Product Description
The Microtech Ultratech has been the company's flagship knife since 1999, and the Gen III Signature Series is its latest evolution: a double-action OTF with a 3.55" M390MK blade, a 6061-T6 aluminum handle, and an upgraded glass breaker.
M390MK is Microtech's designation for its M390 powder-metallurgy stainless steel, known for strong edge retention and good corrosion resistance. In practice, that means a blade that stays sharp through long stretches of everyday cutting and resists rust with basic care. The stonewash finish helps hide scratches from daily use. Microtech builds the Gen III with its Crud Kutter and Dual-Fuel Drive Train features, Torx screws throughout, and a machined 6061-T6 aluminum handle.
- Blade: 3.55" M390MK, stonewash finish, plain edge. 8.54" overall.
- Handle: Machined 6061-T6 aluminum secured with Torx screws, with an upgraded glass breaker.
- Deployment + Lock: Double-action out-the-front (OTF) automatic. The thumb slide both deploys and retracts the blade.
- Carry: Pocket carry. Knife only; no sheath included.
Ideal for: OTF collectors who want Microtech's flagship model; experienced automatic-knife owners looking for a full-size double-action OTF; and Microtech fans adding a Signature Series piece.
Glass breaker: Laws on knives with glass breakers and similar tools vary. Check your local laws and use this tool lawfully.

Microtech Ultratech Gen III: Frequently Asked Questions
Answers to the most common questions about the Microtech Ultratech Gen III Signature Series (1117EX-10S).
Is it legal to own or carry an OTF automatic knife like the Ultratech where I live?＋
Automatic knife laws, including those covering OTF knives, vary by federal, state, and local jurisdiction, and they change. Before ordering, check the laws where you live and carry. The American Knife and Tool Institute keeps state-by-state summaries at akti.org. Knifeworks does not provide legal advice.
How does a double-action OTF knife work?＋
On a double-action out-the-front (OTF) knife, the blade slides straight out of the front of the handle. The Ultratech's thumb slide both deploys the blade and retracts it, so you can open and close it with one hand. Keep your fingers clear of the front of the handle when deploying.
What is new in the Ultratech Gen III?＋
Microtech describes the Gen III as the latest version of the Ultratech, which it has updated many times since 1999. This generation adds Microtech's Crud Kutter and Dual-Fuel Drive Train features, Torx screws, and an upgraded glass breaker on a 6061-T6 aluminum handle.
What is included with the Ultratech Gen III?＋
This is a knife-only listing, so no sheath is included. Packaging and contents are subject to change by the manufacturer.
How do I care for the Ultratech?＋
The M390MK blade is stainless, but keep it clean and dry after use. Keep pocket lint and debris out of the blade channel, and follow Microtech's guidance before using any lubricant in the mechanism.
