Roxon FLEX Modular Multi-Tool – Test and Experiences
Multitools are plentiful, but what if you only want to carry the tools you really need? That's exactly where the Roxon FLEX Modular Multi-Tool comes in.
I tested the Flex Modular (the version without pre-installed tools) extensively and found out how this innovative concept performs in practice. Does the Roxon FLEX deliver on its promises? Find out now!

What you get – Scope of delivery
The Roxon FLEX Modular Multi-Tool comes in a " frame only " version, ready to be customized to your needs. The scope of delivery includes:
- Roxon S804 Flex Core Multitool (frame without pre-installed tools)
- Robust nylon holster with belt loop
- Allen key for adjusting the screws
- Interchangeable cutting inserts for the pliers
- Detailed instructions for use

My first impression
From the moment you unpack it, the Roxon FLEX Modular Multi-Tool makes a high-quality impression. The rounded edges ensure the tool sits comfortably in your hand —nothing presses, bothers, or feels cheap.

The weight is noticeable, but not annoying—quite the opposite: It underscores the quality and robust workmanship. I was particularly impressed by the well-thought-out construction, with nothing wobbling or poorly crafted.
Another plus point: the included carrying case is made of sturdy nylon, which, thanks to the belt loop, is ideal for travel. The 25-year manufacturer's warranty also testifies to the company's confidence in its quality.

I was curious to see how the Roxon FLEX would perform in practice, and whether it really is as flexible and versatile as it promises.
Your multitool, your rules
The flexibility begins with the purchase: You decide which tools you need. On the official website, you can choose from a wide variety of modules – from tools for outdoor adventures to specialized tools for anglers or cyclists. In my opinion, this is one of the best features of the Roxon FLEX and one of the reasons why I chose this tool.

Details & Features
The Roxon FLEX Modular Multi-Tool is designed for maximum adaptability. Here are its key features at a glance:
- Modular design: Each side of the tool offers space for five slots, which you can configure as you wish. However, be careful: Some tools require more than one slot.
- Precision manufacturing: Each module is manufactured to a tolerance of 2 micrometers – a standard that ensures the highest precision.
- Easy assembly: Tools can be installed and removed quickly and effortlessly by hand, without any additional tools.
- Integrated safety mechanisms: A sophisticated lock prevents accidental opening, while a sliding bolt provides additional security.
- Material quality: Made of 2Cr13 and 3Cr13 stainless steel, sturdy and durable, with rounded edges for maximum comfort and ergonomics.

Tool assembly step-by-step

How it works:
- Select the desired tool.
- Push the safety lever all the way down.
- Hook the tool in completely.
- Move the safety lever back to the middle position.
- Check the locking mechanism – the safety mechanism ensures that the tool does not fall out during transport.
- Done – ready to use!

Practical test
How does the Roxon FLEX perform in use?
I've taken the Roxon FLEX with me on several trips, and it has never disappointed me. I'd like to highlight the following tools and situations :
- Pliers: Fits comfortably in the hand, allowing for a firm grip even with hard materials. The front section is serrated, tapering towards the tip. This is ideal for precise work. The middle section of the pliers is suitable for loosening nuts, etc. It is also serrated. Below this is the cutting section, whose blades are replaceable when they become blunt.

- Knife: Razor-sharp, cut through rope with ease, and performed well when carving. Also perfectly suitable for small tasks at home, such as opening packages or cutting rope, in the EDC category.

- Saw: In our tests, it proved to be very effective and, above all, sharp. The teeth grip the wood securely and allow the saw to cut quickly through branches. I used it in the hunting area to remove branches in front of a tree stand that were restricting access.

- Philips screwdriver : Sturdy, precise , and a real helper for quick repairs . I was able to tighten a loose screw on my fishing reel with it and didn't have to cut my fishing trip short.
My conclusion
The flexible future of multitools

The Roxon FLEX is more than just another multi-tool—it's a small revolution in terms of adaptability and quality. Its modular design lets you decide what you need. Robust construction, sophisticated safety mechanisms, and great handling make it a viable alternative to classics like Leatherman and the like. A clear recommendation from Fang-Fieber!
