Designed around the way people actually use their everyday carry tools, the OKNIFE MK 3-in-1 Multi-Tool brings a flashlight, folding blade, and screwdriver together in one compact utility tool weighing just 52 g (1.83 oz).
One tool. Three everyday functions. Designed to work together.
Why We Created MK
Everyday carry has become a collection of separate tools.
A flashlight for when you need to see. A blade for everyday cutting. A screwdriver for quick fixes. Each solves a different problem, and for many people, all three have become familiar parts of daily carry.
But as more tools find their way into our pockets and bags, they create a new problem of their own: more to carry, more to organize, and more to switch between.
Through conversations with our community and by observing how people actually use their EDC gear, we kept coming back to the same question:
Could one tool do more?
That question became the starting point for MK.
We brought three frequently used everyday functions — light, blade, and screwdriver — together in one compact utility tool. But simply putting three tools into one body wasn't enough.
We wanted them to work together.
When you're cutting or using the screwdriver, MK's integrated light can illuminate the working area directly. There's no need to hold a separate flashlight in your other hand or stop what you're doing to reposition a light source.
That's the thinking behind MK: not carrying more functions for the sake of having more, but making the tools you already use simpler to carry and easier to use together.
Carry Less. Do More.
Three Essential Functions in One EDC Tool
Light — 300 Lumens When You Need It
MK delivers up to 300 lumens from its main light, with a maximum throw of 133 m (436 ft).
For closer work, the side light provides softer illumination at short range, while the red light offers another lighting option for low-light situations.
With a maximum runtime of up to 18 hours, MK is designed to handle both quick tasks and longer periods of everyday use.
The included 3.6V 10440 Li-ion battery, 450 mAh is rechargeable via USB-C for convenient everyday charging.
Cut — A Compact 9Cr18MoV Blade
MK uses a 9Cr18MoV stainless steel blade rated at 58±1 HRC.
At 48.5 mm long and 2 mm thick, it's sized for common everyday cutting tasks such as opening packages, cutting tape, and trimming materials.
The blade uses a slipjoint mechanism, which provides spring resistance but does not lock the blade in the open position.
Fix — A Folding 4 mm Bit Driver
MK's folding screwdriver uses a magnetic 4 mm bit holder and comes with an S2 steel PH0 / SL3.5 double-ended bit.
The magnetic design makes the bit simple to install and remove, while compatibility with other 4 mm bits provides flexibility for different small tasks.
The screwdriver is intended for light-duty adjustments, such as small household items, toys, and compact electronics. It is not designed to replace a full-size screwdriver or handle heavy-duty repairs.
How MK Fits Into Everyday Tasks
The value of a compact EDC multi-tool becomes clearer in the small situations that happen throughout the day. MK brings practical functions together so you can move between tasks without switching tools.
1. Opening Packages in Low Light
Whether you're opening a delivery in a dimly lit garage or unpacking equipment after dark, MK lets you illuminate the cutting area while using its folding blade. The integrated light helps you see what you're working on without holding a separate flashlight.
2. Making Small Everyday Adjustments
Loose screws on small household items, toys, or compact accessories can be handled with MK's folding bit driver, provided the included bit fits the fastener and the task requires only light torque.
When lighting is limited, the integrated flashlight can help illuminate the working area.
3. Keeping Essential Tools Close at Hand
At just 52 g (1.83 oz), MK can be clipped to a pocket or bag for convenient access. Instead of carrying a separate compact flashlight, folding blade, and small screwdriver for routine tasks, MK combines their core functions into one tool.
MK vs. Carrying Separate EDC Tools
Separate tools remain useful, especially when a task requires specialized performance. MK takes a different approach by combining essential light-duty functions in a compact everyday carry format.
| Feature | OKNIFE MK | Separate Tools |
|---|---|---|
| Core functions | Light, blade, screwdriver | Individual functions |
| Carry format | One compact tool | Multiple items |
| Integrated lighting | Can illuminate blade and bit-driver tasks | Usually requires separate positioning |
| Weight | 52 g (1.83 oz) | Depends on selected tools |
| Best suited for | Compact everyday tasks | Specialized or demanding tasks |
Designed to Work Together
The biggest difference isn't simply that MK includes three functions. It's the way those functions work together.
Turn on the light while using the blade to illuminate a cutting area. Use the light while working with the screwdriver in a dark or tight space. Move from one task to another without reaching for another tool.
By bringing light, cut, and fix into one compact platform, MK helps reduce the amount of gear you need to carry while keeping everyday functions close at hand.
52 g — Made to Stay With You
Combining multiple functions only makes sense if the final tool still feels easy to carry.
MK weighs just 52 g (1.83 oz), making it easy to clip to a pocket, bag, or everyday carry setup without adding much weight.
Built for Everyday Use
MK is rated IP65 and has passed a 1-meter drop test, providing additional durability for regular everyday use.
Its recommended operating temperature range is 0–40°C (32–104°F).
Whether it's clipped to a pocket, stored in a bag, or kept nearby at a workspace, MK is designed for the small tasks that come up throughout the day.
