliage, or carving wood. The edge is characterized by a convex curve from the knife’s spine to its tip.

The clip-point blade features a concave curve on the back of the blade that creates a sharper tip for piercing and detailed cuts. This shape is popular among hunters and outdoors people who need a knife for skinning games or performing delicate work.

The tanto blade shape was initially designed for Japanese samurai swords but has since been adapted for modern knives. The tanto features two straight edges that meet at an angle, creating a solid tip for piercing hard materials like bone or wood.

Popular Grinds

The grind of a knife refers to how the blade tapers from its spine to its edge. Two common grinds are full flat grind and hollow grind.

A full flat grind means that both sides of the blade taper evenly from spine to edge, resulting in a sharp but relatively thin cutting edge. This type of grind is ideal for tasks requiring precision slicing, like preparing food or carving wood.

On the other hand, hollow grinds are characterized by concave curves on both sides of the blade, creating an extremely sharp but somewhat fragile edge. Open tasks are popular among hunting knives because they allow you to make clean cuts without damaging meat or hide.

Advantages and Disadvantages

Each shape and grind has advantages and disadvantages, depending on how you plan to use your survival knife. For instance, while tanto blades offer excellent piercing capabilities due to their vital tip, their straight edges can make them somewhat less versatile than drop-point blades.

Similarly, while full flat grinds produce an extremely sharp edge ideal for precision slicing, the thin blade may not be strong enough to handle more heavy-duty tasks. And while hollow efforts are perfect for making clean cuts on game or fish, they can be difficult to sharpen and maintain over time.

Ultimately, your survival knife’s best blade shape and grind will depend on your needs and preferences. Consider factors like what kind of tasks you’ll primarily use your knife for and how often you’ll need to sharpen it when choosing a blade shape and grind.

Handle Materials and Designs

Common Handle Materials

The handle of a survival knife is just as crucial as its blade. Common materials used for the handle include wood, synthetic materials, and rubber.

Each material has its advantages and disadvantages. Wooden handles offer a classic look and feel but may not be as durable as synthetic materials or rubber.

Synthetic materials such as G10 or Micarta are lightweight and resistant to moisture and temperature changes. Some knives also have a rubberized grip for added comfort and traction.

Ergonomic Handle Designs for Comfortable Grip

Survival knives are often used in challenging environments where grip can make all the difference. The handle design should allow for a comfortable grip even when wet or with gloves on. Ergonomic handles often feature finger grooves or contours that fit the natural shape of the hand, reducing fatigue during extended use.

Additional Features Such as Finger Grooves or Lanyard Holes

Some survival knives have additional features that make them even more versatile. Finger grooves provide added control during precision tasks such as carving, while lanyard holes allow the blade to be attached to a belt or backpack for easy access while on the go. When choosing a survival knife, consider what handle material best suits your needs based on your intended use.

Ergonomic designs are highly recommended if you use your knife extensively over time, especially if you have larger hands or plan to wear gloves. Additional features such as finger grooves or lanyard holes can add value depending on your specific needs in the field.

Tang Types

Full Tang vs. Partial Tang: The Basics

A knife’s tang is the blade’s portion that extends into the handle. Essentially, it’s what holds the edge and handles it together. There are two main tang types to consider when shopping for a survival knife: full tang and partial tang.

Full-tang knives have a blade that extends through the handle, providing strength and stability throughout the knife. In contrast, partial-tang knives have a shorter edge that only extends partway into the handle.

The Benefits of Full Tang Knives

There are several advantages to choosing a full-tang survival knife over a partial tang model. One significant benefit is increased durability. Because the blade runs through the entire length of the handle, there are no weak points or vulnerable areas where it could break or become damaged.

Full-tang knives also offer better balance and control when in use. This is especially important for outdoor activities like camping or hiking, where extra precision is needed.

The Drawbacks of Full Tang Knives

While there are many benefits to choosing a full-tang survival knife, there are also some potential drawbacks. One main downside is that they can be more expensive than partial-tang models due to their higher-quality construction.

Another possible drawback is weight—because full-tang knives use more materials in their construction (to accommodate their longer length), they can sometimes be heavier than other types of blades on the market. This may be an issue for those who prefer lightweight gear.

Full-tang and partial-tang models can make excellent choices depending on your specific needs and preferences. By carefully evaluating your needs before making your purchase decision, you’ll increase your chances of finding a survival knife that will serve you well for many years.

Sheath Options

Different types of sheaths are available.

When it comes to choosing a sheath for your survival knife, there are several options available. The most common types include leather, nylon, and Kydex.

Leather is a classic option that looks great and feels good in the hand. However, it’s not as durable as the other options and may require more maintenance.

Nylon is water-resistant and durable but lacks the aesthetic appeal of leather. Kydex is a thermoplastic material that’s highly durable and easy to clean but may not be very comfortable to wear.

Aside from the material used for the sheath, you’ll also want to consider additional features such as belt loops or clips for easy attachment to your gear. Some sheaths have extra pockets or holders for sharpening stones or fire starters.

