INFI is a name. 
Behind this name is your skill. 
No matter who you are and what you have learnt.
INFI is your skill.

The INFI Method


The INFI Method is the empty-hand branch of SFS and its most unique part. INFI stands for Individual Fighting—a way to develop your own natural style rather than copy someone else’s.


Unlike traditional martial arts, where everyone must move the same, INFI focuses on the individual. Your body type, reflexes, mindset, and strengths shape your path. The method provides guidance and structured challenges, but the solutions are yours.


In practice, this means no fixed forms or ideal techniques. INFI demonstrations never aim for visual uniformity—they reveal how effectively someone can solve a situation in real time. The measure of progress is not appearance, but efficiency.


The trainer’s role is not to be a model to imitate but a guide, like a road sign or a runway light. They help you find your own way. Progress comes fast: what may take years in traditional systems can be achieved in months with the INFI Method.


The foundation of INFI is the combination of:

• The individual with all their unique traits

• Universal laws of physics and anatomy

• Realistic situations that bring out hidden potential


Through structured exercises, partner work, and practical scenarios, practitioners develop confidence, awareness, and the ability to respond effectively under pressure.


The foundation of the INFI Method is the vulnerability to crime and physical violence. Its essence lies in providing guidance through instructions and enabling experience through continuously intensifying situational exercises.

The INFI Method is not about tradition, rituals, or sport competition. It is about survival, adaptability, and personal mastery. Its truth is simple: every person is a style.

Individual styles behind traditional styles

Date:

non-traditional kick Creating our individual style is a natural process. Everyone develops their style automatically. This statement is general but can be applied to any specific field—martial arts, combat sports, and self-defence are no exceptions. People who practice fighting are constantly creating their own fighting styles. They are, consciously or unconsciously, the creators of their unique approach to combat. Whatever one is learning, only a part of it will truly be absorbed. Another part will be automatically rejected by the self. Moreover, every absorbed element is filtered through a person’s individuality. The evolving individual fighting style becomes distinct from the traditionally practiced style. In other words, by practicing conventional techniques, one is also developing an invisible, personal fighting style—what we can call the InFi style. For example, someone studying Wing Chun kung fu or Kyokushinkai karate is guided by teachers and improved within the framework of tr...

Welcome to the Percomboo World The Percomboo World is a unique educational system focused on developing individual competencies and personal styles. At its core, Percomboo is built on three foundational pillars: Philosophy - Mental Psychology - Emotional Drills, Martial Art - Physical While technical  M artial Art  appear on the symbolic surface of our world, they serve more as a lens through which we explore deeper ideas. A Modern, Global Approach In recent decades, the internet has radically transformed the way we access information, build knowledge, and share ideas. As a result, personal development has become increasingly individualized—and naturally so. Percomboo embraces this shift by supporting individual differences . We don't promote a single "right" way to learn or grow. Instead, we believe your way is the best way—for you . Our role is to help you discover, develop, and refine that way. How We Teach Our method follows a simple yet powerful framework...

Bruce Lee paradox

Date:
Image
Yesterday, I raised the question of whether Bruce Lee was right or wrong when he said, "I do not believe in styles." The basis of this question lies in the well-known fact that styles do exist and have continued to thrive ever since he made that statement in a 1971 interview. It seems that his claim has had little effect on the popularity of martial art styles, even though Bruce Lee remains the most famous, influential, and legendary martial artist of all time. Millions of Bruce Lee fans and followers continue to practice one or more traditional martial art styles. In fact, many beginners—initially inspired by Bruce Lee—end up learning and devoting themselves to traditional styles. As a result, a certain contradiction becomes apparent, and the question is entirely justifiable. Now, I’d like to share my friend Milagros’ great response to that question: “The Dragon is right; people should not rely on style. People try to keep an open mind—I believe this is what the Dragon wan...

