The Microtech Ultratech Gen IV 11224-1NC is an OTF Double Action automatic knife featuring a double-edged blade made of Böhler M390MK steel, a black finish, and a 6061-T6 aluminum handle in the Natural Clear finish. The model utilizes the Dual-Fuel Drive Train™ system and a classic Slide Lock, combining the Ultratech’s slim profile with modern automatic mechanics.
The symmetrical D/E blade gives the design its distinctive look and ensures a centrally located tip, while the light-colored Natural Clear handle creates a strong contrast with the black blade. The push/pull thumb slider automatically extends and retracts the blade, and the reversible titanium tip-down clip allows you to adjust the carry style for right- or left-handed use.
Böhler M390MK – High-Wear-Resistant Steel
The blade is made of Böhler M390MK steel, valued for its high corrosion resistance, excellent edge retention, and wear resistance. In an OTF automatic knife, these properties are well-suited for regular use and help maintain an effective cutting edge for a long time. The flat grind ensures smooth glide of the blade through the material.
Double Edge – symmetrical geometry and a central cutting point
The Double Edge profile features a symmetrical geometry with a centrally located tip and double-sided sharpening. This design provides the distinctive silhouette characteristic of classic OTFs and excellent control over the blade tip. The flat grind preserves functional cutting properties while maintaining a slender blade profile.
Black blade finish
The black blade finish emphasizes the symmetrical line of the blade and gives the design a more technical character. Paired with the light-colored Natural Clear handle, it creates a striking contrast that strongly accentuates the Double Edge geometry.
Natural Clear 6061-T6 Aluminum
The handle is made of 6061-T6 aluminum with a Natural Clear finish. The material provides adequate rigidity while remaining relatively lightweight, and the slim profile makes it easy to carry around daily. The light, metallic finish complements the minimalist design of the Ultratech Gen IV.
Dual-Fuel Drive Train™ and Automatic OTF Mechanism
Dual-Fuel Drive Train™ powers the OTF Double Action mechanism. Pushing or pulling the thumb slider extends the blade to the open position, while moving it in the opposite direction automatically retracts it into the Handle. The entire cycle can be operated with one hand.
Slide Lock and Titanium Clip
Slide Lock works in conjunction with the automatic mechanism, ensuring proper operation of the blade during opening and closing. The titanium clip can be mounted on the right or left side in a tip-down configuration, allowing you to customize how you carry the knife to suit your individual preferences.
Why Choose the Microtech Ultratech Gen IV 11224-1NC?
This is the perfect choice for users looking for a distinctive OTF knife with a symmetrical Double Edge blade and bold, high-contrast styling.
