 Emergency Self-Defense
for  Extreme  Self-Defense Situations

An extreme self-defense situation exists in...

Superiority of the aggressor (stronger, armed, more numerous)

NO POSSIBILITY of avoidance, de-escalation or escape.

In this extreme situation, the palm stick / kubotan is your "emergency hammer" with which you can compensate for the aggressor's superiority.

Using the palm stick as a striking amplifier, you can neutralize the aggression and enable your escape.

Notfall-Selbstverteidigung...

...für ExtremSituationen.

Eine Extrem-Notwehrsituation besteht bei...

ÜBERLEGENHEIT des Aggressors (stärker, bewaffnet, in Überzahl)

KEINE MÖGLICHKEIT der Vermeidung, Deeskalation oder Flucht.

In dieser Extremsituation ist der Palmstick / Kubotan Dein "Not-Hammer", mit dem Du die Überlegenheit des Aggressors ausgleichen kannst.

Mit dem Palmstick als Schlagverstärker, kannst Du die Aggression neutralisieren und Deine Flucht ermöglichen.

"A very well-structured course"

Mike from Leipzig, Germany

A compact self-defense concept without unnecessary frills!

It compensates for physical "inferiority"—provided the mind is stable and focused (in a self-defense situation).

I'm familiar with several online courses. This is one of the few that I can wholeheartedly recommend! Clearly structured. Comprehensive but not overwhelming. Everything is easy to understand and implement because it's explained simply and logically organized.

This is a system that can be used intuitively. If I have to think in a self-defense situation, I've already lost. It's also perfect for people who primarily train solo.

5 stars.

What an amazing concept!

The instructor explains the techniques very clearly and understandably. The demonstrated palm stick defense is highly effective, and because the techniques are so simple and natural, they are easy to recall, even under stress.

Palm stick, kubotan, tactical pen, flashlight, cell phone, newspaper—whatever you have with you, if you learn from these palm stick online course videos, you can defend yourself with anything!

A highly effective self-defense system using very few and simple techniques. The techniques are demonstrated in great detail and are easy to remember. The entire course is incredibly comprehensive, and it's fun to train with.

Kai developed this highly effective concept, which he explains superbly in this online course and which is quick to learn. The combination of attending the seminar and the online course has made this method incredibly beneficial for me!

I found the online course extremely helpful.

Online self-defense courses may be somewhat controversial. However, if you have the opportunity to train with a partner, such a course provides valuable insights.

The structure of the palm stick course is excellent. Kai Kühn explains the various techniques superbly. I think even beginners can benefit from the course.

The great thing is that you can log back into a specific topic at any time and refresh your knowledge. The techniques are quick to learn and, I'm convinced, can be executed without much thought in a real-life situation. Fortunately, I've never had to prove that yet...

I always carry a pen in my jacket.

Perfect course, absolutely nothing to complain about.

The course is perfectly structured, the videos have excellent picture and sound quality, and last but not least, the techniques are explained very precisely, clearly, and in detail.

Thumbs up, I'd love to see more courses like this...

This is a very well-structured course that leaves no questions unanswered. It's an uncompromising self-defense system, combined with fundamental theoretical and legal knowledge, and features outstandingly well-structured lessons.

As a long-time Escrima practitioner who has also led my own groups, I immediately felt comfortable and can highly recommend this course. Even beginners will find it beneficial.

Mike

The online course is fantastic.

The lessons are structured step by step. In the exercises, Kai repeatedly demonstrates the actions from different angles.

I watch some scenes several times so I can later incorporate them into my training.

I especially like the downgrade to unarmed practice.

I use this to refresh what I learned in Kai's Hammer Concept course.

Guido

Bornheim, Germany

I found the online course very well-structured and easy to follow.

Because the individual exercises were presented in a didactically sound and understandable way within small learning units, I was actually able to practice precisely on my own without a teacher present.

I would be pleased if similar courses with additional FMA content were offered in the future.
