How to Disarm a Knife Wielding Attacker

Learn how to disarm a person when you are unarmed.

Weapon disarms training uses defense against knife attacks. This is because they are the most difficult common weapon to disarm, but you can adapt these knife disarm techniques to other weapons also.

Warning: All fighting is dangerous. Fighting someone with a weapon is very dangerous. If all your attacker wants is money, it is much wiser to give it to him/her and/or run away than it is to protect your pride.

Low Weapon Defense

Only attempt these weapon defense techniques if you have no other choice—in a surprise attack, for example. 

Even if you have weapon defense training, chances are you’ll get injured. It’s much safer to run, comply, or find your own weapon. However, when those options are not feasible, these techniques may save your life.

This specific knife defense technique is for any weapon attack that comes in below the 90-degree point of the attacker’s elbow. The type of grip, the side, or the exact angle he strikes from don’t matter.

Limiting your choice of techniques makes your reaction time faster.

As the strike comes in, engage his arm with a cross-block. Point both your thumbs down so it’s harder for the knife to slip through. Keep one hand high and one low to “surround” his elbow.

High Weapon Defense

The high weapon defense is knife defense training for any attack that comes from above the 90-degree point of the attacker’s elbow.

As one of these knife attack techniques comes in, direct a modified elbow burst into the shoulder/upper part of his striking arm. 

Modify it by having your lead hand on your forehead as opposed to the top of your head. This lowers your elbow so that you won’t push him back as much when you collide into him. 

Shove your arms over his shoulder.