Factors to consider when choosing a sheath

When choosing a sheath for your survival knife, consider factors such as durability, comfort, accessibility, and versatility. A good sheath should protect your blade from damage while being comfortable to wear throughout the day.

Durability is paramount if you plan to take your knife into harsh environments where it may be exposed to water or extreme temperatures. In these situations, a kydex or nylon sheath may be better suited than leather.

Accessibility is another critical factor to consider when choosing a sheath. You’ll want something that allows quick access to your knife in emergencies but still holds it securely in place when not in use.

Versatility is essential if you use your survival knife for multiple purposes, such as hunting or fishing. Look for a sheath that can accommodate additional tools, such as fishing hooks or saw blades,

Selecting the correct type of sheath depends on your preference and the conditions you plan to use your survival knife. Consider materials, additional features, and durability when ensuring a sheath that will protect and serve your knife well for years.

Maintenance Tips

Keep Your Blade Clean

Keeping your survival knife clean is essential to maintaining its longevity and ensuring optimal performance. After each use, wipe down the blade with a clean, dry cloth to remove dirt or debris.

You can also clean the blade thoroughly with soap and water. However, to prevent rusting, dry it off entirely afterward.

Oil the Blade Regularly

Another crucial maintenance tip is to oil your survival knife regularly. This helps prevent rust and corrosion from developing on the blade.

To do this, apply a small amount of oil to a clean cloth and rub it gently onto the blade’s surface. Any oil will work for this purpose, but vegetable or mineral oil is a good option.

Sharpen Your Knife Regularly

Sharpening your survival knife regularly ensures it remains sharp and always ready for use. There are several ways to sharpen a knife, including using a sharpening stone or honing rod. However, choose the best method for your specific blade material and shape.

Proper Cleaning Techniques

Avoid Harsh Chemicals

Avoid using harsh chemicals or abrasive materials that can damage the blade’s surface when cleaning your survival knife with soap and water or other cleaning solutions. Instead, opt for mild dish soap or even just water, if possible.

Dry Thoroughly After Cleaning

After cleaning your survival knife, dry it thoroughly before storing it in its sheath or other storage container. This will help prevent rust from forming on the blade’s surface over time.

Sharpening Methods for Different Types of Blades

Straight Blade Knives

A sharpening stone is the best method for straight-blade knives to achieve optimal sharpness. To use a sharpening stone, place the blade’s edge against the rock and move it back and forth in a circular motion until it becomes sharp. Be sure to maintain a consistent angle while sharpening to ensure even results.

Serrated Blade Knives

Serrated blades require a different approach to sharpening than straight blades. The best method for sharpening serrated knives is to use a tapered round file or diamond rod. Run the file or rod along each serration until it becomes sharp.

Hollow Grind Blades

Hollow grind blades have concave edges that are ideal for cutting through rigid materials quickly and efficiently. To sharpen this blade type, use a small honing rod or diamond file to hone the edge’s inside curve.

Following these maintenance tips and using proper cleaning and sharpening techniques ensures that your survival knife remains in excellent condition for years. Remember that taking care of your knife is critical if you want it to perform well when needed—out in the wilderness!

Survival Uses for a Knife

Building Shelter or Fire

A good survival knife can help you build a shelter or fire in the wilderness. A sturdy blade will make cutting branches and other necessary materials easier to construct your shelter. You can also use your knife to prepare kindling to start a fire.

If you need to start a fire, your knife can create sparks by striking it against a rock or other hard surface. Alternatively, if you have the correct type of steel on your blade, you may be able to create sparks by striking it against another piece of metal.

Preparing Food or Hunting Game

Another important use of a survival knife is preparing food. Whether hunting game or organizing wild berries, having a good blade will make the process much easier. You may also need to skin and gut an animal before cooking it over an open flame, and a sharp blade will simplify these tasks.

If you’re planning on hunting a game with your survival knife, there are some essential things to keep in mind. First, make sure that your local laws allow hunting with knives; in many places, this is illegal.

Secondly, practice using your knife ahead of time so that you’re comfortable with its weight and feel. Always respect the animals you hunt and only take what you need.

First Aid Applications

In addition to building shelter and preparing food, a good survival knife can also be helpful for first aid applications. If someone is injured in the wilderness, having access to clean water and medical supplies is essential, but if those things aren’t available, your knife can help.

You might use your knife blade as an improvised scalpel if someone needs stitches or has an abscess that needs to be drained. You can also use your knife to remove clothing or other materials obstructing an injury or wound.

Clean your blade thoroughly before and after using it for first aid to avoid introducing unwanted bacteria into the wound. A survival knife is an incredibly versatile tool that can help you in various ways if you’re stranded in the wilderness.

Building shelter, preparing food, hunting games, or providing first aid, having a reliable blade on hand will make things much more manageable. So invest in a good-quality survival knife and learn how to use it effectively—you never know when it might just save your life!
