When evaluating a compact cutting tool for daily carry, understanding exact physical dimensions and build materials is essential for gear enthusiasts. The Bestech DUCI is a micro flipper engineered by Bestech in collaboration with celebrated custom designer Ostap Hel. Designed specifically to maximize cutting utility while remaining legal in regions with strict blade limits, this sub-2-inch folder offers a compelling package for modern EDC setups. In this comprehensive specifications breakdown and measurement guide, we analyze the dimensions, steel composition, weight distribution, and hardware mechanics that define this premium pocket knife.

Blade Geometry and Dimension Analysis
The blade profile of the Bestech DUCI is intentionally engineered to deliver high cutting efficiency despite its compact footprint.
1. The 1.97-Inch Blade Length Advantage
Measuring exactly 1.97 inches (50 mm) from tip to ricasso, the blade easily satisfies municipal regulations that prohibit blades measuring 2.0 inches or longer. This sub-2-inch profile makes it an ideal urban utility blade.
2. Blade Thickness vs. Slicing Performance
At 0.13 inches (3.2 mm) thick, the blade stock is noticeably stouter than standard micro pocket knives. This added thickness ensures lateral strength when piercing tough materials, while the high flat grind provides a thin edge behind the bevel for effortless slicing.
3. CPM-20CV Steel Characteristics
The selection of CPM-20CV powder metallurgy steel delivers exceptional performance metrics:
-
High Wear Resistance: Vanadium carbide content protects the edge against abrasive wear.
-
Corrosion Immunity: High chromium content prevents pitting and rust from sweat or moisture.
-
Edge Retention: Holds a working edge up to four times longer than standard stainless steels.
Handle Architecture and Ring Measurements
Ergonomics on micro-knives often suffer due to limited hand surface area. Ostap Hel solves this through precise handle geometry and modular attachment features.
1. Overall Length Options
With the tail ring installed, the Bestech DUCI measures 6.38 inches (162 mm) overall. This extended tail allows for a full four-finger grip via the finger ring. When the quick-release ring is detached, the total length drops significantly, transforming it into a ultra-compact coin-pocket folder.
2. Modular Quick-Release Ring Mechanics
The tail ring is secured by an internal spring-loaded locking pin. Pressing the recessed push button disengages the pin instantly, permitting effortless ring removal without requiring Torx keys or specialized tools.
Lockup, Pivot, and Action Mechanics
A secure lockup mechanism is essential when working with a thick 3.2 mm blade stock.
Frame Lock Lockup & Safety: The primary locking mechanism relies on an integral TC4 titanium Frame Lock. To eliminate lock-stick and long-term titanium wear, Bestech integrates a hardened stainless steel lockbar insert.
Ball Bearing Pivot System
The pivot features caged ceramic ball bearings riding on hardened steel washers. Combined with a tuned detent ball, light index finger pressure on the flipper tab deploys the blade quickly with a crisp tactile click.
Material Configurations (Model BT2605 Variants)
Bestech produces the DUCI in multiple aesthetic configurations to suit individual collector preferences:
-
BT2605A / B / C / E / F: Feature raw stonewashed, satin, or anodized TC4 titanium handles, with select models incorporating carbon fiber inlays.
-
BT2605D: Features a custom flamed titanium handle with vibrant, rainbow-like anodization patterns across the titanium surface.
Summary Measurement Checklist
Whether you are looking for an urban-legal folder or a precise utility slicer, the Bestech DUCI combines high-end materials (CPM-20CV steel and TC4 titanium) with accurate manufacturing tolerances. Its sub-2-inch blade, 3.2 mm thickness, and 6.38-inch modular length make it one of the most versatile compact flippers in its class.
