When To Use The Serrated Edge On A Survival Knife?

Carrying your survival knife when going on an adventure or packing your emergency kit is advisable. While some prefer a plain-edged survival knife, others prefer a serrated knife. The key factors that differentiate between both knives are the design and model.

Key Takeaways:

1. Types of Knife Edges:
  - Plain Edge: Best for precise cuts, push cuts (e.g., peeling fruit), and tasks requiring high accuracy and control.
  - Serrated Edge: Ideal for slicing through tough or fibrous materials like rope, synthetic fibers, and wood.
2. Survival Knife Functions:
  - Food: Effective for hunting tool creation and gathering food.
  - Shelter: Cuts saplings, strips bark, and extracts fibers for shelter building.
  - Fire: Assists in wood gathering and crafting fire-building tools.
  - Medical Needs: Useful for cutting bandages and making incisions.
  - Navigation & Transport: Can assist in watercraft construction and feature compasses for navigation.
3. Advantages of Serrated Knives:
  - Less frequent sharpening due to long-lasting sharpness.
  - Greater efficiency for sawing and downward cuts.
  - Better at gripping surfaces during cuts.
4. Knife Maintenance:
  - Recommended sharpening tools include oil, water, diamond, and ceramic stones.
  - Serrated edges are harder to sharpen but provide durable functionality.
5. Applications of Serrated Knives:
  - Combat Knives: Effective for cutting tough materials and self-defense.
  - Rescue Knives: Essential for cutting seat belts and ropes during emergencies.
  - Tactical Knives: They may feature full or partial serrated edges, depending on the task.
  - Culinary Use: Serrated knives excel at cutting bread and soft interior foods, while carving knives are better suited for clean-cut meat.

As the name suggests, a plain-edge knife has one side of its edge plain, whereas a serrated-edge knife has one of its edges jagged. This end is not smooth; rather, it’s rugged and irregular.

A serrated knife is usually employed to cut through harder materials.

Purposes Of A Serrated Edge On A Survival Knife

As different knives serve different purposes, both knives are helpful in various kinds of cuts. The way we cut an object is of two types broadly:

Push cut- In this cutting method, the knife’s edge is pushed through the object to be cut. A few examples of push cuts in our day-to-day activities are peeling an apple, shaving, chopping wood, trimming nails, etc. Plain-edge knives are usually employed for push cuts. They give clean cuts, high accuracy, and extreme control, regardless of push or sliced cuts.
Slice cut- The cutting is usually done by dragging the knives’ edges across the object to be cut. Slicing tomatoes or meat is a few examples. Sawing and slicing come under these cuts. Serrated knives are used to cut tough surfaces and for sliced cuts.

Serrated knives are used to grip the surfaces of the objects being cut. This provides rigidity and control as the serrated edges meet the objects initially, and the pressure per area increases at these points. As serrated knives have chisel ground, they possess greater slicing abilities and thinner edges.

Knowing that both plain-edge knife and serrated knife have their advantages, one tends to ponder which knife is potentially the better survival knife. A survival knife can save your life if used properly, but it could be hazardous otherwise. The knife has to be kept clean and sharp at all times as it can cause infections, otherwise, when used.

It is also important to note that the knife should not be moved erratically. The default blade length must be around four to six inches. A shorter blade gives you more flexibility to do small tasks, whereas a longer blade gives durability and power.

A good survival knife must possess the following qualities:

Fixed blade
Blade thickness of about 0.125-0.25 inches.
Full Tang
Useful sheath
Lanyard hole
Jimping
Decorative Milling
Survival but not tactical

A serrated knife is very helpful in tearing through any thick rope, dressing animals, cutting through hard surfaces, etc. They also cut through synthetic fibers and nylon webbings easily. A serrated knife is quite intimidating and is preferred by many as a primary defense. Hence, many people consider the serrated knife fit for a survival knife.

Serrations can also be of various types, such as shallow and wide, like Ontario Tak-1, or narrow and pointy, like Booker plus Steel Mariner. Each is used for different purposes, yet their essence remains the same. A serrated knife can be used in the following ways for survival:

FOOD

In the wilderness, a simple pocket knife might seem sufficient for basic food-gathering tasks, but a serrated knife can be handy or can be used to create more hunting tools by cutting and sharpening it.

SHELTER

Without proper shelter, a person can die faster out in the wild. A rugged knife can cut saplings and limbs and strip barks. In the absence of ropes or strings, one can cut through the fibers of plants to extract cordage useful for the construction of a shelter. This is usually employed by a serrated edge knife.

FIRE

With its rugged properties, a serrated edge knife can be handy for gathering wood and making a fire. It can also be used to construct fire-building tools.

