Mastering Tactical Knife Use: Understanding Primary Stopping Methods

In the realm of tactical knife use, understanding and mastering primary stopping methods are crucial for effective self-defense. Operating under the principle that the use of a knife is a last resort, these methods aim to debilitate the attacker's physical capabilities and emotional intent, ensuring the preservation of life and limb.

1. Psychological Stopping:

Psychological stopping power leverages the fear induced by the presence of a knife. It prompts the attacker to shut down mentally, driven by the fear of the knife itself or the shock resulting from any inflicted wound. The psychological impact plays a significant role in immobilizing the assailant.

2. Hypovolemic Shock:

Inflicting wounds that lead to severe blood and fluid loss, such as cutting major arteries like the Carotid artery, jugular vein, subclavian artery, axillary artery, descending aorta, or femoral artery, can induce hypovolemic shock. This emergency condition impairs the heart's ability to pump enough blood, causing multiple organ failures and incapacitating the attacker.

3. Damage to Major Organs:

Targeting vital life-supporting organs, such as the heart or lungs, can effectively incapacitate an attacker. Inflicting damage to these critical organs disrupts their function, leading to immediate incapacitation.

4. Damage to the Central Nervous System:

Aiming for the central nervous system—the brain stem and spinal cord—with precise knife techniques is an instantaneous method of incapacitation. Disrupting the central nervous system results in a rapid and effective stop, neutralizing the threat.

5. Structural Stops:

Strategic cutting of muscles and tendons serves to hinder or impair motor functions, providing tactical advantages. Specific targets include:

  • Cutting the inside forearm and flexor tendons on the wrist and hands to destroy grip.

  • Cutting the bicep and triceps to impede the coordination and motion of the weapon arm.

  • Cutting the quadriceps above the knee and the sides of the knee to disrupt the attacker's mobility, creating an opportunity to escape.

  • Cutting the Achilles tendon to affect the attacker's ability to walk.


Mastering these primary stopping methods requires precision, understanding anatomy, and training for efficiency. When faced with the necessity of using a knife for self-defense, practitioners of tactical knife techniques must be adept at choosing the appropriate method to neutralize the threat effectively and ensure personal safety.
