TacKnives MD3DE OTF is a MEDIUM fully automatic double action OTF (Out The Front) knife that comes standard with CNC aviation Zinc Alloy handles. The 100% CNC Construction of the handle makes for a precise fit of the handle and the blade. The 100% CNC Construction is not only for the exterior, it is also the interior and the operating components as well. The CNC aviation Zinc Alloy is extremely strong, lightweight and durable.

All TacKnives knives are designed with EDC (Everyday Carry) in mind. Therefore, ergonomics are everything. The MD3DE handle shape is well balanced and feels natural in the hand of the operator. The handle is coated with Anti-Slip industrial silicon for the ultimate grip to keep the knife firmly in the hand of the operator during any operations. Additionally, both sides of the handle is CNC machined hollowed out and replaced with carbon fiber to reduce the weight of the knife.

The blade of the MS3DE is a straight double edge style blade. The double edge style is an ultra classic style of blade that has been around for a long long time.

Inside the MD3DE OTF knife, you will find our new dual spring technology where it gives the MD3DE its consistent firing and super rapid deployment. The trigger is designed to be on the main face of the knife where your thumb naturally rest for quick deployment. The trigger action is both crisp and smooth.

Since every TacKnives knives are designed with EDC in mind, you will find almost all TacKnives knives are equipped with a ballistic glass breaker and a stainless steel pocket clip. Both features are extremely essential in an EDC knife. In the case of an emergency, an operator has quick access to his or her knife through accessing it from his or her pocket and rapid deployment of the blade. The glass breaker can easily break a common window.

All TacKnives OTF knives are extremely safe to operate and use. TacKnives OTF knives come with a built-in safety that will not allow the blade to fully deploy if anything is obstructing its path. Once in “safety mode” the blade will need to be reset by pulling the blade all the way into its locking position making it fully functional again.
