The Microtech Combat Troodon (say it TROH-o-don) is the duty knife of the OTF world. It was built for law enforcement, military, and first responders who needed a substantial blade that deploys with one hand under stress, and the Gen III spec sheet reads accordingly: 9.5 inches overall, a 4-inch blade, and about 5 ounces of anodized 6061-T6 aluminum with an integrated glass breaker at the base.
The double-action thumb slide fires and retracts that big blade with real authority, and the grooved chassis keeps it locked in a gloved or wet hand. Machined in the USA, it is the flagship hard-use knife in the Microtech lineup, and the biggest OTF most people will actually carry every day.
Gen III is the deepest overhaul the platform has seen. The new drivetrain gives it what Microtech calls the smoothest deployment it has ever produced, and the firing switch now rides on a milled platform that breaks up pocket lint and debris before they add friction, stretching the intervals between cleanings. The chassis carries a reversible milled titanium pocket clip with a ceramic ball, and Torx hardware throughout means you can disassemble it for maintenance without a fight. Gen III also stretched the standard blade to 4 inches, up from the 3.8 inches of earlier generations. It is a duty knife that got easier to live with.
Current blades run Bohler M390MK, a version of M390 that Bohler tuned exclusively for Microtech, and you can see how it stacks up in our comparison of every major knife steel. The standard configurations cover single edge, double-edge dagger, and tanto, but this platform is where Microtech's signature grinds really stretch out: the Hellhound and Warhound, the Interceptor, a proper Bowie, and the HS Rescue, with limited runs reaching into Baker Forge Damascus territory. Between those grinds and the Signature Series handle treatments, no two collections end up looking alike.
The names confuse people, so here is the short version: the Combat Troodon is the full-size duty knife, and the standard Troodon carries the same silhouette and mechanism at roughly 75 percent scale for everyday pockets, with the Mini Troodon shrinking it further still. If you want maximum blade, presence, and grip real estate, the Combat is the answer; if you want a slimmer full-size OTF, the Ultratech is the move. Among tactical knives, few tools earn their keep on a belt or in a cruiser like this one.
