1. Ka-Bar USMC Fighting Knife

The Ka-Bar USMC Fighting Knife is perhaps the most iconic military knife of the 20th century. Adopted by the United States Marine Corps in 1942, it saw extensive service in World War II, Korea, and Vietnam. The classic design features a 7-inch clip-point blade made of 1095 carbon steel, a leather-wrapped handle, and a steel guard. Modern production models, such as the Ka-Bar 1217, are still manufactured in the USA and retail for around $80–$120 (approximately €75–€110). In Spain, these knives are available through military surplus retailers like Barricada's guide to buying Spanish military gear online or international sellers on Amazon.es. The Ka-Bar is a must-have for collectors due to its historical provenance, and survivalists appreciate its robust build and ability to perform heavy-duty tasks.

2. Spanish Army M1926 Knife (Cuchillo de Campaña)

The M1926, also known as the Cuchillo de Campaña, is a classic Spanish military knife that served from the 1920s through the Spanish Civil War and beyond. It features a 6.3-inch (16 cm) blade with a distinctive spear-point shape, a brass guard, and a wooden handle. Original examples are highly sought after by collectors, often fetching €150–€300 depending on condition. However, modern reproductions are available from Spanish manufacturers like Marto or Denix, priced around €40–€80.

3. OKC-3S Bayonet (M9 Bayonet)

The M9 bayonet, produced by Phrobis and later Ontario Knife Company (OKC), is a multi-purpose knife designed for the M16 rifle. It features a 7-inch blade with a wire-cutter capability when used with its scabbard. The OKC-3S variant is the current US military issue. These bayonets are widely available on the surplus market, with prices ranging from $60–$100 (€55–€90). In Spain, they can be found at militaria fairs or online stores. Collectors value the M9 for its technological innovation, while survivalists appreciate the sawback edge and sturdy construction. Pairing this knife with a proper military rucksack ensures you have a complete field kit.

4. Fairbairn-Sykes Fighting Knife

Developed for British Commandos during World War II, the Fairbairn-Sykes (F-S) fighting knife is a stiletto-style blade designed for thrusting. Its narrow, 6.5-inch blade and iconic handle shape make it instantly recognizable. Original Second World War models are rare and expensive, often exceeding €500. Modern reproductions by companies like Sheffield Knives or Windlass Steelcrafts cost around €80–€150. The F-S knife is primarily a collector's item due to its specialized design, but survivalists may find it useful as a fine-point tool.

7. Cold Steel SRK (Survival Rescue Knife)

While not a military-issue knife per se, the Cold Steel SRK is widely used by military personnel and survivalists.

When building a survival kit, consider pairing the SRK with a military-style backpack for optimal load distribution.

How to Choose a Military Knife

When selecting a military knife, consider the following factors:

  • Intended use: Collectors prioritize historical accuracy and condition; survivalists need durability and edge retention.
  • Legality: In Spain, carrying knives with blades longer than 11 cm (approx. 4.3 inches) in public is restricted. Always check local laws.
  • Steel type: Carbon steel (e.g., 1095) is easier to sharpen but rust-prone; stainless steel (e.g., 440C) resists corrosion.
  • Handle material: Leather, wood, and polymer each offer different grip and durability.
  • Budget: Prices range from €30 for modern production knives to over €500 for rare originals.

Maintenance and Care

Proper maintenance extends the life of your knife. For carbon steel blades, apply a thin coat of oil (e.g., mineral oil or Ballistol) after each use. Store knives in a dry environment, preferably in a sheath that allows airflow. Sharpen regularly using a whetstone or guided system. For leather handles, avoid soaking in water; clean with a damp cloth and condition with leather balm. Wooden handles may require occasional oiling to prevent drying.