InFi and MMA

Date:
Image
Some days ago, I had a conversation with a martial arts expert about individual fighting. After my first two sentences, he said, “Aha, then it’s similar to MMA, isn’t it?” “Yes, in some respects it is,” I replied, “but in many essential ways, it definitely is not.” In columns, I listed their attributes. To make the picture even clearer, I began with the well-known concept of freestyle. None of these are classical styles. I highlighted the similarities to InFi in green, and the differences in pink. Each line represents the same aspect across all columns. In summary, we might call MMA a sport version of InFi—or restricted individual fighting . But we must not refer to InFi as free MMA in general, because the restrictions in MMA are not merely technical. The entire mindset is different. The most essential discrepancies lie in the third, fourth, and fifth lines above—which are not about freedom or limitation at all. Of course, every MMA fighter has their own InFi outside of competiti...

Strength of Repetition

Repetition, Individuality, and the Formation of InFi Repetition is a fundamental part of the learning process. Every martial art and combat sport system uses it as a core teaching method — and for good reason. This principle is widely accepted and understood. But it raises an important question: To what extent can repetition shape our individual style? The answer: Only partially . Because repetition — no matter how intense or prolonged — can’t completely override our natural endowments. Your InFi (Individual Finesse) is deeply rooted in who you are. Training can shape and refine it, but it can’t erase it. The Illusion of Uniformity Imagine a group of people practicing the same movements repeatedly — a karate team performing synchronized katas or Shaolin monks drilling the same techniques thousands of times. Now picture yourself as their assistant or instructor. You know each person well. One day, they all wear identical uniforms and masks. Suppose their height and body type are also s...

Interest in martial arts is declining?!

Date:
Image
There is plenty of evidence that interest in martial arts has been declining over the last decade. This is apparent, and I believe the reasons are the internet, globalization, and changing trends. People who are drawn to combative activities and want to explore and develop their own InFi style simply don’t stay in schools for long. They train for a while and then move on. The internet opens the eyes of the open-minded. You can watch anything you want online, and masters can no longer keep their secrets the way they could 30 years ago. As a result, teachers are no longer seen as authority figures; they’ve become more like customer service providers. Changing trends are another factor. The popularity of martial arts fluctuates. MMA, Krav Maga, and tricking are the current trends. In my opinion, it’s just fashion. The fact that these are popular doesn’t mean they’re better—they’re simply newer and heavily promoted through the media. When it comes to individual fighting styles, some tr...

Styles Spread or Concealed

Date:
Image
Since there is no ultimate truth in this world, there is no perfect style to take on or put on. Styles are born and attached to individuals. As the InFi philosophy says, everybody has a different individual fighting style. Therefore, InFi styles have owners. In short: one person — one style. Ideally, then, there should be as many styles in the world as there are human beings. But the world doesn’t reflect this. There are major styles (trends) and minor styles. Some are popular, some are stagnant, and some disappear. Classical (traditional) systems are always struggling to gain ground, striving for popularity. Hidden traditional methods may even be in danger of extinction. traditional and InFi styles Classical or traditional ways are products—like cars, houses, or fashion trends. People pick them up from outside sources. Classical styles are not people's inborn or self-created ways; therefore, they can be sold. If you pay attention to the martial arts or combat sports world, you can...

Natural Style (karate-InFi)

Date:
Image
(karate) InFi by Tanaka Have you ever noticed that many karate practitioners' styles look completely different in a real fight compared to traditional karate? Have you ever observed that during spontaneous free fighting, it's nearly impossible to guess a competitor's traditional style—unless it's already known? Isn't it interesting how the structured, classical styles often seem to evaporate in real combat? The reason is simple: unpredictable situations are the domain of InFi . No external system has dominance over the power of InFi in that space. My friend John once said that the body reacts naturally using movements and techniques that have been instilled over time. That’s true. It’s the result of learning—repetition creates automatic reactions. But does that directly connect with the personal style I’m talking about? Yes, but only partially. Part of an individual's style is learned—copied or invented—and the other part is inborn. I would say the base of a...
