Knives are scary.

They are cheap.

They are easy to conceal.

They require zero training to be deadly.

And worse yet, they can kill anyone.

Case in point:

Cash App creator Bob Lee was fatally stabbed multiple times — including in the heart — while out late in Downtown San Francisco.

In Washington, D.C., a man was knifed to death by an acquaintance while using a computer in a public library — as children watched just a few feet away.

And in a Minnesota high school, a 16-year-old fatally attacked another student, piercing his stomach, chest, and heart.

The point is ...

Anyone can be deadly with a knife, anywhere at any time.

So, how do you train to stop a knife-wielding psycho?

The vast majority of knife seminars focus on ONE aspect of blade combatives: cutting up the bad guy.

These instructors only teach you what to do with the knife already in your hand. But that’s the EASY part.

The hard part is surviving long enough to get to your own blade in the first place!

So, our Knife Defense2 Seminar (pronounced "Knife Defense SQUARED Seminar") will offer practical and realistic training, such as knowing when and how to safely and quickly deploy your blade when you’ve been attacked. 

Our in-person program also includes emergency drills and worst-case scenarios, like what to do if you drop your blade or if the bad guy has gotten a hold of your weapon hand.

We’ll also take a deep dive into what you should do if a violent thug tries to shank you with a knife of his own and you haven’t gotten to your weapon yet (or aren’t carrying one).

Our innovative two-day seminar will also explore the ethics and legalities of carrying and using an edged weapon — a topic that most instructors fail to address ...

... but can dramatically affect your life after any violent encounter — legally, financially, and psychologically.

The Who

This program is for anyone who's serious about learning how to defend yourself against a vicious knife attack.

It's also for prepared and responsible folks who currently carry a blade or are looking into carrying a blade for self-defense purposes.

Also, this course will be a good refresher for law enforcement and military who might carry a blade as a backup weapon.

The When

This live and in-person event will take place on Saturday and Sunday, July 15-16, 2023.

We'll be training at the following times:


  • 3 p.m. to 6 p.m.


  • 9 a.m. to 12 p.m.
  • 1-hour lunch break
  • 1 p.m. to 5 p.m.

The Where

We will be training face-to-face in San Francisco at World Team USA, one of California's premier training centers for Muay Thai, Brazilian Jiu-Jitsu, Mixed Martial Arts, and more.

If you don't live on the West Coast, this is a great opportunity to pair up an innovative combatives event with a summer vacation in the Golden Gate City, where there are a ton of world-renown tourist attractions.

What Our Students Are Saying

Black Belt Magazine

"At Black Belt Magazine, we've been keeping an eye on Tiga Tactics for awhile now. Why? They keep bringing us the 'state-of-the-art' in self-defense and combatives programs."

Steve Myers

Former Federal Law Enforcement — Maryland

"The system is great how it builds from the basic to the more advanced. The classes that I had in the past were lacking in basic information, and rubber knives came out and "lets go at it!" No thought of what type of knife to carry and how to operate with it. In grading [this course] I give it 100%."

Steven Barlow

"Knives Illustrated" Editor — New York

"I can say that the skills taught here were very much in line with my experiences as a police officer. As a matter of fact, the technique taught here about striking at your attacker while stepping back to create the opportunity to deploy your knife was exactly what we taught our officers during firearms training in order to be able to draw our pistols. It can SAVE YOUR LIFE."

Paul Tirajoh

Martial Arts Instructor — Colorado

"With the combatives, movement, and accelerated heartbeat/duress thrown in during the class, I was finding that my successful deployments weren’t quite what I expected them to be. From partial deployments to straight up dropping my knife on the ground, knowing these failures and training them makes me feel much more confident and competent."

Matthew Baker

Firearms Instructor — Los Angeles

"The content was presented in a universal way that was accessible and beneficial to all skill levels. I loved the concept and approach to empty-hand combatives in a weapons-based environment, utilizing moves that have a high probability of success under stress and a low probability of injury."
