Description
The Microtech Ultratech is the benchmark of OTF automatic knives — a double-action out-the-front mechanism that fires and retracts the blade with equal authority via a sliding thumb switch.
The Bohler Elmax blade delivers a rare combination of edge retention, toughness, and corrosion resistance, while carbon fiber inlays over the aluminum chassis add tactile sophistication.
A best OTF automatic knife for discerning collectors who demand the gold standard in out-the-front deployment, premium steel, and American craftsmanship.

**Out the Front, Into the Future**
Slide the switch forward and feel the blade launch from the handle with electromagnetic certainty — then retract it with a reverse pull, the mechanism so smooth it feels frictionless.
The carbon fiber inlay catches light as you rotate the knife, revealing the weave pattern beneath a glossy clear coat — a visual reminder that this is no ordinary tool.

**Forged in the Blue Ridge Mountains**
Microtech manufactures every Ultratech in their Bradford, Pennsylvania facility, where CNC lathes carve each aluminum chassis from solid billet and skilled technicians hand-assemble the intricate OTF mechanism.
Bohler Elmax steel — a third-generation powder metallurgy alloy from Austria — is selected for its extraordinary balance of hardness, toughness, and stain resistance, then ground to a mirror-polished or stonewashed finish.

Knife Care & Maintenance
Keep your blade performing at its best. Rinse and dry after each use to prevent corrosion. Apply a thin coat of mineral oil to the blade periodically. Sharpen with a whetstone or honing rod at a consistent angle. Store in a sheath, knife roll, or magnetic strip — never loose in a drawer. For carbon and Damascus steel, wipe after contact with acidic foods. For folding knives, clean the pivot area and apply a drop of lubricant to ensure smooth deployment.
