The atmosphere of the Westend Grand Prix is always challenging, but we know that a few minutes of rest can make all the difference between two intense bouts. We want to offer a comfortable spot for all participants to step back and find their focus.

Coffee & chat?

Whether you will be there to compete, coach, cheer, or simply watch the Grand Prix, we would love to welcome you at the Calibur booth! We will be there throughout the whole event, from March 13th to 15th. We'll create a dedicated space just outside the main competition area, where the air is a bit calmer and the coffee is on us. It’s not just a stand; it’s a place to catch your breath, recharge, and talk about the sport we all love.

See you at the BOK Hall!

We are excited to be part of the energy and the world-class fencing that the Westend GP brings to Budapest. If you find yourself needing a short break from the intense action on the piste, make sure to stop by our booth for a chat. While the results are what we all work for, let's also take the time to enjoy what brings us together: the passion for fencing (and perhaps a good cup of coffee in hand).

What Is It Like to Grow Up in The Slums?

Mburu grew up in one of Nairobi’s most challenging neighbourhoods. These areas face severe shortcomings: many homes are poorly built, sewage runs openly in the streets, clean drinking water is hard to find, and disease outbreaks are common. Economic life is uncertain: most people rely on informal, unstable jobs that pay far less than what would lift them out of poverty. In this context, young people have very few paths forward: schooling is often interrupted, work is scarce, and for many, joining local gangs or robbery groups seems like the only path available.

The Moment of Transition

At that time, Mburu also thought the streets were the only path he could take. During a robbery, Mburu was shot, which made him question the choices that had led him there. It became a moment of reflection and the start of a search for something different, something that could give his life meaning beyond the streets. Looking back, he said: „How I depicted it was that God has a purpose and a reason for me”. Later, he met Okalo, who introduced him to the world of fencing. Mburu trained with determination for months until he earned a scholarship to the FIE Coaching Academy. After completing his training, he resolved to help young people, to offer them the same opportunity that fencing had given him.

Books, Blades and Building Futures

Through Tsavora Fencing Mtaani, he built a safe space where young athletes could learn not only the technique of a parry or a lunge, but also the values that define true fencing spirit: discipline, respect, and integrity. Many of the young fencers he now trains come from the same kind of environment he once knew too well. As Mburu puts it: “They look at me and say, ‘If Coach Mburu did it, even me, I can do it.’” Those words drive his work every day. He also started a program called Books and Blades, aimed at helping young athletes not only in fencing but also in staying engaged with their education.

Through Tsavora Fencing, they’re organizing the first East African Champions Fencing League, a unique event that blends fencing and entertainment. But beyond the spectacle, they have a larger purpose: their goal is to revive regional fencing clubs in Rwanda, Kenya and Uganda. All proceeds from the event support under-resourced fencing clubs, providing young athletes with opportunities they might otherwise never have.

Fencing holds the power to change lives, even in places where the odds are stacked against young people. If you feel moved to help, and you’re able to offer support in any way (be it sponsoring the event, or the programs, donating equipment, or helping young athletes with learning opportunities) please reach out at the contact below.

When we soldered together the very first experimental pocket boxes in 2020, we weren’t sure what to expect. Would they even work on the piste? Those first field tests in épée and foil felt like a leap into the unknown — but when the lights came on and the system responded just as we hoped, we knew we were onto something special.

From that moment, the idea became a mission.

2022 - Gaining trust in the community

As word spread, two of the biggest names in fencing — PBT and Allstar — decided to carry our product. For us, it was more than just retail agreements; it was validation that even established players in the sport saw the value of what we were building. Ever since, Calibur is available in dozens of physical fencing stores worldwide.

2023 - Into the spotlight

The year brought challenges and big opportunities. We were invited to present our vision on Shark Tank, a nerve-wracking but unforgettable experience. Soon after, STRT Holding joined us as an investor. With their support and the community’s continued enthusiasm, sales soared into the thousands.

2024 - A breakthrough for sabre

Sabre fencers had been patiently waiting, and finally, the Gen2 Pocket Box delivered. Scoring was now possible without any extension kits — and we used the redesign to bring major improvements in accuracy, ease of use, and overall experience. It felt like a new chapter for our technology.

2025 - Connecting past and future

This year, we introduced the Relay: a bridge between tradition and innovation. For the first time, pocket boxes can connect to classic scoring machines, transforming them into wireless systems without losing the feel of tradition. It’s the clearest sign yet that our goal isn’t just to innovate, but to integrate.

Looking back, it’s incredible to see how far we’ve come in just five years. What started as a small experiment has grown into a movement, embraced by fencers across the world. And while we’re proud of what we’ve built so far, we know the journey is only beginning.

What's next?

We’re not stopping here. The next steps on our journey include introducing piste grounding, polishing accuracy in those specific edge cases for foil and sabre, and making our website available in new languages — so even more of the fencing world can connect with us directly.

Here’s to the next chapter.
