The Flin platform was originally introduced with a sheepsfoot blade profile designed around precision, controlled cutting, and maximum visibility of the cutting edge. That concept became the foundation for the Flin SF, a compact fixed blade focused on everyday utility and detailed work.

With the introduction of the Flin DP, the platform expands to include a classic drop point profile. While both versions share the same compact dimensions, construction philosophy, and carry system, they offer different working characteristics. The sheepsfoot excels in precise and controlled cutting tasks, whereas the drop point provides greater versatility, a stronger tip, and improved penetration capability while maintaining excellent cutting performance.

MK’s philosophy for the Flin platform focuses on practical blade geometries paired with steels that are effective in use and easy to maintain—durable, corrosion-resistant, and dependable in everyday environments. While current editions highlight premium steels such as M390, the platform remains open to future development. As with other MK Knives & Tools projects, future Flin models may appear in additional blade profiles and steel variants, offering users different performance characteristics while preserving the core design philosophy of the MK-09 platform.

Grinds – Selected for Cutting Performance

Flin inherits MK’s characteristic emphasis on grind quality. Because the knife is designed as a high-performance EDC, the choice of grind is intentional and selective. Depending on the specific execution, Flin may feature:

• FGG – Fine Groove Grind (hollow) for exceptional cutting aggression and long-lasting sharpness,

• Full Flat Grind for balanced slicing and strength,

• Refined hybrid variations tailored to the blade’s thickness and intended purpose.

The thickness itself is deliberately chosen to maximize cutting efficiency relative to the knife’s compact form, ensuring that each grind variant performs at a high level.

Details of the Edge – False Edge and Jimping

To enhance penetration, reduce drag and maintain the knife’s agile character, Flin incorporates a false edge on select versions. This upper bevel contributes to a slimmer tip geometry without sacrificing strength. Just behind it, carefully cut jimping provides tactile feedback and stability during precision cuts. The jimping is crisp yet comfortable, allowing controlled thumb placement without creating hotspots.

Handle Design – Secure, Natural, Protective

The handle of the Flin continues MK’s approach to ergonomic minimalism. It is slim, tightly contoured and shaped to offer a secure, instinctive grip. A key element is the front profile that shields the hand and prevents slipping toward the blade, providing safety even in demanding tasks or when working with wet or cold hands.
Materials will vary, embracing the full MK diversity:

• G10,
• micarta,
• carbon fiber,
• FatCarbon, and additional materials in future limited runs.

Each material is selected not only for aesthetics, but for grip, comfort and durability in everyday carry conditions.

Construction – Compact Strength

Flin is built around a solid internal tang that ensures rigidity without compromising the knife’s lightweight profile. The scales are precisely fitted and screwed into position, forming a unified structure where ergonomics, geometry and balance work together. The knife’s center of mass is tuned to support quick, controlled movements, making it feel lively and responsive in the hand.

Carry System – Adaptive and User-Focused

Every Flin comes equipped with a custom-fitted Kydex or Holstex sheath designed to lock the knife in place with crisp, dependable retention. The sheath provides a slim, streamlined profile that fits naturally into an EDC setup without unnecessary bulk.

As standard, each sheath is paired with an UltiClip Slim 3.3, allowing the knife to be carried securely on a belt, pocket edge, backpack strap or inside the waistband. The UltiClip ensures a strong, stable hold even on thin fabric, making Flin exceptionally versatile right out of the box.

While the sheath form itself remains consistent, carry preferences are intentionally left to the user. The system supports full modularity—orientation, attachment hardware and carry style can be reconfigured to match personal habits or the environment. Whether vertical, horizontal, inverted or discrete deep-carry, the knife adapts seamlessly.

This flexibility reflects MK’s design philosophy: a knife should not dictate how it must be carried. Instead, each user should be able to tailor their setup without compromising safety, retention or the knife’s compact profile. Flin’s carry system encourages exactly that—customization, confidence and complete everyday readiness.
