Customizing your daily pocket setup is one of the most practical aspects of modern EDC culture. The Bestech DUCI micro-flipper excels in versatility, offering an innovative modular design that adjusts to fit different carry styles. Manufactured by Bestech in collaboration with celebrated Polish knife designer Ostap Hel, this sub-two-inch folder features a unique quick-release tail ring. Based on the mechanical steps demonstrated in the popular Bestech DUCI ring removal video tutorials, this step-by-step guide walks you through safely detaching, reconfiguring, and maintaining your knife setup.
The Engineering Behind the Quick-Release Ring System
Before performing the removal process, understanding the underlying mechanics ensures smooth operation without damaging your hardware.
Ostap Hel engineered the tail ring to bridge the gap between sub-compact carry and full-hand ergonomics. Rather than using permanent screws or Torx hardware, the ring attaches via an internal spring-loaded detent interface.
Key mechanical components include:
-
Recessed Spring-Loaded Push Button: Sits flush along the spine of the tail ring to prevent accidental disengagement inside your pocket.
-
Internal Locking Pin: Secures the ring tightly against the rear backspacer of the titanium handle scales.
-
Precision Alignment Channels: CNC-milled grooves ensure zero side-to-side wobble or rattling when the ring is engaged.
Step-by-Step Guide to Removing the Tail Ring
Follow these straightforward steps as shown in the demonstration video to remove the tail ring in seconds without needing any tools.
Step 1: Ensure Safe Blade Position
Verify that the blade is fully folded into the handle housing. Never attempt to manipulate the tail ring or handle hardware while the blade is open.
Step 2: Locate and Depress the Push Button
Hold the titanium handle firmly in your non-dominant hand. Use your thumb or index finger to press firmly down on the recessed push button located near the base of the tail ring.
Step 3: Disengage and Slide
While keeping constant pressure on the push button, gently slide the ring assembly away from the handle body. The internal locking pin will release from the backspacer notch, allowing the ring to slip off cleanly.
Step 4: Safely Store the Ring Hardware
Place the removed ring in a dedicated organizer pouch, gear tray, or storage box so it remains clean and accessible for future configurations.
Tailoring Your Carry Mode to Your Daily Environment
Removing or installing the tail ring transforms how the knife handles, carries, and feels in hand.
Extended Grip Configuration (Ring Installed)
With the tail ring attached, the knife offers a full four-finger grip. This configuration excels when:
-
You need maximum leverage for heavy cardboard breakdown or cutting industrial zip ties.
-
You carry the knife inside deep pocket slots or pouch webbing and want a quick finger-pull tab.
-
You have larger hands and prefer a more substantial handle purchase.
Ultra-Compact Configuration (Ring Detached)
Detaching the ring reduces the overall length, leaving an ultra-compact handle. This setup is ideal when:
-
Carrying in the fifth pocket (coin pocket) of standard denim jeans.
-
Wearing lightweight summer shorts, formal dress slacks, or suit trousers without pocket sagging.
-
Keeping your pocket profile as discreet and minimalist as possible during daily urban commutes.
Uncompromised Performance with CPM-20CV Steel
Regardless of whether you carry the DUCI with or without its tail ring, the cutting core remains built for heavy-duty tasks.
The knife features a 1.97-inch (50 mm) modified drop-point blade crafted from American-made CPM-20CV powder metallurgy super steel. Featuring a stout 0.13-inch (3.2 mm) stock thickness and a high flat grind, it easily slices through thick packaging, ropes, and plastic strapping without dulling or chipping.
Maintenance Tips for the Quick-Release Mechanism
To ensure the push-button mechanism operates smoothly across months of daily use, keep these simple maintenance habits in mind:
Clear Pocket Lint: Use a can of compressed air or a soft brush to blow out pocket dust from the backspacer cavity whenever the ring is removed.
Apply Minimal Lubrication: Place a single drop of high-grade pivot oil onto the spring pin assembly periodically to maintain a smooth button press.
Check Lockbar Engagement: Regularly inspect the titanium Frame Lock and its stainless steel lockbar insert to keep the ceramic bearing action snapping open cleanly.
Final Thoughts: Modular Adaptability Made Simple
Following this step-by-step guide based on the Bestech DUCI ring removal video demonstrates how easy it is to customize your knife setup. By pairing a legal-friendly sub-2-inch CPM-20CV blade, a rigid TC4 titanium Frame Lock, and a tool-free quick-release system, Bestech and Ostap Hel have created a micro folder that easily transforms to match any everyday carry need.
