The Microtech Combat Troodon OTF 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 one of the largest OTF production knives available with an overall length of 9.5 inches. The Microtech Combat Troodon features a 3.8" stainless steel blade. The 5.75" handle is orange anodized aluminum and features black tactical 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. The aluminum handle features a double action thumb slide that allows for super fast blade deployment and retraction with the push of your thumb.
