The Microtech Ultratech Gen IV 11234-10RD is an OTF automatic knife featuring a Tanto blade made of Böhler M390MK steel with a stonewashed finish and a red 6061-T6 aluminum handle. The model features the Dual-Fuel Drive Train™ system, Slide Lock, and a Double Action mechanism, allowing the blade to be automatically extended and retracted with one hand.
The Red variant stands out with its vibrant handle color paired with a bright, functional blade finish. The Ultratech’s distinctive proportions offer a good balance between blade length and the slimness of the overall design, while the reversible titanium clip makes it easy to customize the carrying style to suit the user.
Böhler M390MK – Edge Durability and Corrosion Resistance
The blade is made of Böhler M390MK steel, valued for its high corrosion resistance and excellent edge retention. The material is well-suited to the nature of an EDC knife, which is designed to maintain high cutting performance with regular use. The flat grind facilitates effective blade guidance through the material.
Tanto – Distinctive Functional Geometry
The Tanto profile features a sharply defined tip and a two-segment cutting edge. The front section works well for making precise initial cuts, while the longer main section remains effective for cutting cardboard, tape, and other everyday materials.
Stonewashed – a practical blade surface
The blade features a stonewashed finish, which creates a matte and slightly irregular surface. This texture effectively masks minor signs of everyday use and gives the knife a more rugged character, while contrasting with the vivid red handle.
Red 6061-T6 Aluminum
The handle is made of 6061-T6 aluminum in Red. The material provides adequate rigidity with moderate weight, and the slim profile makes it easy to carry comfortably. The red color scheme gives the model a more distinctive look and allows you to quickly distinguish it from the more subdued Ultratech variants.
Dual-Fuel Drive Train™ and Slide Lock
The Dual-Fuel Drive Train™ controls the automatic movement of the blade in the OTF Double Action mechanism. Sliding the slider extends the blade, while sliding it back retracts the blade into the handle. Slide Lock works in conjunction with the entire system, ensuring its proper operation in working positions.
Titanium Right/Left Clip
The knife is equipped with a titanium clip that can be mounted on the right or left side in a tip-down configuration. This feature allows you to adjust how you carry the knife to match your dominant hand and enhances its functionality in everyday use.
Why Choose the Microtech Ultratech Gen IV 11234-10RD?
This model is designed for users who want to combine the distinctive Ultratech design with a more striking color scheme and a practical stonewashed finish. M390MK, Tanto, Dual-Fuel Drive Train™, and full Double Action automation come together to create a modern EDC setup.
