Microtech Ultratech Gen IV D/E Double Edge Half Tri-Grip Purple Abrasion Aluminum M390MK OTF Automatic Knife (3.55" Blade) 11224HT-1 PUAA

The Microtech Ultratech Gen IV fires crisp and hard as a flagship OTF automatic, and this Double Edge build wears a Purple Abrasion finish that reads subtle in the pocket and unmistakable in the hand.

• M390MK Purple Abrasion Double Edge Dagger Blade - Bohler M390MK is a premium powder stainless prized for long edge retention and strong corrosion resistance, though it fights back on the stones. The symmetrical dagger grind splits piercing reach against everyday cutting.
• Gen IV OTF Automatic Deployment - Thumb the slide and the blade fires crisp and hard, then retracts on the smoothest drive system Microtech has built. The switch rides a milled platform that sheds pocket lint and grit, so the throw stays firm and positive.
• Half Tri-Grip Aluminum Chassis - The contoured aluminum body trims weight and sits lighter in hand than earlier Ultratechs. Half Tri-Grip texturing runs across the back half for a grippy tactile accent, though set that far back it does more for character than for grip.
• Titanium Pocket Clip - The milled titanium clip carries tip-down and reverses for left or right, riding a ceramic ball detent that lets it glide on and off a pocket seam without clawing at fabric. Sturdy build and a firm bite keep the knife planted on a belt or strap.

The Microtech Ultratech

The Microtech Ultratech has anchored the Microtech OTF lineup for years as the flagship out-the-front automatic. The Gen IV update reworks the internal drive for smoother, more reliable deployment and easier maintenance, with a stainless glass breaker set into the pommel for hard-use moments. Every example runs a double-action mechanism that fires and closes from the same thumb slide, which is why the platform earns its name for one-handed speed when a second hand is busy. Microtech machines each one in the USA to exact tolerances.
