The Microtech Combat Troodon OTF automatic knife is named after the Troodon dinosaur and is the larger version of the Troodon OTF knife which debuted in 2006. The Combat Troodon is the largest OTF production knife available with an overall length of 9.5 inches. The Microtech Combat Troodon features a 3.8" stainless steel double edge dagger style blade. The 5.75" handle is Red anodized aluminum and features a bead blast finish hardware, glass breaker and pocket clip. Yes this is a larger OTF knife but it feels great in the hand thanks to the jimping in the handle.
