• Advantages: Robust, ideal for drilling and heavy-duty tasks.
• Disadvantages: Less versatile for precision tasks.

Trailing Point blade

The trailing point blade is ideal for cutting and skinning tasks. It features a raised tip, offering a large cutting surface.

• Advantages: Large cutting surface, ideal for skinning.
• Disadvantages: Less robust for heavy-duty tasks.

4. Handle and Ergonomics

Handle materials

The survival knife's handle should be comfortable to hold, even in wet conditions. Commonly used materials include:

• G10: A tough, lightweight fiberglass composite.
• Micarta: A composite material made of cloth or paper, offering good grip and durability.
• Rubber: Offers excellent grip, even in wet conditions.
• Wood: Aesthetic and comfortable, but may be less durable in wet conditions.

Ergonomics

Handle ergonomics are crucial to ensure optimum comfort and control when using the knife. Look for handles with ergonomic shapes, finger grooves and non-slip textures. Some models also feature handguards to prevent your hand from slipping on the blade.

5. Specific features

Case

A good sheath is essential for carrying and protecting your survival knife. Look for sheaths made of sturdy, water-resistant materials, such as ballistic nylon or Kydex. The sheath should be equipped with secure fastening systems, such as buckles or clips, for easy and safe transport.

Firelighters

Some survival knives feature an integrated fire starter, enabling you to start a fire in an emergency. This feature is particularly useful for outdoor activities and survival situations.

Glass breakers and belt cutters

Window breakers and belt cutters are additional features that can be useful in emergency situations. Glass breakers can be used to break car windows in the event of an accident, while belt cutters can be used to quickly cut seat belts.

Emergency whistle

Some survival knives feature an integrated emergency whistle, allowing you to signal your position in an emergency. This feature is particularly useful for outdoor activities and survival situations.

6. Durability and care

Durability

The durability of a survival knife depends on the materials used in its construction and the quality of manufacture. High-quality stainless steel or carbon steel blades offer great durability. Handles made of sturdy materials, such as G10 or Micarta, offer good resistance to wear and tear.

Maintenance

Proper care extends the life of your survival knife. After each use, clean the blade and handle with mild soap and water, then dry thoroughly. Apply a thin layer of oil to the blade to prevent corrosion. Sharpen the blade regularly to maintain optimum cutting edge.

Choosing a survival knife is a crucial decision for outdoor enthusiasts, hikers and adventurers. By considering knife types, blade materials, blade design, handle and ergonomics, specific features and durability, you can find the ideal survival knife for your adventures. Don't forget to check compatibility with your other equipment, and to test the knife in conditions similar to those you'll encounter on your outings. With the right survival knife, you'll be able to enjoy every adventure to the full, safely and with optimum performance.
