When power meets precision, you get the Tekto F3 Charlie — a tactical flipper knife engineered for those who demand strength, reliability, and smooth performance. Built for high-stakes tactical operations, this robust knife doesn’t just perform — it dominates. The F3 Charlie is more than a cutting tool; it’s a dependable companion designed for the mission-ready professional or the everyday carrier who refuses to compromise on quality.
Built for Action: Design and Engineering
The Tekto F3 Charlie is forged from the philosophy that performance and style should exist in perfect balance. With its Damascus-inspired G10 and Forged Carbon handle, it exudes a sleek and aggressive aesthetic while maintaining the durability and grip necessary for any environment. The handle’s ergonomic contours ensure a confident hold, even in wet or gloved conditions, and the anti-slip thumb jimping enhances precision when applying controlled pressure.
At its core lies a titanium-coated D2 steel blade, measuring 3.80 inches in length. This material choice ensures both exceptional edge retention and toughness, giving users the confidence to tackle anything from delicate slicing to heavy-duty cutting tasks. The titanium coating adds an extra layer of corrosion resistance and gives the blade its refined, tactical appearance.
Its button lock system offers rapid, secure deployment. With a flick of the flipper tab, the blade glides open smoothly, locking firmly into place with a satisfying click — ready for action in an instant. The precision-machined lock and pivot system keep the motion consistent and stable over time, ensuring this knife performs flawlessly through thousands of openings.

Real-World Cutting Tests
To evaluate the F3 Charlie’s real-world performance, we subjected it to a variety of challenging materials. Each test highlights the knife’s cutting prowess, edge retention, and ergonomic stability.
- Hair Shaving Test – Factory Sharpness
Right out of the box, the F3 Charlie exhibits a razor-sharp edge. A gentle swipe across the forearm easily shaves hair cleanly, without any tugging or hesitation. The titanium-coated D2 steel demonstrates impeccable sharpness and polish.
- Rope Cut Test – Strength and Edge Geometry
Cutting through thick nylon and paracord ropes revealed the blade’s slicing power. The fine edge drop point glided effortlessly, requiring minimal pressure to sever strands cleanly. Even after multiple cuts, the edge remained consistent and sharp.
- Denim Cutting Test – Everyday Durability
Tough denim can quickly dull an inferior blade, but the F3 Charlie’s D2 edge retained its bite. It sliced through multiple layers of denim in smooth, uninterrupted motions—proving its reliability for fieldwork and utility use.
- Cardboard Cutting Test – Repetitive Task Endurance
Cardboard cutting puts continuous strain on any blade. The F3 Charlie excelled, slicing through layered packaging materials with ease and maintaining its sharpness throughout prolonged use. The grip remained secure, with no slippage or hot spots.
- Paper Cutting Test – Fine Control & Sharpness
A gentle slicing motion through standard paper produced clean, feather-light cuts with no tearing or snagging. This test reaffirms the F3 Charlie’s precise edge geometry and consistent grind.
- Wood Shaving Test (Particle Board) – Utility and Toughness
When tested against particle board, the knife’s fine edge easily peeled controlled curls of wood, perfect for fire-starting or bushcrafting needs. The jimping provided added pressure control, while the blade resisted any rolling.
- Aluminum Can Cutting Test – Toughness & Durability
For the ultimate test of resilience, we sliced into an aluminum can. The F3 Charlie managed to pierce and slice the metal without deformation, showcasing both toughness and precise edge retention.
Performance and Handling
In hand, the Tekto F3 Charlie feels both balanced and assertive. Despite its full 9-inch open length, it remains lightweight enough for comfortable daily carry. The textured handle ensures a no-slip grip, giving users total control during detailed or high-pressure cuts. The flipper action is smooth and intuitive, while the button lock adds both safety and speed — no awkward two-hand closing required.
Whether you’re cutting rope at a job site, breaking down boxes, shaving kindling for a campfire, or responding to tactical demands, the F3 Charlie is built to perform. The reinforced pivot design ensures consistent deployment, while the slim profile and pocket clip make it easy to conceal and carry.
