Collection: Self Defense Keychain Knives

About Keychain Knives

Keychain knives are handheld self defense weapons with sharp blades that are designed to be discreet, concealed, or hidden keychains.

Keychain Knife Origins

Keychain knives were created in recent time when pocket knives began to be produced in large numbers and became popular with hunters, campers, fishermen, and outdoor adventurers. Using these knives in mass and frequently naturally led to making them more practical by attaching rope and keychains so they could be attached to ones belt loop or keys.

Keychain Knife Materials

Keychain knife blades are made from high quality materials that are durable and long-lasting. They are generally made from strong metals such as stainless steel, known for its durability, corrosion-resistance, hypo-allergenic properties, and sharp edges. Keychain knives are made from other materials such as carbon steel, titanium, ceramic, aluminum, plastic, brass, and copper.

Keychain Knife Shapes and Sizes

Keychain knives come in different shapes and sizes depending on the needs of the user. The blades can be beveled, serrated, pointed, or hooked which allows for different functions. Beveled blades contain sharp edges that can slice or cut. Serrated blades contain jagged teeth that can saw through materials like rope or zip ties. Pointed blades allow the user to stab and poke. Lastly, hooked blades are curved at the tip allowing the user to grab, grip, or hold things.

Discretion of Keychain Knives

All keychain knives are closed blades meaning that you can't hurt yourself with the blade unless the knife is open. Many keychain knives are also concealed, hidden, or discreet, meaning that they take the appearance of another item when in fact they are knives. For example keychain key knives look like ordinary house keys but can be unfolded and turned into a self defense weapon. Other keychain knives look like capsules or containers, and can be unscrewed to unsheathe the blade portion.

Key Knife Uses

If you are being attacked by a predator using deadly force and you need to use your key knife as a last resort for protection, there are many different techniques and strategies you could use to deter them.

  • Using the knife to create distance since the attacker will not want to get close for fear of being cut
  • Holding the knife and engaging in rapid, unpredictable movements to disorient the attacker and scare them off
  • Using the knife to create a distraction by throwing it in the air, on the ground, and cutting or breaking a nearby object to intimidate the attacker
  • Using the knife in a forward thrusting motion
  • Using the knife in an overhead hammer-strike motion
  • Defending yourself against the knife by targeting the attacker's hands or offensive strikes