MEDICAL EMERGENCIES

A knife is used to make a small incision, cut through bandages, and make slings.

NAVIGATION AND TRANSPORT

For navigation purposes, a few knives are specially built with mini compasses . While crossing through a water body, a knife is especially used in building watercraft.

The benefits of a serrated knife are:

These knives require less maintenance than plain-edge knives.
The serrated edges stay sharp for a longer time, so the sharpening of the knife need not be very frequent.
These knives work best for downward cuts.

A serrated knife must always be sharpened to get the most out of it. Various tools are available for sharpening purposes-

Oil stones can be natural stones or abrasives like silicon carbide or aluminum oxides. Coarse stones can be helpful in quicker removal of material
Water stones- They use water as a lubricant in the place of oil. They cut faster and are less expensive than oil stones.
Diamond stones- They contain microscopic-level diamond crystals tightly bonded to the surface of steel plates.
Ceramic stones- They can produce extremely sharp edges and are more expensive than oil stones. Their durability is quite high compared to oil stones.

A serrated knife is also known as a saw-toothed knife. With its cutting-edge properties, it has a smaller surface area than a smooth knife. They are generally employed when the materials to be cut are tough and fibrous.

Most self-defense professionals prefer serrated-edged knives as they easily cut flesh compared to other knives. Cuts made by a serrated knife are more precise than the ones made by a smooth blade. Though it’s a matter of preference, plain-edge, and serrated knives come in handy at different times.

Why do combat knives have serrated edges?

Combat knives have serrated edges primarily to increase their functionality and versatility in the field. Unlike smooth blades, the serrated edges are designed to cut through harder materials. They act like a saw, allowing the user to apply less force when cutting through tough or fibrous materials such as rope or bone.

In survival situations, these serrations can prove invaluable, facilitating tasks such as building shelters or processing food. Furthermore, the serrations on a combat knife also serve a tactical purpose. When used defensively, the serrated edge can inflict more damage than a straight-edged blade, making it a formidable tool in a combat scenario.

Why are rescue knives serrated?

Rescue knives have serrated edges primarily because of their superior cutting power. The serrated design allows the knife to cut through tough or fibrous materials more efficiently, which is critical in rescue situations where time is of the essence.

These knives are often used to cut through seat belts, ropes, or heavy clothing to free individuals in distress. The serrations on the knife also stay sharp longer than a straight-edged knife, making it more reliable and durable.

Hence, the rescue knives have serrated edges to ensure quick and efficient performance during critical rescue operations.

Is a tactical knife serrated?

A tactical knife is a versatile tool for various applications, including self-defense, outdoor survival, and everyday utility. One frequently asked question about tactical knives is: do tactical knives have serrated edges? The answer depends on the knife’s specific model and intended use. whether they. The answer

Some tactical knives feature a fully serrated edge, others may have a partially serrated edge (also known as combo edge), and some come with a plain edge. Serrated edges are excellent for cutting through tough materials like rope or branches, thus making them an integral part of the knife’s functionality in certain situations, I have.

However, they can be harder to sharpen than plain edges. Consequently, the choice between serrated and non-serrated tactical knives largely depends on the user’s preference and required tasks.

What is the difference between a serrated knife and a carving knife?

The key difference between a serrated knife and a carving knife is its design, intended use, and cutting technique. A serrated knife, characterized by its saw-like edge, is designed to cut through soft or tough foods without damaging their interiors.

It’s excellent for slicing bread, tomatoes, or other foods with a hard exterior and soft interior. On the other hand, a carving knife, with its long and thin straight blade, is primarily used for slicing thin cuts of meat. This knife provides precise control and makes cleaner cuts compared to a serrated knife.

Therefore, the difference between serrated and carving knives is based on their specific culinary uses and design features.

Wrapping Up

Understanding when to use the serrated edge on a survival knife is crucial for anyone venturing into the outdoors. The serrated edge of a survival knife is primarily designed for tasks that require aggressive cutting, sawing, or ripping through materials. It is particularly effective when dealing with fibrous materials like ropes, branches, or animal hides.

The serrated edge applies pressure on the serration points, which pierce the material. The gullets (spaces between the points) see through the material as the knife is pushed or pulled. This makes the serrated edge an excellent choice for cutting through hard exterior and soft interior materials such as wood or bone.

However, they are unsuitable for tasks requiring precision or clean cuts, like skinning games or slicing food, where a plain edge would be more appropriate.

In conclusion, understanding when to use a survival knife’s serrated edge can significantly enhance one’s efficiency and safety in survival situations. Knowing its specific uses can help one leverage its benefits while avoiding potential drawbacks.
